Why need "withoutOptions" here? Any risk of breaking changes?

[Amar3tto]

withoutOptions removes the primaryKeyColumns schema option because the Python SDK cannot decode it across the Java/Python expansion boundary. It does not change the output fields or row values, and the regular Java DebeziumIO schema remains unchanged. The only difference is that this metadata is not exposed through the SchemaTransform.

[Abacn]

Shall we treat zero the same as null?

[Amar3tto]

I would keep null as “no limit”, and reject zero
