Thomas Mueller commented on OAK-9780:
-------------------------------------
More findings:
* Entries could _just_ be in the node state cache (not in the document cache).
I changed the code accordingly.
* The persistent cache has a surprising effect on performance: often node
states are read from there (reading from local disk).
* So I changed the API to also pass the root node state.
* Initial testing shows a speedup of around factor of 2, for local MongoDB. But
those tests are likely not reflecting reality at all (different cache sizes,
remote MongoDB).

> Issue Type: Task
> Components: documentmk
> Reporter: Stefan Egli
> Assignee: Stefan Egli
> Priority: Major

> Proof of concept of cache warming for DocumentNodeStore. Goal is for indexing
> to warm up the cache for a select few eg paths to allow for faster
> iterating/reading of the same eg paths later on
