  7. 7. Today’s Agenda ★ Percona products at 10 000 feet. ★ A closer look at Percona Server with XtraDB. ★ A closer look at XtraBackup. ★ A quick look into the future. ★ Finding more information. 3
  8. 8. Percona Server? 4 Official Oracle Product License MySQL Server GPL/Commercial The InnoDB Storage Engine (Plugin edition) GPL/Commercial InnoDB Hot Backup Commercial Official Percona Product License Percona Server GPL The XtraDB Storage Engine GPL XtraBackup GPL
  9. 9. Percona Server is... ★ A Percona sponsored distribution of the MySQL Server. ✦ Current releases are based on MySQL 5.1. ✦ Earlier releases based on MySQL 5.0 are available. ★ Contains all of the great work of the MySQL engineering team + additional enhancements on top. 5
  10. 10. XtraDB is.. ★ An enhanced version of the InnoDB storage engine. ✦ We ship Percona Server 5.1 with XtraDB included. ✦ You don’t have to download it separately, or do anything special to enable it. ★ XtraDB is based on the “InnoDB plugin”. 6
  11. 11. XtraBackup is... ★ An re-implementation of InnoDB’s hot backup utility. ★ XtraBackup can backup MyISAM, Archive and InnoDB tables. ★ It can backup MySQL, Percona and MariaDB servers. 7
  12. 12. A fork or a spoon? ★ Percona Server and XtraDB are forks by definition. ✦ We change the name to help users identify our distinctively different set of features. ★ Don’t let the word fork scare you. ✦ ~30K lines changed out of millions. ✦ We rebase off newer official MySQL releases. ✦ License remains as GPL (Open Source). ✦ Compatibility is maintained. 8
  13. 13. A word on compatibility: ★ The file format between MySQL with InnoDB to Percona Server with XtraDB does not change.* ★ XtraDB identifies itself as InnoDB: ✦ ALTER TABLE my_table ENGINE=INNODB; or CREATE TABLE my_table (a INT) ENGINE=INNODB; still works! ★ If you want to revert back, just remove the Percona Packages and install MySQL packages. ✦ Both Debian/Red Hat packages don’t remove the data directory when you remove the programs. 9 * By default. You must explicitly enable features for incompatibility.
  14. 14. Compatibility (cont.) ★ When you connect from your PHP/Python/Perl/C/C++/ Ruby/.NET/<insert other language> application to Percona Server, you do not need to make any special changes. ★ Your application just sees “MySQL” on port 3306. ★ Really, nothing here changes. 10
  15. 15. Today’s Agenda ★ Percona products at 10 000 feet. ★ A closer look at Percona Server with XtraDB. ★ A closer look at XtraBackup. ★ A quick look into the future. ★ Finding more information. 11
  16. 16. Release Model ★ Safe high value changes, made to market fast. ✦ Short release cycle. ✦ Changes are mostly incremental enhancements. ★ Rebases against new MySQL releases. ✦ i.e. Version number should be reads as: Percona-Server-server-51-5.1.52-rel11.6.140.rhel5.x86_64.rpm 12 Major MySQL Version (MySQL 5.1) Minor MySQL Version (MySQL 5.1.52) XtraDB Release Version (Release 11.6)
  17. 17. ★ Historical average of a new release every 2 months: Releases History 13 Release-1 Dec 2008 Release-2 Dec 2008 Release-3 Feb 2009 Release-4 April 2009 Release-5 April 2009 Release-6 July 2009 Release-7 August 2009 Release-8 Oct 2009 Release-9 Jan 2010 Release-9.1 March 2010 Release-10 April 2010 Release-10.1 May 2010 Release-11.0* June 2010 Release-11.1 June 2010 Release-11.2 July 2010 Release-11.3 September 2010 Release-12.0 September 2010 Release-11.4 October 2010 Release-12.1 October 2010 Release-11.5 October 2010 Release-11.6 November 2010 * Recalled Release. The 12.1 branch is now ‘Release Candidate’.
  18. 18. So what changes? ★ Most of the enhancements fall into two categories: ✦ Performance Improvements ✦ Operational / Usability Features 14
  19. 19. Performance Improvements 15 Improved Buffer Pool Scalability Faster Crash Recovery Improved IO Path + adaptive checkpointing Improved Rollback Segment Scalability*Separate purge thread Data dictionary memory consumption controls Increased number of undo slots* Faster page checksums* Support for different page sizes* Insert buffer controls Completely disable the query cache. Remove excess fcntl calls Per session configuration of innodb_flush_log_at_trx_commit Separate location of double write buffer* Strip comments before using query cache Transaction logs larger than 4G supported. * Changes on disk format. Must use mysqldump to revert to regular MySQL releases.
  20. 20. It’s not all raw performance ★ Many people get carried away with performance. ✦ Consistency of timing is also more important than raw throughput. ✦ Without diagnostics, you won’t get what you are entitled to. 16 An earlier benchmark showing Performance of XtraDB 9.x versus regular MySQL releases. Higher is better. Newer benchmarks are available at http://www.percona.com/ software/benchmarks/
  21. 21. Stability of results ★ A lot of engineering work has been done to minimize variance. ★ Sharp drops in MySQL releases are caused by checkpointing activities. 17 Benchmarks is available at http://www.percona.com/software/benchmarks/
  22. 22. Usability Enhancements 18 Show contents of the buffer pool Import / export of innodb_file_per_table tables Import / export of buffer pool contents Transactional Replication Better handling of corrupted tables Store buffer pool in shared memory segment Save index statistics between restarts Advise in processlist when waiting on Query cache mutex. Improved slow query log User / Index / Table statistics Disable automatic statistics regeneration Show data dictionary Deadlock counter Show Temporary Tables Log connection errors Retain query response time distribution. Bug fixes - ahead of time

  28. 28. Save Buffer Pool Contents ★ Export the contents of the buffer pool to a file called ‘ib_lru_dump’ in the data directory: ✦ SELECT * FROM information_schema.XTRADB_ADMIN_COMMAND /*! XTRA_LRU_DUMP*/; ★ Restored ib_lru_dump: ✦ SELECT * FROM information_schema.XTRADB_ADMIN_COMMAND /*! XTRA_LRU_RESTORE*/; 24 Note: Not the actual contents - it takes 8 bytes to remember the address of a 16K page.
  29. 29. To summarize ★ Many MySQL users are not getting the performance they are entitled to. ✦ They lack visibility into internal operations of MySQL. ✦ Giving a 50% improvement through new features sounds nice. What they don’t realize is they’re losing 100% by not being aware. 25

  37. 37. Advanced Features ★ XtraBackup supports some advanced backup options: ✦ Backup to a stream (can be copied straight across the network, or fed through a compression program). ✦ Throttle to only a limited number of IOPS. ✦ Incremental backup.* 33 * Some special restrictions apply. Data Definition must not have changed since last backup.
  38. 38. Advanced Features (cont.) ★ Report on fragmentation of indexes: ★ $ xtrabackup --stats --tables=art.link* -- datadir=/mnt/data/mysql/ ... table: art/link_out104, index: PRIMARY, space id: 12, root page 3 leaf pages: recs=25958413, pages=497839, data=7492026403 bytes, data/pages=91% ... 34 http://www.mysqlperformanceblog.com/2009/09/14/statistics- of-innodb-tables-and-indexes-available-in-xtrabackup/

  40. 40. MySQL 5.5 ★ In Release Candidate now. ★ An awesome release! ✦ A greatly improved focus on performance. ✦ Some additional diagnostic/usability features. ★ Percona Server will rebase against 5.5. ✦ Work has already began porting features. ✦ We will continue to maintain our 5.1 series. 36
  41. 41. Percona Server Plans ★ Our Blueprints are publicly available through LaunchPad: https://blueprints.launchpad.net/percona-server ★ Percona Server with XtraDB R12.1 is now a release candidate. ✦ It will include the ability to store the buffer pool in shared memory and built-in response time distribution stats. ✦ It will also feature HandlerSocket. 37
  42. 42. XtraBackup Plans ★ XtraBackup 1.5 will support parallel backup: ✦ http://www.percona.com/docs/wiki/percona- xtrabackup:xtrabackup:option-and-variable- reference#parallel ★ This is very helpful for RAID controllers and some SSDs, which require multiple threads to exploit their capacity. 38
  43. 43. Support & Maintenance ★ Feature development is customer-driven. ★ Commercial Support and Maintenance for Percona Server, XtraDB and XtraBackup are available. ✦ http://www.percona.com/support/mysql-support- maintenance/ 39
  44. 44. Support & Maintenance (cont.) ★ Seeking sponsorship of parallel replication: http://www.mysqlperformanceblog.com/2010/11/08/ implementing-parallel-replication-in-mysql/ ★ We need to get more customers involved, to share the cost of this large and ambitious project. 40
