[Maria-discuss] New Question: Problem with multi master replication and a trigger with mariadb 10.0.10.
by AskMonty KB 10 Apr '14

10 Apr '14

Hello, A new question has been asked in "Triggers" by wschwauer: -------------------------------- I have a problem with multi master replication and a trigger with mariadb 10.0.10. First. I have installed master db with name DB1 on a Windows system 1 master1 with a table m1, m2, m3, mg Second, I have install “slave” db with name DB1 on a Windows system 2 slave1 with a table s1, s2 Now I setup a row based replication with the table m1 from master1 to slave1. Next I setup a row based replication with the table s1 from slave1 to master1. Now I have a master with table m1, m2, m3, mg and s1 and a slave with table s1, s2 and m1. All replications work well. Ad next I create a trigger on master to manipulate and copy the data from table s1 to mg, but it do not work. I found this information (https://mariadb.atlassian.net/browse/MDEV-5095) but I have not the variable slave_run_triggers_for_rbr or slave_run_triggers. When I create the same trigger on master with table m1 and mg, it still works. But it not work with the replication table s1. I think it is a problem with the replication table s1. Can anyone help me? -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/problem-with-multi-master-replication-and-a-trigge…

[Maria-discuss] Trouble getting MariaDB to start up
by Jonathan Gazeley 07 Apr '14

Hi folks, I'm reasonably experienced with MySQL and MMM for cluster management but now I am working on a project to replace this with a MariaDB Galera cluster. Basic system info: [jg4461@db3 ~]$ uname -a Linux db3.resnet.bris.ac.uk 2.6.32-431.11.2.el6.x86_64 #1 SMP Tue Mar 25 19:59:55 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux [jg4461@db3 ~]$ cat /etc/redhat-release CentOS release 6.5 (Final) [jg4461@db3 ~]$ mysql -V mysql Ver 15.1 Distrib 5.5.36-MariaDB, for Linux (x86_64) using readline 5.1 I've set up a Galera prototype with two nodes and I got the clustering working. Then I decided to add a load of config options from my old MySQL install to the MariaDB install, and now it fails to start up, but doesn't give an obvious error message. The options were mostly to do with InnoDB buffers etc. This is the output in the log file /var/lib/mysql/db3.resnet.bris.ac.uk.err, the init script hangs for ages after this without giving any further output. 140331 15:07:49 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 140331 15:07:49 mysqld_safe WSREP: Running position recovery with --log_error='/var/lib/mysql/wsrep_recovery.mlbT89' --pid-file='/var/lib/mysql/db3.resnet.bris.ac.uk-recover.pid' 140331 15:07:51 mysqld_safe WSREP: Failed to recover position: '140331 15:07:49 InnoDB: The InnoDB memory heap is disabled 140331 15:07:49 InnoDB: Mutexes and rw_locks use GCC atomic builtins 140331 15:07:49 InnoDB: Compressed tables use zlib 1.2.3 140331 15:07:49 InnoDB: Using Linux native AIO 140331 15:07:49 InnoDB: Initializing buffer pool, size = 1.5G 140331 15:07:49 InnoDB: Completed initialization of buffer pool 140331 15:07:49 InnoDB: highest supported file format is Barracuda.

[Maria-discuss] New Question: crash recovery
by AskMonty KB 01 Apr '14

01 Apr '14

Hello, A new question has been asked in "Backing Up and Restoring" by joemurray: -------------------------------- An XtraDB database running in MariaDB - no cluster, no replication - has been crashing about 15 x per day for 3 days and we suspect it may be corrupt. We don't see any reason in the log files for the crashes. We have taken a mysqldump and restored into a new db and run mysqlcheck on the new db and not fond any errors, but I suspect that the dumping and restoring has hidden them. After testing a staging site with this new database we are planning to repeat the process of dumping and restoring into a new db and then making it live. I intend to run mysqlcheck on the production database once it is no longer in production. Any other suggestions from DBAs to this developer? -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/crash-recovery/

[Maria-discuss] New Question: Multi Master Replication

Hello, A new question has been asked in "MariaDB Documentation" by eddow: -------------------------------- Greetings, I am attempting to set up Multi Master Replication. So far, I have been able to set up multiple masters and data is replicated to one slave. This works great. What I am having a problem with is if I add a new master. When I add the master the data in the slave table is truncated and only the data from the new master is replicated. I loose all my old data in the slave. Example: Master 1300: +----------------+ | name | +----------------+ t1300 Master 13: +----------------+ | name | +----------------+ t13 +----------------+ Slave: +----------------+ | name | +----------------+ t1300 t13 +----------------+ On the slave I do this: change master 't68' to master_host='10.79.84.149', master_user='replication_user', master_port=3306; start slave t1300; select * from name; Slave: +----------------+ | name | +----------------+ t68 +----------------+ -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/multi-master-replication/

[Maria-discuss] Does ADD/DROP INDEX update the InnoDB buffer pool?
by Markus "Shorty" Uckelmann 25 Mar '14

25 Mar '14

Hi all, When adding or dropping a primary and/or secondary index is the InnoDB buffer pool updated too? Is the pool changed in place or will the LRU algo just evict to make room? In the second case buffers of other tables on the server might be affected too and the server would run with a more or less cold buffer pool. We have to fiddle with indices on production servers, which by itself is a precarious matter. So I tried to find out how ADD/DROP INDEX operations affect the memory/buffer pool of our servers. Since I wasn't able (or too stupid) to find something about this topic it would be great if someone could help me out and point me in the right direction. BTW: Version is MariaDB 5.5 Cheers, Shorty

[Maria-discuss] Mariadb Java Driver useOldAliasMetadataBehavior and useColumnNamesInFindColumn
by Peter Mclarty 18 Mar '14

18 Mar '14

Hi Our context file presently has the useOldAliasMetadataBehavior=true in it to handle select count(*) as Bignumber type scenarios.( select as as b from table ) We tried using the mariadb driver as we have started the journey to using mariadb.5.5 and had a meltdown in our app (dev only thanks). I have done some research and it as i read it the mariadb code doesn't honour that parameter. I have done some research and one article stated With JDBC drivers version 4.0 and later you will eventually not get the aliasName As i haven't fully digested the JDBC 4.0 spec, barely scratched the surface am I right to conclude Maria and MySQL drivers will not eventually support this behavior and what is the approach to this using aliases or the selact a as b type scenario. Just point me to the pages is fine Any assistance appreciated Cheers -- *Peter McLarty* *Data Analyst DBA* Compare The Market -- Compare The Market is a brand and trading name of Compare The Market (Pty) Ltd (CTM).

[Maria-discuss] New Question: pre-seeding databases from remote servers for multi-source replication
by AskMonty KB 17 Mar '14

17 Mar '14

Hello, A new question has been asked in "Backup, Restore and Import" by ivesstoddard: -------------------------------- I'm in the process of pre-seeding a mariadb 10.0.9 multi-source replica server with databases from remote 5.5 servers. I'm looking for the fastest and most stable way of doing this (preferably without using mysqldump). I'm curious if there is a way to import entire databases directly from block-level snapshots, similar to the transportable tablespaces (only on a database level instead of a table level, by copying .idb/.frm/etc. files directly to the target server). NOTE: Transportable tablespaces aren't yet available in 5.5 and also have to be done on a table-by-table basis. Some of the databases are large enough that running mysqldump & import will are impractical. Not only will this process take a considerable amount of time, but to do this in a way that is closest to a snapshot will require a separate server instance to ensure all transactions have been committed to the tablespaces. Is there anyone out there looking at multi-source replication who has a simple solution to this that i might be overlooking? Thank you. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/pre-seeding-databases-from-remote-servers-for-mult…

[Maria-discuss] MariaDB vs. MySQL error codes (1900+)
by Felipe Gasper 17 Mar '14

17 Mar '14

Hi everyone, I notice that MariaDB is using the 1900+ range for its own error codes; however, MySQL 5.7, at least, has a few errors in that range as well. Are error codes just going to be an area of increasing conflict between the two, or is there a plan to migrate MariaDB codes to a different numbering scheme? -Felipe Gasper Houston, TX

Hi, My name is Ngong Ivoline.I am a second year student reading Computer Engineering in the University of Buea (Cameroon in West Africa). I am very excited working with an open source organization as i will finally have the chance to share my ideas as well as learn from others. I love coding and i am proficient in Java ,C and mysql.I will like to not only test but improve my skills by taking part in a google summer of code 2014. One of my goals as an African woman is to encourage the growth of programming in my community, country and continent as a whole. I am interested in the project to statistically optimize mysql-test runs by running less tests. It will be great if i get some guidance on how to continue from here.Look forward to participating in this group. Cheers!! Ivoline.

[Maria-discuss] postfixadmin and mariadb, want to add support for user 'groups'
by Tanstaafl 12 Mar '14

12 Mar '14

Hello all, We have a postfixadmin+mariadb sql database we have been using for many, many years (well, only recently migrated from mysql to mariadb, and it was totally transparent, so thanks for that!). This system is rock solid, and we have no desire to change it. We are in the process of setting up SOGo groupware, amd have run into a stumbling block. Not a show stopper, but it definitely put a heavy burden on me, as the SysAdmin. SOGo can Active Directory just fine for testing Group Memberships for purposes of applying ACLs (for shared calendars, contacts, etc)... We intentionally do not use SSO - we enforce very strong email passwords, but allow much weaker AD computer passwords - so email AUTH happens with our SQL DB. The problem is, SOGo does not have support for using 'Groups' for ACLs when using SQL for the AUTH backend. It also does not (yet) have support for different AUTH and USER DB backends. So, as things stand now, I'm going to have to manually add every single individual userid to every single resource they will need to have access too, rather than just doing this with groups. So, my first questions is, has anyone every come up with a decent schema that provides for managing user groups in the same way as AD groups that scales reasonably well? I'm very dangerous when it comes to this stuff, so can't even attempt this myself, but I have some options available to help get this done, especially if I can get some help/advice with getting started. One thing I do know is the SOGo guy had to create a 'View' to use, so whatever we end up using will have to work inside a View (probably displaying my ignorance to the world with that comment - is pretty much everything in an SQL DB compatible with 'Views'?)... I'd dearly appreciate any help anyone is willing to give... Thanks, Charles

[Maria-discuss] InnoDB selected projects (corrected links)
by Jan Lindström 12 Mar '14

12 Mar '14

Hi all, After careful weighting and selection process, I have selected following two projects as a starting point to improve InnoDB (1) InnoDB file space defragmentation Description: External tool to physically delete delete marked rows from InnoDB file space and freeing unused file space. https://mariadb.atlassian.net/browse/MDEV-5834 (2) InnoDB fast bulk load Description: External tool to load CVS file directly to InnoDB file space (innodb_file_per_table = 1). https://mariadb.atlassian.net/browse/MDEV-5835 Now, I hope these projects mostly represent the most frequently requested features and are most usable to current customers and/or potential new customers. Next, I would hope some indication which one of the selected project you would like to see first. Votes can be added above links.

Hello, A new question has been asked in "MariaDB community" by mdavies5: -------------------------------- I installed v5.5.36 on a new Mint16 installation and it started ok. I then modified my.cnf to point to an existing data directory. I made sure that all folders and files were owned by mysql user and the mysql group had permissions to read/write. I also deleted existing files ib_logfile0/1, ibdata1 and aria_log_control as I know these must be recreated. When restarting MariaDb I get: Can't create/write to file '/home/michael/mysql/aria_log_control' (Errcode: 13). Files ib_logfile0 & 1 and ibdata1 were created ok so it is not a permissions problems. Why does only aria_log_control fail to create. If I copy all this data to default /var/lib/mysql and reset my.cnf then they work fine -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/v5536-will-only-use-default-data-directory/

Ok i wasn't able to reproduce the issue fully, now data is different ... but again, "skipped rows" number changes, and index sizes differ a lot: Uniq index: http://screencast.com/t/SrBS1L5xeB8 http://screencast.com/t/3dVMU7b69AH2 Normal index: http://screencast.com/t/Zl5Jm2OZ http://screencast.com/t/P3SA8U6duly But again, unique index is working much worse than not unique... while it's bigger http://screencast.com/t/rjexoWKwFF http://screencast.com/t/qYdsmRbRbmG7 I'll quickly explain how tables were created... i first took part of the data with unique index, and made smaller copy, thats table 1 Then i just copied the table changed the index to non-unique. After this i copied the tables once again to be sure files are not fragmented, etc. SHOW WARNINGS returns nothing in both cases. It seems that the additional knowledge (only single row with same data) should make the optimizer and query behave better but it's actually behaving much worse... -- Query for reference: EXPLAIN extended SELECT attrib_id, raw_stats_value_id, sum(impressions)FROM raw_stats_other_copyi1_copy INNER JOIN raw_stats_lookupON raw_stats_lookup_id = raw_stats_lookup.idWHERE domain = 'mydomain.com'AND date = '2014-02-10'GROUP BY attrib_id, raw_stats_value_id; -- Thanks, Slawomir.

[Maria-discuss] MariaDB & MySQL community event 3rd of April 2014 in Santa Clara
by Michael Widenius 05 Mar '14

05 Mar '14

Hi! I am happy to announce that the MariaDB Foundation is organising a MariaDB & MySQL community event in Santa Clara on Thursday the 3rd of April. The venue is the Hilton Santa Clara hotel, a short walk from the Percona Live 2014 event. You can find more information on my blog at: http://monty-says.blogspot.fi/2014/03/mariadb-mysql-community-event-2014-in… We already got some very interesting talks and speakers, but I would like to see even more talk proposals. It's ok to propose a talk that it's also hold at Percona Live. As this event is free, I expect a totally different group of attendees, so that should be fine! When we have got a nice list of proposed talks, we will post them here so that everyone has a chance of commenting of which talks should be accepted. (Sorry, but this time we don't have time to create a proper selection committee so we have to do this a bit rough) Personally I will talk about MariaDB 10.0, which should be declared stable by then. Hope to see many MariaDB developers and users in Santa Clara! You can sign up for the event and/or dinner at: http://www.eventbrite.com/e/mariadb-mysql-community-event-2014-tickets-1080… Regards, Monty PS: Feel free to discuss the event on this email list! We want to have as many as possible participating in making this the best possible MariaDB and MySQL event.

Hello, A new question has been asked in "OQGRAPH" by prestonthayne: -------------------------------- So I added some rows to the data table before I created the graph table that then showed up just fine. I then added some more rows to the data table and did a select * on the graph table and the new rows weren't there. I did a shortest route query and they showed up. A subsequent select * query to the graph table and they were there. What triggered them to appear? I then added a few more and no matter what I do they won't show up. The last one that won't show up was a two way link ( insert into oq_backing (origid,destid) values (9,10),(10,9) ). That's not a problem is it? And lastly, is there any good documentation/literature around for how oqgraph works and how to use it?

[Maria-discuss] Codership's Galera patch part of standard MariaDB
by Honza Horak 20 Feb '14

20 Feb '14

Hi guys, my Google-foo is poor today and I can't find any discussion about "inclusion of Codership's Galera patch to standard code-source of MariaDB". I'd like to see that one could just use the wresp plugin and have a working Galera cluster (even if that would mean to introduce new engine) without having another instance of the package. Is that technically possible at all and if so, are there any thoughts like this? Thanks, Honza

[Maria-discuss] Implementing APPROXIMATE_COUNT(*)
by Tomek R 19 Feb '14

19 Feb '14

Hi, I have realised that whenever I am doing any query and want to count number of rows:SELECT COUNT(*) FROM atable WHERE <complicated condition>; On large tables (>10e6 rows), when the count is >100e3, it takes over a second... even when all the indexes are set up, etc... and with large counts, I have not been able to go below ~<1 s. So I would like to implement APPROXIMATE_COUNT(*) function, which checks, if, for example every 10th, 100th or 1000th row is present in my final output... and based on this statistics, return the approximate number of rows that given query produces. I am using MyISAM engine and would like to do the implementation on it, where the total number of rows is automatically stored. Obviously, it would be useful for anybody dealing with these huge aggregate websites, where users do not really need to know if their keyword search returned 1234567890 results or just 1.2e9 results... Please, can you advise me how to start this project? I.e. whether it's easy to do in SQL or whether I would have to start looking somewhere in the source code of MariaDB? I have plenty of time, programming/SQL experience, but no experience with maria/mysql source code. Tomek

[Maria-discuss] New Question: Data limit on joins with connect tables?
by AskMonty KB 18 Feb '14

18 Feb '14

Hello, A new question has been asked in "Connect" by benkendrick: -------------------------------- I am attempting run a query against two tables in a remote database with an inner join. These tables reside in a Progress Database. I have used the CONNECT engine via the ODBC connection that I have set up. The first query had 24 columns returned by the query, I got 930 rows as a result. If I reduce the number of columns that I select, the number of rows returned by the database goes up. Even with only two rows select, I only get about 12,000 rows. The total result should be 14,149 rows. I have used the same ODBC connection with LibreOffice Base and received the full number of rows. If I query each table individually, I get the full number of rows (The tables have a 1 to 1 relationship with the current data). I am using MariaDB 10.0.8 32-bit on Windows 7 querying a remote Progress Database. Is there some sort of data limit? I have noticed that the total number of data points (rows multiplied by columns) is between 20,000 and 24,000. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/data-limit-on-joins-with-connect-tables/

[Maria-discuss] Potential participation in Google Summer of Code 2014
by Colin Charles 15 Feb '14

15 Feb '14

Hi! We have applied to be part of the Google Summer of Code 2014 project, and hope to gain some new contributors. If you are on this list and think you can be a mentor for a project, please consider writing a note at: https://mariadb.com/kb/en/google-summer-of-code-2014/ I think the aim for the GSoC students code should be for 10.1 inclusion If you have any queries, don't hesitate to ask me about them, I'm happy to help. Typically mentors need about 4 hours or so per week to assist the student in seeing their project become a reality I encourage many to participate as its a rewarding experience. In 2013, we did participate, and got 3 features out of it: SQL ROLES, PCRE regular expressions, and a Kerberos authentication plugin Looking forward to seeing more happen in 2014! (here's hoping we get accepted into GSoC 2014 of course!) cheers, -colin -- Colin Charles, Chief Evangelist MariaDB | t: +6-012-204-3201 | Skype: colincharles

[Maria-discuss] Very slow insert with load data infile
by Pierre 12 Feb '14

12 Feb '14

Hello, Mariadb is getting slower and slower when I'm inserting a massive amout of data. I'm trying to insert 166 507 066 rows (12go) using load data infile '' into an empty table. I splitted my file in 13 parts of the same size because it was too long to insert in one shot. When I inserted more than 100M rows, it starts to be extremely slow. Here are the time for each load data infile : LOAD DATA INFILE '/tmp/hash/xaa' : 2min 49sec LOAD DATA INFILE '/tmp/hash/xab' : 2min 49sec LOAD DATA INFILE '/tmp/hash/xac' : 3min 48sec LOAD DATA INFILE '/tmp/hash/xad' : 3min 48sec LOAD DATA INFILE '/tmp/hash/xae' : 3min 49sec LOAD DATA INFILE '/tmp/hash/xaf' : 5min 59sec LOAD DATA INFILE '/tmp/hash/xag' : 10min 50sec LOAD DATA INFILE '/tmp/hash/xah' : 20min 7sec LOAD DATA INFILE '/tmp/hash/xai' : 47min 7sec LOAD DATA INFILE '/tmp/hash/xaj' : 4 hours 1 min 9.34 sec ( ouch !) LOAD DATA INFILE '/tmp/hash/xak' : still running... Now the task is running but mariadb is only using 2% cpu and read to the disk at 2500 Kb/sec (which is slow regarding the disk performance). There is a lot of disk space. If insertion speed continue to slow down at this rate, it will take weeks to insert the 3 remainings files ! It's only 166M rows so I think it's not normal. If I disable the "unique" constraint insertion speed is great but I need to be sure there is no duplicate and I also need an index. Can someone explain me what is happening internaly and why it is so slow ? Do you think if I just create an index (not a unique index) it will be faster ? The problem is I specially delegated this task of unique checking to mysql. If no solution, do you know a database or a key/value store with better for performance for this use case ? (create an index and remove duplicate ?) I can rearrange my table structure (at a cost of more disk space usage) to match a key/value structure. Here is my current table structure : CREATE TABLE `wallets` ( `p1` varbinary(20) DEFAULT NULL, `p2` varbinary(20) DEFAULT NULL, `data` varbinary(32) DEFAULT NULL, UNIQUE KEY `p1` (`p1`), UNIQUE KEY `p2` (`p2`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 ROW_FORMAT=FIXED; Computer specs: 16go RAM and 4x3.1 ghz, 2x1To (with 90% unused disk space) The configuration variables (I tweaked specially for this insertion job) : key_buffer_size = 6G # MyISAM: used with insert to an empty table bulk_insert_buffer_size = 6G # MyISAM/Aria: insert to a non empty table; default 8M myisam_sort_buffer_size = 6G # MyISAM: used for sort but only when : "CREATE INDEX", "ALTER TABLE" or "REPAIR TABLE" read_buffer_size = 6G # MyISAM/Aria/MERGE: allocated for each table scan, for order by, nested query caching, bulk insert into partitions sort_buffer_size = 4M # ALL: allocated each time a session need to do a sort myisam_max_sort_file_size = 128G # MyISAM: tmp file max size I'm using mariadb 5.5.31.

[Maria-discuss] Connect engine assistance needed with nested first node in XML

[Maria-discuss] New Question: Asynchronous Replication with Galera Cluster ?
by AskMonty KB 24 Jan '14

24 Jan '14

Hello, A new question has been asked in "Galera" by nicolasblanc: -------------------------------- My question is simple. Today i have a Galera Cluster with 3 nodes to write/read. And i want to put one(more to come) slave (asynchronous replication) to the cluster. As all my writes are located on 1 node, it's ok. But if i change the node on which the writes come... My slave is not synchronized anymore. I had to change the master of the slave to have the new written node as master. It seems that each galera node write only transactions from "real client" to replication binary log, not the ones from wsrep. Is there a way that i can ask to a Galera cluster node to always write commited transaction on the replication binary log ? Even if the transaction come from wsrep and not "real client" ? Thx in advance, -- Nicolas Blanc. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/asynchronous-replication-with-galera-cluster/

[Maria-discuss] Statistics/Counters for number SHOW INDEX FROM queries

22 Jan '14

Hi all, We have a lot of SHOW INDEX FROM queries coming from our ORM layer. Usually there is a mechanism to prevent this but it doesn't seem to work at the moment. To better analyze the problem it would be helpful if we could see how many such queries happened on a server. Is there a counter or a statistic which can provide us this information? We use MariaDB 5.5. Cheers, Shorty

[Maria-discuss] start mariadb randomly fails or answers with wrong response to systemd
by Reindl Harald 20 Jan '14

20 Jan '14

i have for at least 5 years a backup server with two mysql-instances * one replication instance listening on port 3307 * one "live" service * a script once a hour stop both instances and rsync replication->live * after that start both intances again * looking at the mysqld logs i am pretty sure there is nothing wrong and only the non.zero response causes systemd to restart the daemon one time well, with MariaDB on Fedora 19 systemd cries about failing service at the same time there is nothing in the mysql-errorlog (both instances using the same) the systemd-units are configured to restart the daemon again if it fails what replaces the mysqld_safe scripts and is done this way unchanged since summer 2011 with MySQL 5.5.x has anybody an idea what causes the "mysqld.service" instance to respond with status 1 instead 0 causing systemd to consider the service as failed while there is nothing uncommon in the mysqld-logs? the "Error reading relay log event: slave SQL thread was killed" as well as "Error reading packet from server" are not relevant in that context because they are from the not failing "replication.service" and normal due shutdown the slave (well, i dislike "error" in that context, but that's OT) interesting is that i have 3 machine-pairs with the 100% identical logic two of them are failing this way nearly every hour (backup schedule 60 minutes) while the one with 5000 tables is running perfect all the time any information i could provide additional to the logs and configs below? ___________________________________________________________________________ Jan 7 20:21:04 localhost backups: stop replication service Jan 7 20:21:04 localhost systemd[1]: Stopping MySQL Replication...

[Maria-discuss] New Question: MariaDB Galera Cluster Questions
by AskMonty KB 04 Jan '14

04 Jan '14

Hello, A new question has been asked in "MariaDB FAQ" by pranava: -------------------------------- I have some questions on Maria DB Galera Cluster. Q1) If I partition a table in a schema which is part of MariaDB Galera Cluster, can i configure partitions in such a way that a one partition resides in one Node, another partition resides in second Node and so on? I'm trying to shard the data and use Galera cluster nodes to accommodate parts of that shard. Q2) Scenario - During replication of MariaDB Galera Cluster, the Master node gets a request, it processes it and then sends to other nodes for approval, followed by a commit at every node. What if commit happens on majority of nodes except one or two? What happens to that transaction and how about Data consistency among all nodes? Q3) Which protocol is used for communicating between nodes during data replication in MariaDB Galera Cluster? Is it TCP or a Broadcast to all other nodes or Some customized protocol between nodes that enables replication in the cluster. Thanks a lot in advance. Thanks Pranav. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/mariadb-galera-cluster-questions/

First, some background info about our system 1) ~2000 tables. 3/4th of them are innodb, the rest are myisam 2) All tables are partitioned with ~100 partitions each 3) our largest tables are partitioned (~200 partitions each) and they're all myisam due to space constraints (and other reasons) 4) all our instances are on amazon ec2 on ephemeral store Some of our config parameters open-files-limit 131072 innodb-open-files 16384 table-open-cache 4096 innodb-buffer-pool-size 256M One of the problems we're facing with mysql, and we're hoping to solve with mariadb, is the blowup of the number of open file descriptors when some of our long-running/heavier scripts run. So far we've been able to keep it in control by having our scripts flush at intervals, as well as making individual threads hit different read slaves so as to not open up mulitple copies of myisam fds on a single machine. I do know that the above parameters could be tweaked to set a cap on the number of file descriptors (innodb seems to be a hard limit, so thats under control), but we've set table-open-cache at a high number for performance reasons. Our ideal solution would be to keep the above parameters and not run into a situation where the number of file descriptors grow uncontrollably beyond 70k-80k. It would be preferable to have mariadb close file descriptors once queries are done. We were interested in the mariadb threadpool option as it launches threads dynamically when needed and closes them once it's done. I'm currently testing on a mariadb instance with the default parameters. One of my assumptions with threadpools was that when additional threads were closed, the file descriptors opened for them would also be closed, but upon testing I've seen that this is not the case, and that mariadb behavior as far as threadpools are concerned is exactly the same as mysql. For example, with thread_pool_size=1 and max_threads at 500, if I run 10 identical concurrent queries from different connections on mariadb on a myisam table, it opens up 10 sets of 200 file descriptors. Threadpool_threads spikes up to 10 and drops back down after some time, but all the file descriptors initially opened are still in the open state (2200 fds ). Is this intended behavior for threadpools? I would also be grateful for any tips, reading material or knowledge regarding how mariadb handles file descriptors and if there are any additional parameters that can be tuned to keep the number of file descriptors under control, while not impacting performance too much Thanks in advance.

[Maria-discuss] New Question: Debug files not written by client lib
by AskMonty KB 26 Dec '13

26 Dec '13

Hello, A new question has been asked in "MariaDB Client Library for C" by sruliganor: -------------------------------- Hi, I have a C program that uses mariadbclient.lib. I added this line to generatate a trace file from the lib: mysql_debug("d:t:O,e:\\Temp\\MysqlClient.log"); In addition I set environmant variable MYSQL_DEBUG. However, no debug file was created anywhere. What should I do to see trace files? I tried the client lib 1.0 binary downloaded fron your site, as well as the source code complied in DEBUG. Thanks -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/debug-files-not-written-by-client-lib/

[Maria-discuss] Change from MySQL to MariaDB - Problem with EVENTS-Table in information_schema
by Frank Röhm 20 Dec '13

20 Dec '13

Hello day before yesterday I updated my MySQL Server 5.5.34 to MariaDB 5.5.34 on my Ubuntu 12.04 Server. All went fine but next day, I noticed that the automatic backup script (automysqlbackup) had errors, I read: mysqldump: Couldn't execute 'SELECT /*!40001 SQL_NO_CACHE */ * FROM `EVENTS`': Cannot proceed because system tables used by Event Scheduler were found damaged at server start (1577) mysqldump: Couldn't execute 'show events': Cannot proceed because system tables used by Event Scheduler were found damaged at server start (1577) I searched about it and found the hint to do the command mysql_upgrade (I needed the option --force) and restart the server. This didn't help, no change. When I manually select * from EVENTS from information_schema I get the same error 1577. When I upgraded I made a backup before, so could I just overwrite the existing information_schema with the dump from my backup? Could I destroy something? Thank you. frank

Re: [Maria-discuss] INSERT IGNORE (and other SQL commands) fail with: Deadlock found when trying to get lock;
by Benoit Panizzon 20 Dec '13

Hi > If memory serves me, the first timestamp, will be set > to current universal time. Like db.table.last_changed Ok, I replaced NOW() with a generated timestamp to avoid that NOW() deadlock. sub mysql_now() { my($sec,$min,$hour,$mday,$mon,$year,$wday, $yday, $isdst)=localtime(time); my($result)=sprintf("%4d-%02d-%02d %02d:%02d:%02d",$year+1900,$mon+1, $mday,$hour,$min,$sec); return $result; } [...] my $mysqltimestamp = mysql_now(); my $timestamph = $dbh->prepare("UPDATE user SET lastActive = ". $dbh- >quote($mysqltimestamp) ." WHERE userid = ". $dbh->quote($user) ." and domain = ". $dbh->quote($domain)); $timestamph->execute(); Still in about 1 of 10 updates, this causes that wrenched Deadlock error, causing the email not being processed correctly and in the case the email is not for local but being forwarded, the email is not forwarded to the correct destination. Dec 18 14:12:34 asterix mimedefang-multiplexor[8019]: NOQUEUE: Slave 0 stderr: DBD::mysql::st execute failed: Deadlock found when trying to get lock; try restarting transaction at /etc/mimedefang-filter.mx line 316. Is there any known way to circumvent that Deadlock Problem?
