Transcript of "What's new in MySQL 5.5? FOSDEM 2011"

  1. 1. <Insert Picture Here>Whats new in MySQL 5.5?Lenz GrimmerMySQL Community Relations Specialist
  2. 2. MySQL 5.5 Highlights• InnoDB becomes the default• Improved Performance & Scalability• Improved Availability• Improved Manageability & Usability• Improved Instrumentation & Diagnostics
  3. 3. InnoDB 1.1 as Default Storage Engine• ACID Transactions, Foreign Keys, Crash Recovery• Plugin replaces built-in version• Newly created tables use InnoDB by default• MyISAM and other Storage Engines still available• Many performance/scalability improvements• Better instrumentation & diagnostics
  4. 4. InnoDB Performance improvements• Multiple/Split Buffer Pool Instances• Multiple Rollback Segments• Improved recovery performance• Native async I/O on Linux• Extended Change Buffering (with delete buffering, purge buffering)• Control of overall I/O capacity• Restored group commit
  5. 5. InnoDB Scalability Improvements• Improved Log Sys mutex• Separate Flush List mutex• Improved Purge Scheduling• Improved default thread concurrency• Control of background I/O threads• Control of using the OS memory allocator• Faster locking algorithms
  6. 6. InnoDB Instrumentation/Diagnostics• InnoDB stats in PERFORMANCE_SCHEMA• More extensive SHOW ENGINE INNODB STATUS• New INFORMATION_SCHEMA tables
  7. 7. Improved Availability• Semi-synchronous Replication• Replication Heartbeat• Replication Slave fsync() options• Automatic Relay Log Recovery• Per-master event filtering• Replication Slave Side Type Conversions• Individual Log Flushing• SHOW RELAYLOG EVENTS
  8. 8. Improved Manageability & Usability• PERFORMANCE_SCHEMA• SIGNAL/RESIGNAL• Pluggable authentication framework• More Partitioning Options
  9. 9. Give it a spin!• Download MySQL 5.5 from the usual place: http://dev.mysql.com/downloads/mysql/• Send us feedback and bug reports: http://bugs.mysql.com/• Questions?
