[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
by Roberto Spadim 25 Sep '14

25 Sep '14

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

[Maria-discuss] OQGRAPH and query cache
by Roberto Spadim 24 Sep '14

24 Sep '14

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
