This should be more effective than current approach (MR job). Concerns & notes:

  • map-only may cause some spans of records to be compacted into multiple result records, which is usually (always?) ok. Multiple updates processing results records should be supported already.
  • main concern is about writing into same table from a Mapper which may cause issues
