substrait-protobuf 0.81.0

Generated Substrait Protocol Buffer Code

substrait-protobuf

Generated Python protobuf bindings for the Substrait specification.

The protobuf definitions from which the code is generated can be found here.

Versions of this package correspond to Substrait releases. vx.y.z of substrait-protobuf will contain code generated from vx.y.z of the substrait repository.

Package Usage

The generated code is available under the substrait module:

import substrait.algebra_pb2
import substrait.plan_pb2
import substrait.type_pb2

Generation and Publishing

Code generation and publishing is handled in the substrait-packaging repository.

When a new version of the Substrait specification is released, automation generates protobuf bindings for that version and pushes them to GitHub with a tag formatted like python/substrait-protobuf/vx.y.z. The automation then publishes that code to PyPI.

Local Generation

The generate_protobuf.sh script can be executed locally to check the protobuf generation.

Set SUBSTRAIT_HOME to a directory containing the Substrait specification.
