Review Comment:
I see, and I just spotted this in the README that each task will generate
segments for one particular table partition, then it make sense to use a
sequenceId local to each task.
```
The parallelism of the job *must* be set the same as the number of
partitions of the Pinot table(same as upstream), so that the sink in each task
executor can generate the segment of same partitions.
```
