The ElasticIndexer listens to the repository generated JMS events to perform elastic indexing for ElasticSearch. It implements the org.fcrepo.indexer.Indexer interface for the indexing functionality, which consists of the methods to handle new/updated records and deleted records.
Currently, the ElasticIndexer is experimental, or intended for demonstration purpose only. To use the ElasticIndexer, please download and install ElasticSearch.
Configuration
The indexer is configured using Spring that can be done with the Java bean setter methods. Here is the configuration file showing how to configure and test with the ElasticIndexer:
<!-- Elasticsearch gear -->
<bean id="elasticClient" class="org.fcrepo.indexer.elastic.ElasticClientFactory" factory-method="client"/>
<!-- ElasticIndexer -->
<bean id="elasticIndexer" class="org.fcrepo.indexer.elastic.ElasticIndexer"
p:indexName="testindex" p:searchIndexType="testType"/>
The ElasticSearch client configured above can be initiated with the configuration file elasticsearch.yml:
discovery.zen.ping.multicast.enabled: false
cluster:
name: testCluster
node:
name: testNode
local: true
index:
store:
type: memory
