    Description

      Recycling for data pages is disabled for now. Empty data pages are accumulated in FreeListImpl#emptyDataPagesBucket, and can be reused only as data pages again. What has to be done:

      • Empty data pages should be recycled into reuse bucket
      • We should check reuse bucket first before allocating a new data page
      • MemoryPolicyConfiguration#emptyPagesPoolSize should be removed
