Leonard Xu updated FLINK-36041:
-------------------------------
Affects Version/s: cdc-3.1.1
> Eliminate Calcite dependency during runtime
> -------------------------------------------
>
> Key: FLINK-36041
> URL: https://issues.apache.org/jira/browse/FLINK-36041
> Project: Flink
> Issue Type: Improvement
> Components: Flink CDC
> Affects Versions: cdc-3.1.1
> Reporter: yux
> Assignee: yux
> Priority: Major
>
> Currently, runtime operator `PreTransformOp` and `PostTransformOp` heavily
> relies on Calcite to parse expression rules. Calcite is a heavy dependency
> and quite easily to cause conflicts (since it's a Flink dependency, too).
> It would be better if we could construct those abstract grammar data
> structures early (in composer, before submitting jobs). It could improve
> runtime execution performance and provide better error messages given
> malformed expressions.
