[Maria-discuss] MariaDB for OpenSuSE 12.3
by Peter Laursen 06 Dec '14

06 Dec '14

I have OpenSuSE 12.3. It ships with MariaDB 1.0.13 - and with no TokuDB and no Galera options. I would like to upgrade to 10.0.14 and also enable TokuDB. And it does not seem that an upgrade will be available from SuSE software repositories. There are a lot of RPMs in the yum repository http://mirror.23media.de/mariadb/mariadb-10.0.14/yum/. But does anyone know if they will work with SuSE 12.3? Runtime environment (kernel, glibc etc.) should be compatible of course, and also RPMs for Redhat/Fedora/CentOS systems will not alwyas work on SuSE, as SuSE has some specific requirements for the SPECS. When I used SuSE 10.x many years ago, the generic "glibc23" RPMs available worked perfectly. Note: I *only* want to install a server that can be handled by SuSE's YaST package manager! So suggestons for any other solution (such as using the tarball) is not an option. Or it would be last resort. I would not mind give it a try if someone can advise what I should try. I have SuSE running in a VM and I will be able to return to a snapshot of the system easily if something goes wrong. -- Peter

[Maria-discuss] new mdev about better explain

Hi guys, any help is wellcome here the problem: why optimizer chose a "bad" index? an example about this problem is MDEV-7125 i have this EXPLAIN output: id|select_type|table|type|possible_keys|key|key_len|ref|rows|Extra 1|SIMPLE|c|const|PRIMARY,NewIndex|PRIMARY|265|const,const|1|Distinct; Using temporary 1|SIMPLE|b|range|PRIMARY,id,plano_conta_numero,cod_busca|cod_busca|265|(NULL)|49|Using index condition; Distinct *1|SIMPLE|a|ref|cfop,item,transferencias,rendimento,estoque,giro|item|6|const,19_org.b.plano_conta_id_red|3347|Using where; Distinct* 1|SIMPLE|d|eq_ref|PRIMARY,NewIndex|PRIMARY|265|19_org.a.estoque_entrada_org,const|1|Using index condition; Using where; Distinct --- check the row from table "a" 1|SIMPLE|a|ref|*cfop,item,transferencias,rendimento,estoque,giro*|item|6|const,19_org.b.plano_conta_id_red|3347|Using where; Distinct optimizer found 5 possible index, and chose the "item" index, instead of "rendimento" index, it's not the best index, but i don't know why optimizer prefer "item" instead of "rendimento" to "solve" (explain) this optimizer choise i execute force index in each index and get output from explain... example EXPLAIN SELECT ... FROM est_mov AS a FORCE INDEX (cfop) ... EXPLAIN SELECT ... FROM est_mov AS a FORCE INDEX (item) ... EXPLAIN SELECT ... FROM est_mov AS a FORCE INDEX (transferencias) ... EXPLAIN SELECT ... FROM est_mov AS a FORCE INDEX (rendimento) ... EXPLAIN SELECT ... FROM est_mov AS a FORCE INDEX (estoque) ... EXPLAIN SELECT ... FROM est_mov AS a FORCE INDEX (giro) ... and compare each output to know why it chose the index 'item' as 'best' option could be possible a better explain from optimizer? something like { 'item': {'key_len':1234, 'ref rows':'blablalba', 'filtered' 99, 'extra':'blabla'}, 'transferencias': {'key_len':1234, 'ref rows':'blablalba', 'filtered' 99, 'extra':'blabla'}, 'rendimento': {'key_len':1234, 'ref rows':'blablalba', 'filtered' 99, 'extra':'blabla'}, 'giro': {'key_len':1234, 'ref rows':'blablalba', 'filtered' 99, 'extra':'blabla'} } i don't know if optimizer have this information, but it's relevant? could we implement a better explain? what others users (dba/developer) do when they have this problem (optimizer selecting the wrong index)? thanks guys -- Roberto Spadim SPAEmpresarial Eng.

[Maria-discuss] MariaDB 10.1 uses huge amount of memory onWndows
by Peter Laursen 23 Nov '14

23 Nov '14

Please see attached imaged - a screenshot of Windows Task manager. I have a lot of MySQL and MariaDB servers installed (all needed for application testing). It is noticeable that MariaDB 10.1 uses around twice as much as much memory as compared to MariaDB 10.0, MySQL 5.6 and 5.7 (5 GB versus 2.5 GB in rough numbers). Even more surprising to me as P_S is not running with 10.1 (as I understand). Further I have MariaDB 10.0 running virtualized in OpenSuSE 12.3 inside Virtualbox. The process for the virtual machine use only around 10% or memory as compared to MariaDB 10.0 running natively on Windows (there is also an active VM running Mint Linux - but MySQL is not running there currently) I also have a number of older MySQL servers (5.0, 5.1 and 5.5) The use much less memory. That is expected as the configuration reserves smaller buffers. Both MariaDB servers in Windows use the configuration created by the installer. MySQL 5.6 adn 57 servers use the MySQL Installer standard "developer machine" configuration. The configuraiton of MariaDB 10 in SuSE is as shipped with the distro (I did not check it actually). None of the servers have been connected to since system was restarted. System has been running for approximately 4 hours and all servers start with Windows. The VM with SuSE has been running for approxmately 2 hours. In the attached image I have framed and starred my observations. I want to emphatize, that I don't face any problems with this at all. I have 32 GB RAM and 4 CPUs each capable of processing 2 parallel threads,and I can run Windows 7 with all the servers you see (and simultaneously use the system iinteractively for Internet browsing, playing media, processing photos, document creation/editing and what else you would do with a desktop system), as well as have the two VMs (both configured with an upper resource limit of 24 GB RAM and 6 CPU threads). The memory may be released if it is required by other processes. I don't think it is a problem to use memory if it is available if it will be released when it is required elsewhere (on the opposite it was a little expensive, so it would be a shame if it was not used at all!) But still I find the find the MariaDB 10.1 number for memory use so much *off* as compared to comparable servers, that I think I should mention the observation here. IMO it should be understood **why** it happens and next it can be decided **if** a fix is necessary or not. -- Peter -- Webyog

Good morning, Is there a way to have MariaDB run in-memory? I mean, without changing the table engines. I have my production code which needs to be persisted to disk, but for my unit tests, it would be great to have an in-memory DB. I'm in the Java world and I've tried HSQLDB but its SQL implementation is way too different than that of MariaDB. Any ideas?

When I perform join on both the table and perform the sort on the column which is not main table it is behaving really slow. I have tested with 8 GB RAM. Whole database fits in memory. I have also checked with EXPLAIN it is not creating temporary table on disk. How can I get best performance? e.g query. SELECT DISTINCT u0_.id AS id_0, a1_.created_at AS created_at_1 FROM user u0_ LEFT JOIN advertise a1_ ON (a1_.user_id = u0_.id) ORDER BY a1_.created_at DESC LIMIT 10; Also note that all the indexes are properly created so that is not he issue here. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/mariadb-sorting-issue/

Please answer it at http://mariadb.com/kb/en/mariadb-configuration-file-license/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hi, Are the default MariaDB configuration files licensed under GPL, or is there a more permissive license for it? The context of my question... I am a committer on the apache Brooklyn project [1]. This automates the deployment and runtime management of applications to a range of different clouds. MariaDB can be one of a range of components being deployed and wired together. We have copied the my.cnf configuration file, and templated it so that automated deployment of custom configurations are simpler. However, Apache does not allow inclusion of GPL/LGPL material [2]. We may have to write our own version of the configuration file from scratch, or delete our templated version and resort to `sed` commands to modify the default (yuck!).

To get that to work again we need to have new views build in Sybase and since we dont own the Sybase database that is crazy expenciv. So we thought about using MariaDB as a middleware and store data from Sybase in it and use that instead as data source for our directory. So my question is if it's possible in MariaDB to run a query that reads data from a Sybase DB and store the result?

[Maria-discuss] question regarding innodb compression
by Rohan M C 03 Nov '14

03 Nov '14

Hi all, Due to space constraints we are considering the innodb compression option for some of our larger tables. We're not compressing all the tables, but only a select few to begin with. Our current planned process for this is to SET GLOBAL innodb_file_format=Barracuda; create compressed table, transfer data, and switch innodb_file_format back to Antelope. My question is around having this mix of table file formats in the same database. I've tried test queries and they were fine, but is it ok to have a mix of both Antelope and Barracuda file format tables in the db for a production environment? Thanks, Rohan

Since I had a few issues with it thought I would provide some information for those who are trying to install and help whoever is responsible for the Maria Repository. First, I was successful using the Centos 6 10.1 package via Yum with this repository setting pulled from Mariadb Repository setup. # MariaDB 10.1 CentOS repository list - created 2014-10-29 14:33 UTC # http://mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.1/centos6-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1 Using "yum clean all" and yum update the following packages installed successfully. Shown in this pastebin http://pastebin.com/SMqECaju I did find though that with 10.0 using both the Centos 6 & 7 packages there is an issue with the language error files between MariaDB-server-10.0.14-1.el7.centos.x86_64 and dependency mariadb-libs-1:5.5.37-1.el7_0.x86_64 http://pastebin.com/CSri8mq0 I hope this information helps someone else and possibly the listing of a 10.1 Centos 7 package in the MariaDB Repository. ~Blake

[Maria-discuss] Storage engines enabled by default - MySQL 5.6 vs. MariaDB Galera Cluster 10.0
by Geoff Montee 29 Oct '14

29 Oct '14

I've been building MySQL 5.6 from source for a while. I recently started testing MariaDB Galera Cluster 10.0. When I build MariaDB Galera Cluster from source, I originally used the same cmake flags that I used for MySQL 5.6, along with the additional flags specified in Codership's documentation: http://galeracluster.com/documentation-webpages/installmariadbsrc.html My build process basically comes down to this: cmake . -L -DCMAKE_INSTALL_PREFIX=$MYQL_PREFIX -DMYSQL_DATADIR=$MYSQL_DATA -DWITH_SSL=yes -DWITH_READLINE=ON -DWITH_PIC=ON -DWITH_UNIT_TESTS=0 -DWITH_WSREP=ON -DWITH_INNODB_DISALLOW_WRITES=1 make make install With MariaDB Galera Cluster 10.0.14, the server that gets built does not have the Archive and Blackhole storage engines enabled by default. I do see that "ha_archive.so" and "ha_blackhole.so" were built and placed in plugin_dir, so I could probably enable them manually with INSTALL PLUGIN. This surprised me, because these engines are enabled by default in MySQL 5.6, and I see no mention of this difference here: https://mariadb.com/kb/en/mariadb/mariadb-vs-mysql-compatibility/#incompati… Of course, if I add "-DWITH_ARCHIVE_STORAGE_ENGINE=ON -DWITH_BLACKHOLE_STORAGE_ENGINE=ON" to my cmake arguments, then these engines are enabled in the MariaDB server that gets built. Is this difference intentional? If so, you may want to add a note to the documentation referenced above. If it's an unintentional discrepancy, I can submit a bug report on JIRA. Thanks, Geoff

[Maria-discuss] Dots in filenames of configuration files - !includedir weirdness
by Geoff Montee 24 Oct '14

24 Oct '14

I've noticed some strange behavior that might be a bug in the current implementation of the !includedir directive for my.cnf files. I wanted to get the opinion of the MariaDB community on whether this is working as intended before reporting it. Let's say I have a line like the following in /etc/my.cnf: !includedir /home/mysql/conf MariaDB should load any configuration variables from files with the extension ".cnf" in that directory. The problem I ran into is that MariaDB appears to determine the extension based on the first dot ('.') in the filename. If I have a file with a full path like this: /home/mysql/conf/mariadb10.0-galera.cnf MariaDB appears to think that the extension of the file is 0-galera.cnf, so it won't load it. If the file is renamed to something like this (with no extra dots): /home/mysql/conf/mariadb10-0-galera.cnf MariaDB properly loads the configuration file. Is this a bug that should be reported? System info: OS: RHEL 6 Arch: x86_64 MariaDB build: MariaDB Galera Cluster 10.0.14, built from source Slightly related note: I don't see any documentation on the !includedir directive in the MariaDB knowledgebase. I would expect to see some mention of it here: https://mariadb.com/kb/en/mariadb/documentation/getting-started/configuring… Thanks, Geoff Montee

[Maria-discuss] New Question: Cluster Overall Memory Requirements (compared to multiple stand-alone nodes)
by AskMonty KB 21 Oct '14

21 Oct '14

Hello, A new question has been asked in "Galera" by getreal: -------------------------------- Maybe I'm just missing it somewhere on the site, but I'm trying to find a way to contrast overall memory requirements for a Galera cluster compared to that of stand-alone mySQL instances. In my profession we build servers that are typically 32GB overall memory running an instance of mySQL within, in which we hand 16GB to innodb_buffer_pool_size (the actually size of the mySQL database files is upwards of four times that). The server does other things by the way (a 6 GB JVM is also loaded). Our buffer pool hit rate is typically a nice high number (over 99%) with that 16GB allocated. So let's take a simple scenario - 6 of my stand-alone servers are going to evolve to MariaDB + Galera cluster. I completely realize we need 3 nodes minimum on the Galera side, and I realize we now are accommodating about 6 x 64GB of former mySQL database files (as long as we presume the database files overall size in mariaDB is about the same as that of mySQL). So I've got 384 GB of database f iles, and let's suppose I want to replace this with a 3 node mariaDB+Galera cluster. I know that 384 GB has to be replicated amongst those three nodes, storage sizing is not so complex, and I know I can probably get enough CPU under these node with 4 vCPUs. But my question is more so around innodb_buffer_pool size for each node. Do I need to run 6 x 16 GB = 96 GB for innodb_buffer_pool_size in each node of that Galera cluster (essentially the same ratio 1:4 as I did in mySQL instances with my stand-alone servers) ? Any help appreciated. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/cluster-overall-memory-requirements-compared-to-mu…

[Maria-discuss] New Question: field looks weird using select *
by AskMonty KB 19 Oct '14

19 Oct '14

Hello, A new question has been asked in "MariaDB Documentation" by martyheitzmann: -------------------------------- I just started using mariadb. I created two tables so far : the first one - no issues. But, when I try to select * from the 2nd table, the primary key field looks incomplete: +--------+--------+---------------+----------------+ | teamid | league | teamname1 | teamname2 | +--------+--------+---------------+----------------+ | | A | Anaheim | Angels |ARI | N | Arizona | Diamondbacks | | N | Atlanta | Braves | | A | Baltimore | Orioles | | A | Boston | Red Sox | | A | Chicago | White Sox | N | Chicago | Cubs ... (look past the copy/paste formatting issues please) The teamid column is not printed out for every teamid, and based on the '|' separator, it looks like the field has different lengths, but it's just a char(3) fixed-length. I tried defining the field as nvarchar(3), and char(3), with the same results. I thought it had to do with the file from which the data was imported, but it contains no control characters. It's a ':' separated field that looks like: ANA:A:Anaheim:Angels BAL:A:Baltimore:Orioles BOS:A:Boston:Red Sox CHA:A:Chicago:White Sox ... file imported using : LOAD DATA INFILE '<file>' INTO TABLE Tteams FIELDS TERMINATED BY ':'; thoughts? -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/field-looks-weird-using-select/

[Maria-discuss] New Question: Historical data, nightly snapshots
by AskMonty KB 17 Oct '14

17 Oct '14

Hello, A new question has been asked in "MariaDB Documentation" by bjquinn: -------------------------------- I have an application where I need to take nightly snapshots of a large InnoDB database (10s of GB) and then have them available to be queried alongside the current data. My underlying filesystem is (or at least can be) ZFS, so actually creating the snapshots is easy enough. But how do I connect to the files contained in the snapshot so that I can query the tables via MariaDB? If it's easier through another storage engine, I could consider that, though I do need row locking in the current data. The historical data would be read only (obviously) and wouldn't need to be changed. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/historical-data-nightly-snapshots/

[Maria-discuss] Aborted connection (Unknown error)
by Florent Bautista 15 Oct '14

15 Oct '14

Hi all, I'm getting annoying errors when I want to switch clients from MySQL to MariaDB. I use Debian Wheezy, and MariaDB 10.0 repositories, then I install mariadb-common & libmariadbclient. Then I restart services using MySQL Client Library and I have a lot of warnings like these on my MariaDB Server (with Galera or not) : [Warning] Aborted connection 136305 to db: 'db' user: 'user' host: 'xx.xx.xx.xx' (Unknown error) I do not have more information in logs. This is not a network problem, because it occurs with 127.0.0.1 too. What do I miss ? Thank you a lot. Florent

Should I ask to the Mariadb dev team or the Tokutek dev team (or SanDisk/FusionIO dev team ?) to add it (maybe it’s technically no doable ?)? I would start from Tokutek dev team, I do not know fully how database tables are stored on Tokutek, but I do not see immediately a reason why atomic writes would not be possible. Do you think this can boost performances for huge TokuDB tables ? Atomic will boost performance but only if database is stored on device that supports atomic writes. R: Jan

[Maria-discuss] Possible? upgrading gallera cluster without service interruption
by Benoit Panizzon 30 Sep '14

30 Sep '14

Hello We would like to upgrade from 5.5.33a+maria-1~saucy to 5.5.39+maria-1~saucy on a running cluster without service interruption. So we took down one node, upgraded and restarted that instance... It fails to connect to the next gcomm server. MariaDB fails to start. We tested network connectivity, there is no issue we could detect. We downgraded back to 5.5.33a+maria-1~saucy and the connectivity issue disappeared. So my question here is: Is it possible to upgrade the cluster without interruption, or do we have to shut the whole cluster down, upgrade every node and then restart everything? Kind regards Benoit Panizzon -- I m p r o W a r e A G - ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 07 CH-4133 Pratteln Fax +41 61 826 93 02 Schweiz Web http://www.imp.ch ______________________________________________________

Hi Christophe, This is Dhananjoy Das (Joy) from SanDisk (formally Fusion-io inc.,) contributor to the NVM Compression. In regards to your query on access to NVMFS, yes currently its supported on Atomics Series of ioMemory cards(PX/SX), I would suggest its best to get in touch with the SanDisk Sales team (formally Fusion-io inc.,) and request for the LA NVMFS 1.0 (Limited Edition). Additionally, NVM Compression (changes are part of InnoDB/XtraDB) is independent of the TokuDB DB-engine. Hope that help, feel free to reach out.

[Maria-discuss] MariaDB,TokuDB and FusionIO
by Christophe Le Roux 26 Sep '14

26 Sep '14

Hello, After reading the previous discussion about Fusion IO with Torben Mathiasen contribution, I have some questions. I understand that the nvmfs is developed by FusionIO and is closed source. Can we have this module (I think it's a kernel module , right ?) if we buy a new FusionIO card (Only with Atomic Series?)? Is this module ok with "old" FusionIO card (iodrive2) ? About AtomicWrites and the NVM compression, can these features be added to the TukuDB engine ? Can the TokuDB compression and the NVM compression be working together or if we enable one, we need to disable the other ?

[Maria-discuss] Partitions and query cache

Guys new doubts about partition and query cache drop table t1; reset query cache; CREATE TABLE t1 (c DATETIME) PARTITION BY HASH ( YEAR(c) ) partitions 4; *using myisam engine insert into t1 values ('2014-01-01'),('2013-01-01'),('2012-01-01'),('2011-01-01'),('2010-01-01'); select * from t1; select * from t1 partition (p0); select * from t1 partition (p1); select * from t1 partition (p2); select * from t1 partition (p3); --- this return: || *QUERY_CACHE_ID* || *SCHEMA* || *TABLE* || || 1 || teste || t1 || || 2 || teste || t1 || || 3 || teste || t1 || || 4 || teste || t1 || || 5 || teste || t1 || --- now using innodb: --- alter table t1 engine=innodb; select * from t1; select * from t1 partition (p0); select * from t1 partition (p1); select * from t1 partition (p2); select * from t1 partition (p3); select * from information_schema.QUERY_CACHE_QUERIES_TABLES; --- this return: || *QUERY_CACHE_ID* || *SCHEMA* || *TABLE* || || 1 || teste || t1 || || 1 || teste || t1#P#p0 || || 1 || teste || t1#P#p1 || || 1 || teste || t1#P#p2 || || 1 || teste || t1#P#p3 || || 2 || teste || t1 || || 2 || teste || t1#P#p0 || || 2 || teste || t1#P#p1 || || 2 || teste || t1#P#p2 || || 2 || teste || t1#P#p3 || || 3 || teste || t1 || || 3 || teste || t1#P#p0 || || 3 || teste || t1#P#p1 || || 3 || teste || t1#P#p2 || || 3 || teste || t1#P#p3 || || 4 || teste || t1 || || 4 || teste || t1#P#p0 || || 4 || teste || t1#P#p1 || || 4 || teste || t1#P#p2 || || 4 || teste || t1#P#p3 || || 5 || teste || t1 || || 5 || teste || t1#P#p0 || || 5 || teste || t1#P#p1 || || 5 || teste || t1#P#p2 || || 5 || teste || t1#P#p3 || Now my question... Why ha_partition don't use the right partition at query cache? this give a new problem of query cache partition prune, update t1 set c='2009-01-01' where c='2012-01-01'; after this i have no query at query cache the problem is instead of remove partition #p0 (2012) and #p1 (2009), it removed all partitions from query cache that's the right thing to do? maybe we should check ha_partition and query cache? -- Roberto Spadim

Hi guys, i was reading docs, and found this: - The query cache needs to be disabled in order to use OQGRAPH <https://mariadb.com/kb/en/oqgraph/> and, in older versions, Galera <https://mariadb.com/kb/en/galera/>. Why query cache needs to be disabled with OQGRAPH? -- Roberto Spadim SPAEmpresarial Eng. Automação e Controle

[Maria-discuss] transactions and UNLOCK TABLES
by Federico Razzoli 23 Sep '14

23 Sep '14

In this MySQL manual page: http://dev.mysql.com/doc/refman/5.6/en/implicit-commit.html I read: "UNLOCK TABLES commits a transaction only if any tables currently have been locked with LOCK TABLES to acquire nontransactional table locks." However, this doesn't seem to be the case, at least with MariaDB 10.0: MariaDB [test]> CREATE OR REPLACE TABLE m (c INT) ENGINE = InnoDB; Query OK, 0 rows affected (0.39 sec) MariaDB [test]> CREATE OR REPLACE TABLE t (c INT UNIQUE) ENGINE = InnoDB; Query OK, 0 rows affected (0.54 sec) MariaDB [test]> SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; Query OK, 0 rows affected (0.00 sec) MariaDB [test]> START TRANSACTION; Query OK, 0 rows affected (0.00 sec) MariaDB [test]> INSERT INTO m VALUES (1); Query OK, 1 row affected (0.00 sec) MariaDB [test]> INSERT INTO t VALUES (1); Query OK, 1 row affected (0.00 sec) MariaDB [test]> UNLOCK TABLES; Query OK, 0 rows affected (0.00 sec) MariaDB [test]> SELECT @@in_transaction; +------------------+ | @@in_transaction | +------------------+ | 1 | +------------------+ 1 row in set (0.00 sec) -- So, could you please confirm that UNLOCK TABLES is transaction-safe? If it isn't, could someone please explain in which cases it isn't? Regards Federico

[Maria-discuss] nosql and mysql
by Roberto Spadim 21 Sep '14

21 Sep '14

Guys, today i use some others solutions like redis memcache mongo, etc they are nosql database/cache, and we have handler socket with innodb in mariadb that i use too The question is... i always have problem with security since some of them don't have login security, ssl, etc... I know that's possible, but what's the pros/cons about including others parsers/optimizer inside mariadb code? what i'm saying? something at client side like: mysql_connect() mysql_query("sql query") while(mysql_fetch()){ something... } mysql_free() but instead of sql we could execute nosql, like: mysql_connect() mysql_query("some handler socket/memcached get","parser = handler socket/memcached") or mysql_parser("handler socket/memcached") mysql_query("some handler socket/memcached get") while(mysql_fetch()){ something... } mysql_free() what i see as pros/cons; pros: only one protocol with auth/security, less cpu/memory consume? less software to take care, understand, update, easier integration between daemon plugins and mysql tools, single point of configuration cons: one single point of failure, time to develop, integrate with mysql server (since we need changes to mysql protocol) what you think? -- Roberto Spadim
