Class PeriodicGroupIndexer

java.lang.Object

com.google.gerrit.server.group.PeriodicGroupIndexer

All Implemented Interfaces:

Runnable

public class PeriodicGroupIndexer
extends Object
implements Runnable

Runnable to schedule periodic group reindexing.

Periodic group indexing is intended to run only on slaves. Replication to slaves happens on Git level so that Gerrit is not aware of incoming replication events. But slaves need an updated group index to resolve memberships of users for ACL validation. To keep the group index in slaves up-to-date this class periodically scans the group refs in the All-Users repository to reindex groups if they are stale. The ref states of the group refs are cached so that on each run deleted groups can be detected and reindexed. This means callers of slaves may observe outdated group information until the next indexing happens. The interval on which group indexing is done is configurable by setting index.scheduledIndexer.interval in gerrit.config. By default group indexing is done every 5 minutes.
