    Description

      Currently, index builds are restarted from the beginning. To be able to resume an index build, we require the temporary tables used by the hybrid index build to be preserved on startup and the progress information in the internal index build table (one table per index build).

      This ticket implements the resumable index build logic for index builds that were shut down during the side table catch up phase. The internal ident for the index build should have the following phase:

      { _id: <build uuid>,
        phase: "drain writes",
        ...
      }
