> Key: FLINK-37429
> URL: https://issues.apache.org/jira/browse/FLINK-37429
> Project: Flink
> Issue Type: Improvement
> Components: Flink CDC
> Affects Versions: cdc-3.3.0
> Reporter: Xiao Huang
> Assignee: Xiao Huang
> Priority: Minor
> Labels: pull-request-available
> Fix For: cdc-3.4.0
>
>
> At present, Flink CDC uses janino to evaluate value for expressions in
> transform operator. However, the generated expression codes use original
> column name as variable name, which cannot support columns whose name does
> not conform the standard for java variable names (e.g. `timestamp-type`).
> This problem can be solved by mapping each column name to a new name when
> generating expression code.
