> Currently, streaming source will be checkpoint in any time, this means UPDATE_BEFORE and UPDATE_AFTER can be split into two checkpoint.
> Downstream can see intermediate state. This is weird in some cases.
> So in this ticket, add streaming-read-atomic:
> The option to enable return per iterator instead of per record in streaming read. This can ensure that there will be no checkpoint segmentation in iterator consumption.
