Csaba Varga commented on SLING-12266:
-------------------------------------
I would be interested in writing code for this, if it seems worthwhile. I think
it could speed things up nicely, but I may be missing some potential issue here.
> Cache initial repository state to improve JCR_OAK performance

> Key: SLING-12266
> URL: https://issues.apache.org/jira/browse/SLING-12266
> Project: Sling
> Issue Type: Improvement
> Components: Testing
> Affects Versions: Testing Sling Mock 3.4.18
> Reporter: Csaba Varga
> Priority: Minor
>
> A lot of effort goes into preparing an Oak Mock repository from scratch: node
> types need to be registered, indexes need to be created, and all this happens
> over several commits. None of this work depends on the test case itself, so
> it will always result in the exact same repository state. We could take the
> root NodeState from the first repository we build, then build subsequent
> repositories on top of it, avoiding most of the redundant work. Commits can
> be relatively expensive even in memory, so each one we avoid can save a lot
> of time in the long term.
>
> This would require extending the contract between Testing Sling Mock and the
> ResourceResolverTypeAdapters, to add optional "make snapshot" and "build repo
> from snapshot" operations. For adapters that don't support them, we would
> keep rebuilding things from scratch.
