    Description

      Currently, we only remove data blocks for deleted columns when we run a compaction. If a table is already fully compacted, this won't happen at all. In most cases, it will happen very slowly.

      We should add some kind of in-the-background operation which removes the CFiles corresponding to deleted columns, and modify the delta compaction code paths to actually drop delta data for deleted columns.
