loserwang1024 opened a new pull request, #3233:
URL: https://github.com/apache/flink-cdc/pull/3233
Current , when sink is not instanceof TwoPhaseCommittingSink, use
input.transform rather than stream. It means that pre-write topology will be
ignored.
```
private void sinkTo(
DataStream<Event> input,
Sink<Event> sink,
String sinkName,
OperatorID schemaOperatorID) {
DataStream<Event> stream = input;
// Pre write topology
if (sink instanceof WithPreWriteTopology) {
stream = ((WithPreWriteTopology<Event>)
sink).addPreWriteTopology(stream);
}
if (sink instanceof TwoPhaseCommittingSink) {
addCommittingTopology(sink, stream, sinkName, schemaOperatorID);
} else {
input.transform(
SINK_WRITER_PREFIX + sinkName,
CommittableMessageTypeInfo.noOutput(),
new DataSinkWriterOperatorFactory<>(sink, schemaOperatorID));
}
}
```
（ps: the modify of StarRocksUtils just apply spotless)
