[jira] [Created] (IGNITE-13720) Defragmentation parallelism implementation

Anton Kalashnikov created IGNITE-13720:
------------------------------------------

             Summary: Defragmentation parallelism implementation
                 Key: IGNITE-13720
                 URL: https://issues.apache.org/jira/browse/IGNITE-13720
             Project: Ignite
          Issue Type: Sub-task
          Components: persistence
            Reporter: Anton Kalashnikov
            Assignee: Anton Kalashnikov


Defragmentation is executed in a single thread right now. It makes sense to execute the defragmentation of partitions of one group in parallel.

Several parameters will be added to the defragmentation configuration:
 * checkpointThreadPoolSize - the size of thread pool which would be used by checkpointer for writing defragmented pages to disk.
 * executionThreadPoolSize - the size of the thread pool which shows how many partitions maximum can be defragmented at the same time.
