Oracle plans to invest in MySQL to improve performance and scalability, simplify management, and provide better integration with Oracle products. Key focuses for MySQL include the web, embedded systems, telecom, and the LAMP stack. MySQL 5.5 offers major performance improvements such as the InnoDB storage engine becoming default and multiple buffer pools and rollback segments for increased scalability.

9. MySQL Architecture

10. Storage Engine - MyISAM Highlights Default MySQL engine (v5.1 and earlier) No practical limits on data storage Very efficient storage Easily handles high-speed data loads Has B-tree, R-tree, and Full-text Indexes Supported by special index memory caches Offers compressed data option Supports geospatial operations Uses table level locks Does not do transactions Backup/point-in-time recovery supported Best Use Cases Data warehouse High-traffic web sites MyISAM

11. Storage Engine - InnoDB Highlights Provides ACID transaction support 64TB data storage limit per tablespace Higher storage cost Slower data load speed than most other engines Offers MVCC/Snapshot read Has B-tree and clustered indexes Supported by special data & index memory caches Provides foreign key support Does not offer compressed data option Uses row level locks and has custom isolation levels Has crash recovery Backup/point-in-time recovery supported Best Use Cases OLTP InnoDB

16. © 2010 Oracle Corporation – Proprietary and Confidential Improved Recovery Performance “ Standard SysBench recovery improved from 7 hours to 14 minutes” In many circumstances, recovery time is downtime . Only MySQL Replication can avoid this situation, but it is not always applicable

26. What Facebook is saying I previously tested InnoDB on an 8-core server to determine how many IOPs it can do for a simple IO-bound workload. The limits were ~12k disk reads/second for MySQL 5.0 and ~18k reads/second for MySQL 5.1. I just repeated the tests using a 16-core server and the results are much better. I can get 20,000 to 30,000 disk reads/second using InnoDB 5.1. InnoDB 5.5 appears to be capable of 50,000 to 70,000 disk reads/second courtesy of support for multiple buffer pools (innodb_buffer_pool_instances).
