Hi @tzulitai. Yes, we do have a use case where we need to disable Flink
checkpointing because the time interval checkpointing model does not work with
our constraints. We had to trigger Kafka commits by manually taking offset
snapshot and commit after sink flushes (parallel source/sink operators are
chained together), in this case, the partition offset is not incremented until
the thread exits sink operator logic. Now, the only way to make the commit
accurate is to expose which partition the in-flight message belongs to and we
can consciously +1 to the offset at the time of snapshoting.
> Kafka connector needs to expose information about in-flight record in
> AbstractFetcher base class

> Reporter: Zhenzhong Xu
> Assignee: Zhenzhong Xu
> Priority: Minor

> We have a use case where we have our custom Fetcher implementation that
> extends AbstractFetcher base class. We need to periodically get current in
> flight (in processing) records' partition and offset information.
> This can be easily exposed in AbstractFetcher class.
