yuxiqian opened a new pull request, #3636: URL: https://github.com/apache/flink-cdc/pull/3636
This closes FLINK-36474. For now, it's not possible to merge timestamp-family data (including `Timestamp`, `ZonedTimestamp`, and `LocalZonedTimestamp`) unless some awkward transform and explicit casting. This PR adds the following type coercions: * `TIME`s, `TIMESTAMP`s, `TIMESTAMP_TZ`s, and `TIMESTAMP_LTZ`s with promoted precision For example, `TIMESTAMP(3)` and `TIMESTAMP(6)` will be considered compatible and data with lower precision will be automatically escalated to the higher one. * `TIMESTAMP_TZ`s and `TIMESTAMP_LTZ`s will be converted to `TIMESTAMP` if necessary. I reused some code from `SystemFunctionUtils#castToTimestamp`, so this implicit behavior should be equivalent to writing explicit castings manually. -- This is an automated message from the Apache Git Service.
