As you see, that query runs for 47 seconds at the moment I catch it.


How fast is it when you rerun the query?

I doubt any other queries or updates could slow it down ... unless
cache_invalidation has a lot of entries.
And what fills it?

Anything that access a repository ... and might use a cached version.

I'm asking to understand which table we would need to 'clean up'. If any.

It is just cache_invalidation ... if that is the problem. How many entries does it have?
