-------------------------------
Summary: Improve index hot backup
Key: JCR-5142
URL: https://issues.apache.org/jira/browse/JCR-5142
Project: Jackrabbit Content Repository
Issue Type: Improvement
Components: clustering, indexing
Affects Versions: 2.23.1
Reporter: Tom Duffey
As a user with high performance and resiliency needs Jackrabbit should provide
a way to do a hot backup of the Lucene index to avoid having to take a node
offline.
As a step in that direction ClusterNode should provide a way to pause and
resume synchronization. This way we can pause updates on a node, backup the
index and then resume.
Note this ticket only proposes handling the JCR cluster sync operation but the
node itself could also be updating its index. Perhaps a second ticket could be
made to also pause merging the volatile indexes back to the persistent indexes?
