Does DDM Support Distributed JOINs?

Yes. DDM supports distributed JOINs.

  • Redundant fields are added during table design.
  • Cross-shard JOIN is implemented by using broadcast tables, ER shards, and ShareJoin.
  • Currently, DDM does not allow cross-schema update or deletion of multiple tables.
