### Create Client ### Create Client
Information about a TiKV cluster can be found by the address of PD server. After starting a TiKV cluster successfully, we can use PD's address list to create a client to interact with it.

### Batch Operations ### Batch Operations
`RawKV` also supports batch operations using batch. Note that since `RawKV` is not transaction guaranteed, we do not guarantee that all writes will succeed or fail at the same time when these keys are distributed across multiple regions. `RawKV` also supports batch operations using batch.
