Please answer it at http://mariadb.com/kb/en/mysqld-fills-tmp-with-file-tmpsql_26be_0mad/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- We have MariaDB CE 10.1.11 running on RHEL. We were loading data and started getting this error in the mysqld.log: 2016-04-22 9:45:54 139696698296064 [Warning] mysqld: Disk is full writing '/tmp/#sql_26be_0.MAD' (Errcode: 28 "No space left on device"). Waiting for someone to free space... (Expect up to 60 secs delay for server to continue after freeing disk space) We moved the large file out of /tmp, but had to reboot in order to free up the /tmp. Restarted mysqld and it appears to be OK.

[Maria-discuss] GTID replication and SST method
by Craig Bailey 22 Apr '16

22 Apr '16

Hi, I am attempting to get remote replication working from my MariaDB Galera Cluster in the following way: * MariaDB Galera Cluster replicates to a remote MariaDB DR node via standard master slave method using MariaDB GTID o Pick a master node from the cluster o Take a backup with xtrabackup-v2 o Apply backup to slave o Connect the slave to the master and replicate using MariaDB GTID o If master goes down, switch master to another node in the Galera Clutser However I am having problems keeping the GTID in step across all the nodes in the Galera cluster when joining new nodes or re-joining existing nodes. Using the latest version of xtrabackup-v2 the current GTID position is stored in a file as part of the backup, however it does not apply this value to the database when a node is brought into the cluster. A step by step example is below: * Cluster is running fine * Lots of transactions going through, enough that a new joiner would need an SST * Begin joining a new node to the cluster * SST via xtrabackup-v2 happens during this process * The GTID in the donor is 1-1-12345 * SST completes joiner is now part of the cluster * The GTID on the newly joined node is 1-1-1 * We now have an out of sync GTID meaning we cannot simply switch master if our current master goes down. I tried the same scenario using RSYNC as the transfer method and the GTID is replicated across to the joiner without issue. Ideally I would like continue using xtrabackup-V2 as my SST method because it does very little locking on a state transfer. That being the case are there any work arounds for this, such as a way to ensure the GTID is set on the joiner when the SST happens with xtrabackup-v2? On the MariaDB pages it does say "xtrabackup-v2 and xtrabackup SST methods currently do not support GTID" is this up-to-date information? https://mariadb.com/kb/en/mariadb/galera-cluster-system-variables/#wsrep_ss… Thanks, Craig Evertz UK cbailey(a)evertz.com<mailto:cbailey@evertz.com> www.evertz.com This e-mail and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

[Maria-discuss] Dynamically rewrite query
by Erik Cederstrand 21 Apr '16

21 Apr '16

Hello list, I'm administering a MariaDB (10.0.23) backend used by some proprietary software. I'm having trouble with one specific slow query. The tables look like this (simplified for clarity): CREATE TABLE `t1` ( `i` int(11) NOT NULL, `j` int(11) NOT NULL, `l` int(11) NOT NULL, `m` int(11) DEFAULT NULL, PRIMARY KEY (`i`,`j`,`l`) ); CREATE TABLE `t2` ( `i` int(11) NOT NULL, `k` int(11) DEFAULT NULL, PRIMARY KEY (`i`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; The problematic query is this: SELECT DISTINCT t2.i, t2.k, t1.j, t1.l, t1.m FROM t2 LEFT JOIN t1 ON t2.i=t1.i WHERE t2.k < 123; The query is slow because the DISTINCT clause forces the query to use a temporary table. Removing DISTINCT makes the query 100x faster. Now, since (t1.i, t1.j, t1.l, t1.m) are guaranteed to be unique (and also (t2.i, t2.k) on their own, if the left join doesn't match), I cannot see how "SELECT ..." and "SELECT DISTINCT ..." can possibly produce different output. So I mention that to the developers of said software, and they reply that they forgot why they added the DISTINCT but that they decided it's too risky to remove it (thereby admitting that they don't comment their code, and don't write unit tests for bugs they find, but I knew that already). I'm aware of "Garbage in, garbage out", but it could also be argued that MariaDB should be smart enough to detect that the DISTINCT is unnecessary and ignore it (should I create a bug report for that?). In the meantime, is there any way I can rewrite queries like this dynamically to remove the DISTINCT clause? MySQL 5.7 documentation mentions query rewrite plugins, but I don't see that mentioned in MariaDB documentation. Any other suggestions are welcome. Thanks, Erik

Re: [Maria-discuss] Mariadb 10.1.13 slow stored procedures
by Federico Razzoli 19 Apr '16

19 Apr '16

I don't think that this is a procedure performance problem. The problem seems to be character set conversion. 1) set correctly your server and databases default character set and collation (show variables like '%char', alter database) 2) if your connection uses utf8, and your query/procedures contains a 'string', MariaDB considers 'string' as a utf8 string. Make sure you're using latin1 (with the commant-line client it's the default) To check if the character set is latin1, you can query information_schema.ROUTINES table and check the fields CHARACTER_SET_CLIENT, COLLATION_CONNECTION, DATABASE_COLLATION (or SHOW CREATE PROCEDURE).

The procedeure is a function and returns a double. When I run this in a client (heidiSQL) it takes between 1 minute and 13 seconds (slowest) to 40.451 seconds (fastest) When I change the where clause to read:- WHERE tblsub.criteria1= NAME_CONST('refnum',_latin1'S000730128000' COLLATE 'latin1_swedish_ci') and tblmain.criteria2<5; The query takes 0.078 seconds (slowest) 0.045 (fastest) The following system character set variables are set to “latin1” but stored procedures still try and convert where criteria or passed in parameters to ‘utf8’ Character_set_client Character_set_connection Character_set_database Character_set_results Character_set_server All local tables are InnoDB with latin1_swedish_ci default collation therefore I assume they are stored using the latin1 character set. Is there any way to force MariaDB to use latin1 in stored procedures? Also I must point out that this is happening in MariaDB 10.1.7 and 10.1.13 that I’ve tested but does not happen in MariaDB 5.3.4 which has been my production version since 5.3.4 was released and I must add it has never failed. I’m trying to upgrade to 10.1.xxx to take advantage of the connect engine which I have tested for several months now and found to be extremely useful. However I can not put version 10.1.xxx into service until this issue is sorted.

[Maria-discuss] HikariCP + searching archives
by Stu Smith 19 Apr '16

19 Apr '16

Hello, I'm curious if there is a way to search the archives for this list - I couldn't find one, so I think I'm about to ask a simple question, but here goes: I noticed the MariaDB connector/J docs give an example using the HikariCP connection pool. Was there any reason for this? I saw they filed bugs in the mariadb jira, so they have put some effort into working with the community - and they have pretty graphs showing how fast they are. We're not really too worried about optimizing it yet - just adding a connection pool as a best practice kind of thing to a rest service hitting mariadb. Just wanted to make sure there weren't any caveats to using it with connector/J or if it was picked as the example for any particular reason. Also - any thoughts on pooling being a best practice to start off with or an optimization you should put in when you need it, and feel like tweaking pool lifetimes, etc... Thanks! Take care, -stu

[Maria-discuss] R: MariaDb tablespaces?
by Federico Razzoli 18 Apr '16

18 Apr '16

Hi, In current MariaDB versions, InnoDB has 2 types of tablespaces: * system tablespace * per-table tablespace There is a variable called innodb_file_per_table, you can change it at runtime. When a new table is created with innodb_file_per_table=1, the table has its own tablespace (an .ibd file in the database directory, which contains both data and indexes). When a table is created while innodb_file_per_table=0, it is written into the system tablespace. The system tablespace also contains other information, like the InnoDB data dictionary, un logs, etc. I see no particular advantage in creating new tables into the system tablespace - I consider it a feature inherited from old versions, when there were no alternatives. Remembers that the system tablespace never shrinks, even if you drop a table. Also, when using a dedicated tablespace, you can decide where the new table will be placed (see CREATE TABLE options). And you can backup only some tables, if you want to. This also enables table compression and encryption. In MySQL 5.7, you can group multiple tables into one tablespace - which means, not necessarily the system tablespace. From what I see in this page, I think (and hope) and this feature will also be in MariaDB 10.2: https://mariadb.com/kb/en/mariadb/plans-for-10x/ Other storage engines don't have tablespaces: a table is stored in a file (or in 2 files, if data and indexes are stored separately).

[Maria-discuss] Can't find log after Galera's SST
by Igor Mazur 14 Apr '16

14 Apr '16

Hi, Almost everytime when I join node to Galera cluster (MariaDB 10.1.13) I'm getting an error after SST: 2016-04-13 21:09:37 139932281419712 [Note] Recovering after a crash using /var/log/mysql/mariadb-bin 2016-04-13 21:09:37 139932281419712 [ERROR] Binlog file '/var/log/mysql/mariadb-bin.000023' not found in binlog index, needed for recovery. Aborting. 2016-04-13 21:09:37 139932281419712 [ERROR] Crash recovery failed. Either correct the problem (if it's, for example, out of memory error) and restart, or delete (or rename) binary log and start mysqld with --tc-heuristic-recover={commit|rollback} 2016-04-13 21:09:37 139932281419712 [ERROR] Can't init tc log 2016-04-13 21:09:37 139932281419712 [ERROR] Aborting As I see, almost every SST rotates a log file and downloads last (in example above I have mariadb-bin.000024), and not previous. But for recovering it needs previous. Sometimes I'm lucky and it restores. Anyone knows why it rotates a log and is it possible to force it to load more than last log file? Igor Mazur

[Maria-discuss] mariadb/contrib?
by Colin Charles 13 Apr '16

Hi, I was speaking to Hartmut a few days ago and he mentioned that he really did like the idea of postgresql’s /contrib feature. From postgresql/contrib: This subtree contains porting tools, analysis utilities, and plug-in features that are not part of the core PostgreSQL system, mainly because they address a limited audience or are too experimental to be part of the main source tree. This does not preclude their usefulness. (https://github.com/postgres/postgres/tree/master/contrib) Should we consider doing this for MariaDB Server? Have more tools that people might benefit from, but not spend much time on it?

[Maria-discuss] Monitoring InnoDB tables?
by Erik Cederstrand 13 Apr '16

13 Apr '16

Hi list, I'm developing a fast data synchronization tool and need to monitor some tables in a customer's MariaDB (10.1) server for changes. I only have access to the server as a MariaDB client (no filesystem access). Ideally, I would keep a connection open and poll every few seconds - AFAIK, it's not possible for e.g. a stored procedure to notify a listener external to MariaDB. The tables have no 'timestamp' or other columns I can do MAX() on to check for updates. The database is used as a backend for some proprietary software, so I can't just ask the customer to add an autoincrement column. With MyISAM, I could look at UPDATE_TIME in information_schema.tables (and live with the full-second resolution) or ask the customer to "alter table t1 checksum=1;" so I can use "checksum table t1 quick;". None of these work with InnoDB, and "checksum table t1;" is too slow for large tables. I've seen suggestions to use NUM_ROWS and MODIFIED_COUNTER in information_schema.innodb_sys_tablestats, but it's unreliable for me in a number of cases, e.g. if the number of rows is the same but contents are different. Here's an example: MariaDB [test]> create table t1 (i int primary key, j int); Query OK, 0 rows affected (0.02 sec) MariaDB [test]> insert into t1 values (1, 2); Query OK, 1 row affected (0.00 sec) MariaDB [test]> select * from information_schema.innodb_sys_tablestats where name = 'test/t1'; +----------+---------+-------------------+----------+------------------+------------------+------------------+---------+-----------+ | TABLE_ID | NAME | STATS_INITIALIZED | NUM_ROWS | CLUST_INDEX_SIZE | OTHER_INDEX_SIZE | MODIFIED_COUNTER | AUTOINC | REF_COUNT | +----------+---------+-------------------+----------+------------------+------------------+------------------+---------+-----------+ | 15000 | test/t1 | Initialized | 1 | 1 | 0 | 1 | 0 | 1 | +----------+---------+-------------------+----------+------------------+------------------+------------------+---------+-----------+ 1 row in set (0.00 sec) MariaDB [test]> delete from t1; Query OK, 1 row affected (0.00 sec) MariaDB [test]> insert into t1 values (3, 4); Query OK, 1 row affected (0.00 sec) MariaDB [test]> select * from information_schema.innodb_sys_tablestats where name = 'test/t1'; +----------+---------+-------------------+----------+------------------+------------------+------------------+---------+-----------+ | TABLE_ID | NAME | STATS_INITIALIZED | NUM_ROWS | CLUST_INDEX_SIZE | OTHER_INDEX_SIZE | MODIFIED_COUNTER | AUTOINC | REF_COUNT | +----------+---------+-------------------+----------+------------------+------------------+------------------+---------+-----------+ | 15000 | test/t1 | Initialized | 1 | 1 | 0 | 1 | 0 | 1 | +----------+---------+-------------------+----------+------------------+------------------+------------------+---------+-----------+ 1 row in set (0.00 sec) How can I monitor an InnoDB table for changes efficiently? I could *possibly* convince the customer to monitor the binlog or full query log, but then I don't even know which database was changed. The server has hundreds of databases. Erik

I would really appreciate. I believe that some great tools exist but are not used because are not in a default MariaDB/MySQL installation. A contrib directory could advertise good tools and encourage people to try them.
