 # Summary
 
-Support `BatchSplit` feature that split one Region into multiple Regions at a time if the size is large enough. This includes modifications of both TiKV and PD. For TiKV, every round of split-check produces not only one split key but multiple split keys and change inner split related interface into batch style. For PD, add RPC `AskBatchSplit` and `ReportBatchSplit` to permit TiKV asking for `region_id` and `peer_id` in batch.

-Add `AskBatchSplit` to replace `AskSplit` , it is called when TiKV produces some split keys for one Region and asks PD to allocate new `region_id` and `peer_id` for that Region. `split_count` in `AskBatchSplitRequest` indicates the number of Region to be generated, and `AskBatchSplitResponse` returns all new allocated ids to TiKV.
