MySQL 的发展轨迹


MySQL Database


• MySQL 5.6 基於 MySQL 5.5 加上以下的改良 :• Optimizer for better Performance, Scalability• Performance Schema for better instrumentation• InnoDB for better transactional throughput • Replication for higher availability, data integrity• “NotOnlySQL” options for more flexibility

MySQL 5.6: A Better MySQL


MySQL 的架构Support for common development languages/platforms

Efficient multi-threaded session handling

Full DML, DDL parsing, cost based optimizer, caching of queries and result sets

Flexible Storage Engine options for application specific storage needs

Flexible logging and physical storage options


• Subquery Optimizations• File sort optimizations with small limit

•4X better execution time – 40s to 10s

• Index Condition Pushdown•160X Better execution time – 15s to 90ms

• Postpone Materialization of views/subqueries in FROM•240X better execution time for EXPLAIN – 8m to 2s

• Batched Key Access and Multi Range Read•280X Better execution time – 2800s to 10s

DBT3 Q13: “Customer Distribution Query”


Better Diagnostics and Debugging • EXPLAIN• INSERT, UPDATE, and DELETE• JSON format for better readability

• Persistent Optimizer Statistics - InnoDB• Optimizer Traces

MySQL 5.6: 优化器


• Statements/Stages• 那些是耗用资源最多的查询 ? 它们的时间都用在那里 ?

• Table/Index I/O, Table Locks• 那些应用的表 / 索引造成最多的负荷况冲突 ?

• Users/Hosts/Accounts• 那些应用的用户 / 主机 / 程序耗用最多的资源 ?

• Network I/O• 网路的负荷如何 ? 连线的怠机状况如何 ?

• Summaries• 依线程，用户，主机，帐户或物件总合的统计

MySQL 5.6: Performance Schema 的用途Improved Database Profiling/Application Tuning – Less Than 5% Overhead


• Better Performance, Scale• Improved thread concurrency, LRU flushing• Reduced contention during file extension• Increase max redo log size• Separate tablespaces for undo log• Fast checksum

• Better Recovery• Dump and restore buffer pool

• Better Usability• Full-text Search• Variable page sizes – 4k, 8k

MySQL 5.6: 复制Largest EVER set of Enhancements


5x Higher Replication Performance

• SysBench, running across 10 x schemas

• Oracle Linux 6.1, Oracle Sun Fire x4150 m2 Server


全域事务代码

• Simple to track & compare replication across the cluster– Unique identifier for each transaction written to the Binlog

• Automatically identify the most up-to-date slave for failover

• Deploy n-tier replication hierarchies
