Can the number and size of TiDB slow logs be configured?
【Resource Configuration】
This seems to only be effective for TiDB’s own logs, not for slow logs.
There are more logs for TiFlash. Do these also need to be cleaned manually?
max-days applies to both tidb.log and slow logs simultaneously.
Try this, it looks like you have configured it, but it doesn’t seem to be working?
Yes, I configured it but it didn’t work. There are still a bunch of tiflash_tikv logs.
This is the configuration for tiflash_learner. I didn’t see any configuration for the number of logs. You can make a suggestion, but the official recommendation is not to modify the content below this.
In earlier versions, it seems that these two parameters could be set.
If you have a test environment, you can verify it. Do not touch the production environment.
