> {quote}
> Attached OAK-2829-improved-doc-cache-invaliation.patch which is a suggestion on how to avoid invalidating the entire document cache when doing a {{backgroundRead}} but instead making use of the new journal: ie only invalidate from the document cache what has actually changed.
> I'd like to get an opinion ([~mreutegg], [~chetanm]?) on this first, I have a load test pending locally which found invalidation of the document cache to be the slowest part thus wanted to optimize this first.
> Open still/next:
>  * also invalidate only necessary parts from the docChildrenCache
>  * junits for all of these
