【TiDB Usage Environment】Production Environment or Test Environment or POC
【TiDB Version】
【Encountered Issue】
Reading the CDC introduction document, it mentions at the beginning: TiCDC is a TiDB incremental data synchronization tool implemented by pulling TiKV change logs.

Does this TiKV change log refer to the raft log in rocks db? Or is there another set of logs recorded at the TiKV level specifically for TiKV changes?

【Reproduction Path】What operations were performed that caused the issue
【Issue Phenomenon and Impact】

【Attachments】

Please provide the version information of each component, such as cdc/tikv, which can be obtained by executing cdc version/tikv-server --version.

Instead of directly reading the log, call the gRPC API. You can refer to this article:
