Review comment:
What's the motivation from line 180 - 183? If you want to copy, we can
simply do `State state = new State(sourceState)`

> In SFDC(salesforce) connector, we have partitioning mechanisms to split a
> giant query to multiple sub queries. There are 3 mechanisms:
> * simple partition (equally split by time)
> * dynamic pre-partition (generate histogram and split by row numbers)
> * user specified partition (set up time range in job file)
> However there are tables like Task and Contract are failing time to time to
> fetch full data.
> We may want to utilize PK-chunking to partition the query.
