on OAK-2829 re optimizing docCache invalidation using the newly introduced
external diff journal:
{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
