Problem: Server throws OOM error when we execute twitter load with SELECTs for UPDATE + UPDATES, and SELECT queries on tables with full-text index. FTS cache->total_memory store count of total memory allocated to FTS cache (for all fulltext indexes on a table). For each word in fts cache, we store doc-id & word position in a node->ilist. we increment cache->total_memory with size of doc-id & word position whereas we allocate ilist in chuck of 16, 32 ,64 bytes or 1.2 times of last size. When we wil insert huge amount of data into the FTS aux index tables then collectively these small chucks for each token become huge unaccounted memory allocated for FTS cache. Fix: Incremented cache->total_memory by size of chunk allocated to node->ilist. RB: 25286 Reviewed by : Rahul Agarkar <rahul.agarkar@oracle.com> mysql/mysql-server@7ab5707f1c |

MariaDB: drop-in replacement for MySQL
MariaDB is designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Foundation and the MariaDB Corporation, and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:
https://mariadb.com/kb/en/mariadb-vs-mysql-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/
As MariaDB is a full replacement of MySQL, the MySQL manual at http://dev.mysql.com/doc is generally applicable.
Help:
More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss and the #maria IRC channel on Freenode.
