In previous versions, the defragmentation operation was part of the main thread, which was scheduled periodically but blocked other operations in the database; after 5. 5, the thread can be isolated; method: innodb_purge_threads = 1

This should allow fragment collection to be more timely without affecting the operations of other threads.

Improved Purge Scheduling

-The InnoDB purge operation is a type of garbage collection that runs

Periodically. In previous versions, the purge was part of the master thread, meaning that it could

Block other database operations when running. In MySQL 5.5 this operation can run in its own

Thread, allowing for more concurrency. Users can control whether the purge operation is split into its

Own thread with the innodb_purge_threads configuration option, which can be set to 0 (the

Default) or 1 (for a single separate purge thread).
