In the last note of the official documentation 主从集群一致性读和数据校验 | PingCAP 文档中心,
- When using the Syncpoint feature for data verification, you need to adjust the GC time of TiKV to ensure that the historical data corresponding to the snapshot is not garbage collected during verification. It is recommended to adjust it to 1 hour and restore the GC settings after verification.
Does this refer to the upstream or downstream? I understand it as downstream. Please confirm, thank you.
