TL;DR
- MySQL 8.0同士でレプリケーションを組んでいると、スレーブから以下のような
MY-010956とMY-010957がぼこぼこエラーログに吐かれることがある
2019-05-20T14:25:17.121864+09:00 5 [Warning] [MY-010956] [Server] Invalid replication timestamps: original commit timestamp is more recent than the immediate commit timestamp. This may be an issue if delayed replication is active. Make sure that servers have their clocks set to the correct time. No further message will be emitted until after timestamps become valid again.
2019-05-20T14:25:17.177804+09:00 5 [Warning] [MY-010957] [Server] The replication timestamps have returned to normal values.
- 実害はほぼないはずだけど、エラーログの肥大化に注意
- もうちょっと出力を穏やかにできないかね? ってFeature Requestを出した …
