What`s the meaning of the 'retention_minutes'?

Help

I want to know the meaning of pipelines_errors_retention_minutes.

I set the value to 1.

set global pipelines_errors_retention_minutes = 1;

However, after more than a minute, PIPELINES_ERRORS is shown

Can you explain more about what you mean by “PIPELINES_ERRORS is shown?”

The very most recent errors are never deleted, at least until the pipeline is dropped. Perhaps we could add a way to clean this up, as this is a common source of confusion.
