Description
It appears that rebalancing partitions (such as in response to autoscaling) can be very slow, e.g. take more than 10 seconds.
This means that clients can experience bad latency tails in such situations.
It should be possible to significantly improve this by optimizing the partition handoff process.

Research direction
The issue names no files, tests, or entry points. Start by locating the partition rebalancing and handoff implementation, then measure the latency of movements that take more than 10 seconds. Done means the handoff process is substantially faster without losing correct partition ownership or client behavior.
