Jan Lindström	2bf3e416fe	MDEV-6932: Enable Lazy Flushing Merge Facebook commit `4f3e0343fd` authored by Steaphan Greene from https://github.com/facebook/mysql-5.6 Adds innodb_idle_flush_pct to enable tuning of the page flushing rate when the system is relatively idle. We care about this, since doing extra unnecessary flash writes shortens the lifespan of the flash.	11 years ago
Jan Lindström	fc2df3c637	MDEV-6812: Merge Kakao: Add global status variables which tell you the progress of inplace alter table and row log buffer usage - (x 100%, it's 4-digit. 10000 means 100.00%) - Innodb_onlineddl_rowlog_rows Shows how many rows are stored in row log buffer. - Innodb_onlineddl_rowlog_pct_used Shows row log buffer usage in percent ( *100%, it's 4-digit. 10000 means 100.00% ). - Innodb_onlineddl_pct_progress Shows the progress of inplace alter table. It might be not so accurate because inplace alter is highly depend on disk and buffer pool status. But still it is useful and better than nothing. - Add some log for inplace alter table XtraDB/InnoDB will print some message before and after doing some task.	11 years ago
Jan Lindström	df4dd593f2	MDEV-6247: Merge 10.0-galera to 10.1. Merged lp:maria/maria-10.0-galera up to revision 3879. Added a new functions to handler API to forcefully abort_transaction, producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These were added for future possiblity to add more storage engines that could use galera replication.	11 years ago
Jan Lindström	5ebb396638	MDEV-6247: Merge 10.0-galera to 10.1. Merged lp:maria/maria-10.0-galera up to revision 3867.	11 years ago
Jan Lindström	6dad23f04a	MDEV-5834: Merge Kakao Defragmentation implementation to MariaDB 10.1 Merge https://github.com/kakao/mariadb-10.0 that contains Facebook's implementation for defragmentation facebook/mysql-5.6@a2d3a74 facebook/mysql-5.6@def96c8 facebook/mysql-5.6@9c67c5d facebook/mysql-5.6@921a81b facebook/mysql-5.6@aa519bd facebook/mysql-5.6@fea7d13 facebook/mysql-5.6@09b29d3 facebook/mysql-5.6@9284abb facebook/mysql-5.6@dbd623d facebook/mysql-5.6@aed55dc facebook/mysql-5.6@aad5c82 This version does not add new SQL-syntax and new handler API function. Instead optimize table is mapped to defragment table if innodb_defragment=ON, by default the feature is off. Contains changes authored by Sunguck Lee (Kakao).	11 years ago
Jan Lindström	dbc79ce055	MDEV-6354: Implement a way to read MySQL 5.7.4-labs-tplc page compression format (Fusion-IO). Addeed LZMA and BZIP2 compression methods.	11 years ago
Jan Lindström	3e5994868d	MDEV-6392: Change innodb_have_lzo and innodb_have_lz4 as a static variables and reduce the number of ifdef's	12 years ago
Jan Lindström	648fb98eb6	MDEV-6348: mariadb crash signal 11 Analysis: sync array output function, should make sure that all used pointers are valid before using them. Merge revision 4225 from lp:maria/5.5.	11 years ago
Jan Lindström	3bca01930a	MDEV-6361: innodb_compression_algorithm configuration variable can be set to unsupported value. MDEV-6350: Excessive unnecessary memory allocation at InnoDB/XtraDB startup if LZO is installed.	12 years ago
Sergei Golubchik	8eaa1d90a4	use ENUM not ULONG for innodb-compression-algorithm command-line option	12 years ago
Jan Lindström	13c73c31c3	Added support for LZO compression method. Removed: innodb_use_lz4 configuration parameter Added: innodb_compression_algorithm configuration parameter 0 = no compression, 1 = ZLIB, 2 = LZ4, 3 = LZO Fixed issue with incorrect trim calculations	12 years ago
Jan Lindström	3ea72a2ba9	Removed options innodb_compress_index_pages and innodb_trim_pct. Both are unnecessary. There is a lot more index pages than there is normal pages. Earlier all pages were compressed and this provided best performance and compression ratio. Added status variable to show how many non index pages are written.	12 years ago
Jan Lindström	4e02c2fe56	MDEV-5335: Force PK option. Added a new dynamic configuration variable innodb_force_primary_key default off. If option is true, create table without primary key or unique key where all keyparts are NOT NULL is not accepted. Instead an error message is printed. Variable value can be changed with set global innodb_force_primary_key = <value>.	12 years ago
Jan Lindström	c556b9d817	Changed so that innodb_compress_index pages means that if true also index pages are compressed if false index pages are not compressed. Fixed small output error when page_compression_level was incorrectly given.	12 years ago
Jan Lindström	3a4b8879e5	Set index page page compression on by default and remove innodb_trim_pct as it is not used/implemented.	12 years ago
Jan Lindström	b67892cf59	Turn all new features off by default.	12 years ago
Jan Lindström	c88a0d48c6	Temporal fix for flush thread hang. Added option to disable multi-threaded flush with innodb_use_mtflush = 0 option, by default multi-threaded flush is used. Updated innochecksum tool, still it does not support new checksums.	12 years ago
Jan Lindström	d17ecff410	Fixed issue on data dictionary corruption. Fixed issue on multi-threaded flush at shutdown. Removed unnecessary startup option innodb_compress_pages. Added a new startup option innodb_mtflush_threads, default 8.	12 years ago
Jan Lindström	a5cf3a800e	Merged latest mt-flush code to xtradb. Cleaned up thread statistic output code.	12 years ago
Jan Lindström	8c5d5bc5de	Fixed merge error on InnoDB page compression level handling. Merged page compression feature to XtraDB storage engine. Added feature where page compression can use lz4 compression method (innodb_use_lz4, default OFF).	12 years ago
