---------------------------------
Summary: More efficient node traversal during garbage collection
Key: JCR-3490
URL: https://issues.apache.org/jira/browse/JCR-3490
Project: Jackrabbit Content Repository
Issue Type: Improvement
Reporter: Unico Hommes
Assignee: Unico Hommes
Fix For: 2.6
During the 'marking' stage the data store janitor runs over all nodes in the
repository and updates the last modified date of any binary that is stored in
the data store table that it finds. However, this process loads all node states
in the repository individually which means that a separate database select is
run for every node in the repository. This is very inefficient. We can improve
on this manyfold by using the same strategy as is used by the consistency
checker: we load batches of node info objects at once that already contain
enough information to do our processing.
