Merge Facebook commit ca40b4417fd224a68de6636b58c92f133703fc68 authored by Steaphan Greene from https://github.com/facebook/mysql-5.6 Change the default value for innodb_log_compressed_pages to false Logging these pages is a waste. We don't want this to be enabled. One caution here: If the zlib version used by innodb is changed, but the running version is still the previous version, and the running version crashes, it is possible crash recovery could fail. When crash recovery uses a zlib version at all different than the version used by the crashed instance, it is possible that a redone compression could fail, where the original did not, because the new zlib version compresses the same data to a slightly larger size. Because of the nature of compression, this is even possible when upgrading to a version of zlib which actually peforms overall better compression than the previous version. If this happens, mysql will fail to recover, since a page split can not be safely triggered during crash recovery. So, either the exact zlib version must be controlled between builds, or these rare recovery failures must be accepted. The cost of logging these pages is quite high, so we consider this limitation to be worthwhile. This failure scenario can not happen if there was a clean shutdown. This is only relevant to restarting crashed instances, or starting an instance built via a hot backup too (XtraBackup). |

VERSION |
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 file CREDITS 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 MariadB foundation and SkySQL Ab, 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 do 'SHOW authors' to get a list of active contributors. A description of the MariaDB project and a manual can be found at: http://mariadb.org/ https://mariadb.com/kb/en/ 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. More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss and the #maria IRC channel on Freenode. *************************************************************************** NOTE: MariaDB is specifically available only under version 2 of the GNU General Public License (GPLv2).
