    Description

      In order to hit a high water mark for fleshing out ideas in this spike, this ticket is to setup the testing environment that will work around current WT readahead issues.

      Requirements

      • Some combination of bash scripts and/or jstests
      • Runs on one machine (m5.8xlarge)
      • 2 shards
        • each has its own dbpath linked to a dedicated gp3 volume w/250 MB/s throughput
        • donor => uses a mongod with readahead enabled
        • recipient => uses a mongod with readahead disabled

      Testing against a much smaller subset of generated data would be a good idea to validate the testing procedure.
