    Description

      queryable_mmapv1 expects there to be a 1 -> many mapping from pages to blocks. However the pagesize is currently chosen to be 2MB, while some blocks in the backup system (particularly blocks now in S3) are 16MB. The pagesize should be chosen more carefully with respect to the block size.
