-------------------------------------
Summary: Prefetch external changes
Key: OAK-4724
URL: https://issues.apache.org/jira/browse/OAK-4724
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core, documentmk
Reporter: Marcel Reutegger
Assignee: Marcel Reutegger
Fix For: 1.6
In a cluster with listeners that are registered to receive external changes,
pulling in external changes can become a bottleneck. While processing those
external changes, further local changes are put into the observation queue
leading to a system where the queue eventually fills up.
Instead of processing external changes one after another, the implementation
could prefetch them as they come in and if needed pull them in parallel.
