Why change to int64? Can it be negative?

What problem does this PR solve?
Keyspans to add & keyspans to remove, must be overlapped. So to be correct, I think we must finish remove jobs first, and then dispatch the add jobs.here
Issue Number: to #48
Problem Description:
Keyspans to add & keyspans to remove, must be overlapped. So to be correct, I think we must finish remove jobs first, and then dispatch the add jobs
What is changed and how does it work?
After each acquisition of the current keyspan, compare the current keyspan with the keyspan of the previous period to establish a corresponding relationship newKeySpan -> needRemoveKeySpan. The running and deployment of the newKeySpan task needs to wait for all the needRemoveKeySpan tasks to stop. This check will be done in Processor.
