for cross-platform compatibility, we can include the TF Schema--normalized into a tensorflow.metadata.v0.Schema--into the metadata map supplied to ExampleWriteSupport's WriteContext.

To be determined:

  • Ensure that tensorflow.metadata.v0.Schema can be reliably mapped to/from a String (since parquet metadata is a stringly typed map)
  • Decide on a key name in the metadata. I would propose just tensorflow.metadata.v0.schema to preserve the versioning/leave the door open to support further Schema versions.
