      Description

      Do performance analysis, and find a good query block size value for the client to send to the server . Need to understand the memory usage also for greater query block size values.

      This issue is related to DERBY-959 and DERBY-1441.

      DERBY-959 has server side changes
      DERBY-1441 issue talks about client side changes

      DERBY-959 talks about 'Allowing use of QRYDTA block sizes greater than 32k'. As part of discussion on that jira, it was suggested that the performance analysis to decide a good query block size value for the client to send to the server be a separate task.

      Here is the link to the discussion that happened for DERBY-959.
