Refactor LARQ so that it becomes easy to plug in different indexes such as Solr
or ElasticSearch instead of Lucene
------------------------------------------------------------------------------------------------------------------
Key: JENA-17
URL: https://issues.apache.org/jira/browse/JENA-17
Project: Jena
Issue Type: New Feature
Components: LARQ
Reporter: Paolo Castagna
Priority: Minor
LARQ currently uses Lucene, we could do the same with/for Solr
(http://lucene.apache.org/solr/) or ElasticSearch
(http://www.elasticsearch.com/).
Examples, as proof of concept, are here:
- https://github.com/castagna/SARQ
- https://github.com/castagna/EARQ
In particular, have a look at IndexBuilder and IndexSearcher interfaces:
-
https://github.com/castagna/EARQ/blob/master/src/main/java/org/openjena/earq/IndexBuilder.java
-
https://github.com/castagna/EARQ/blob/master/src/main/java/org/openjena/earq/IndexSearcher.java
And implementations for Lucene, Solr and ElasticSearch in the corresponding
packages:
-
https://github.com/castagna/EARQ/tree/master/src/main/java/org/openjena/earq/builders
-
https://github.com/castagna/EARQ/tree/master/src/main/java/org/openjena/earq/searchers
If we do this, plugging in a different index becomes very easy.
