• CI building and testing the implementation
• Serialization/Deserialization of some expression types:
  • IfThen
  • SwitchExpression
  • SingularOrList
  • MultiOrList
  • Cast
  • Nested
  • Subquery
• Serialization/Deserialization of Plan and Relations
  • Plan
  • PlanRel

    • ReadRel
    • FilterRel
    • FetchRel
    • AggregateRel
    • SortRel

    • ExtensionSingleRel
    • ExtensionMultiRel
    • ExtensionLeafRel
    • CrossRel
    • HashJoinRel
    • MergeJoinRel
  • DdlRel
  • WriteRel
  • ExchangeRel
• Plan Building helpers
  • ReadRel
    • NamedScanReadRel
    • VirtualTableReadRel
    • ExtensionTableReadRel
    • LocalFileReadRel
  • FilterRel

As this is built out, you can expect refactors and other changes to the structure of the package for the time being. The API should not yet be considered stable.

Protobuf bindings come from substrait-protobuf.
