-----------------------------------
Summary: IndexingConfigurationImpl.getAggregateRules() should
return null in case no aggregate rules are configured
Key: JCR-3556
URL: https://issues.apache.org/jira/browse/JCR-3556
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: indexing, jackrabbit-core
Affects Versions: 2.6, 2.5.3, 2.4.3, 2.2.13
Reporter: Sergiy Shyrkov
Priority: Minor
Right now the IndexingConfigurationImpl.getAggregateRules() returns an empty
array in case no rules are configured as this it is initialized in the init()
method as follows:
aggregateRules = idxAggregates.toArray(new AggregateRule[idxAggregates.size()]);
so it is never null, but rather an empty array.
This causes small overhead when updating index in case no aggregate rules are
configured (in our case on the version store).
The
org.apache.jackrabbit.core.query.lucene.SearchIndex.retrieveAggregateRoot(Set<NodeId>,
Map<NodeId, NodeState>) method opens the reader and searches for terms
(_:AGGR_NODE_UUID) in any case.
Could we change the IndexingConfigurationImpl.init() to set aggregateRules to
null when no aggregate rules are configured?
