      Perf. Test Plan

      1. Run data prepopulation
      2. Run steady state load for X seconds as Phase 1.
      3. Make one test case dependent change, e.g. triggering garbagecollect, altering table, etc., and continue the steady state load for Y seconds as Phase 2.
      4. Compare the performance metrics beween Phase 1 and Phase 2.

      The workload used in the test was generated from tlp-stress.

      Steady state load Read : Write : Delete == 5 : 4 : 1, and the QPS was kept at 3K/s.

      Description

      The testing cluster should be pre-populated with ~200GB data in each node. The baseline cluster has the table created with provide_overlapping_tombstones disabled. The other cluster has the table with provide_overlapping_tombstones == row. Compare the read, write and compaction performance between those 2 clusters.
