substrait-go

Experimental Go bindings for substrait

Note:

This is work in progress still, things still to do:

Expression parsing
Reading in extension yamls
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
- Rel
  - ReadRel
  - FilterRel
  - FetchRel
  - AggregateRel
  - SortRel
  - JoinRel
  - ProjectRel
  - SetRel
  - ExtensionSingleRel
  - ExtensionMultiRel
  - ExtensionLeafRel
  - CrossRel
  - HashJoinRel
  - MergeJoinRel
- DdlRel
- WriteRel
- ExchangeRel
Plan Building helpers
- ReadRel
  - NamedScanReadRel
  - VirtualTableReadRel
  - ExtensionTableReadRel
  - LocalFileReadRel
- FilterRel
- FetchRel
- AggregateRel
- SortRel
- JoinRel
- ProjectRel
- SetRel
- CrossRel
- HashJoinRel
- MergeJoinRel
- DdlRel
- WriteRel
- ExchangeRel

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.
