This feature allows reading the DeltaCAT catalog (Iceberg, internal catalog etc.) into a Daft distributed dataframe. It also provides hints regarding data layout to Daft reader so that the reads are optimized and no worse than existing compactor.

Expected Features

  • Reading entire table into memory.
  • Leverage Partition Pruning using DeltaCAT metadata.
  • Leverage sort order policy using DeltaCAT metadata.
  • Support merge on read and hence, delete deltas.
  • Unblocks [Iceberg] Daft Dataframe Reader #170.
