      The background compaction server may disrupt the system by generating I/O from compacting the tables. It is worth investigating the impacts when the tables are large, actively accessed and compaction is executed in parallel.

      Tasks:

      • Create a test (the cppsuite could be helpful) that generates large tables that are continuously modified. The test could stress checkpoints as well.
      • Enable background compaction and assess the performance impacts
      • Enable foreground compaction to stress parallel compaction and test WT-11432

      Definition of done:

      • Relevant statistics are measured (throughput, latencies, ...) and compared when the background compaction is enabled/disabled.
