> In SFDC connector, there is a class called `ResultIterator` (I will change
> the name to SalesforceRecordIterator).
> It was using by only PK-Chunking currently. It encapsulated fetching a list
> of result files to a record iterator.
> However, the csvReader.nextRecord() may throw out network IO exception. We
> should do retry in this case.
> When a result file is fetched partly and one network IO exception happens, we
> are in a special situation - first half of the file is already fetched to our
> local, but another half of the file is still on datasource.
> We need to
> 1. reopen the file stream
> 2. skip all the records that we already fetched, seek the cursor to the
> record which we haven't fetched yet.
