      The background compaction server works as shown below:

      • Find the next table to compact.
        • This can be done using a cursor on the metadata file and processing the files in order
      • If compaction should be executed on the selected table, compact it.
        • For now, this means calling the session API compact on the selected table. This will be improved with WT-11343.
      • Go back to the first step.

      Tasks:

      • Create the internal thread behind the background compaction server
      • Implement the background compaction algorithm
      • Add the relevant statistics

      Definition of done:

      • The background compaction server tries to compact the database files continuously when enabled
      • The background compaction server starts/stops as soon as it is requested by the application
      • The relevant statistics and logs are generated
