      Description

      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.
