cdc: Improve scheduler
Feature Request
Is your feature request related to a problem? Please describe:
Goals:
- Ensure correctness. No KeySpan should be overlapped.
- Be effective with many regions. One KeySpan for one region may not be suitable.
- Reduce cost of rebalance. Un-subscribe & subscribe regions will be expensive as incremental scan is needed.
- Boundary of KeySpan should try to align with boundary of regions, to reduce useless entry replications.
