    Description

      1) Use circular reuse
      2) Schedule to run full compaction every second (but only one compaction runs at a time)
      3) compaction runs fine for a couple of times, but then seeing checksum error afterwards
      4) Note that there is ongoing mutation and new snapshot is creating while compaction is running continuously
