Michael Dürig commented on OAK-659:
-----------------------------------
At revision 1513469 I committed an initial fix, which,
* still keeps transient changes from commit hooks in memory when running with a
MicroKernel. See TODOs in {{KernelNodeState.builder()}},
* when running on SegmentMK the relevant implementations in
{{SegmentNodeStore}} falls back to their defaults, which might not be optimal.
[~jukkaz] could you have a look at the respective TODOs in {{SegmentNodeStore}}
when you come around to it?
> Move purge logic for transient changes below the NodeBuilder interface

>
> Currently transient changes are purged down to a persisted branch once a
> certain size threshold is hit. This logic currently resides in {{RootImpl}}.
> However this approach doesn't catch the case where a lot of content is added
> by a commit hook (e.g. index updates) since commit hooks operate on the
> {{NodeBuilder}} level which is below {{Root}}.
> The aim of this issue is to pursue ways to push the purge logic further down
> below the {{NodeBuilder}} interface.
