------------------------------------
Summary: Avoid branch/merge for small commits
Key: OAK-638
URL: https://issues.apache.org/jira/browse/OAK-638
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Reporter: Marcel Reutegger
Priority: Minor
The branch/merge features on the MicroKernel were initially introduced to stage
changes of large commits. Currently oak-core creates a branch even for small
changes like updating a property. I think this introduces quite some overhead
for scenarios with highly concurrent updates. E.g. think of a twitter like
application or a forum with comments. Well, basically user generated content.
These update tend to be rather small (couple of nodes) but frequent and
concurrent.
Right now oak-core always does:
- MK.branch()
- MK.commit() to branch
- MK.merge()
For small commits, it ideally should do:
- MK.commit() to trunk
