Configuring Stanbol to use an external Solr index

[Tarrant Marshall <Ta...@sbs.com.au>]

Hi

Does anyone have any insight on if it's possible to configure Stanbol to use an external Apache Solr core? If so, how?

Scenario is to use a preferred SolrCloud cluster that has replication for high availability and a load balancer end point.

Thanks
Tarrant

Hi Tarrant,

The FST linking engine [1] requires an embedded SolrCore (as it
heavily uses low level Lucene APIs). However note - FST linking is all
in-memory. Only for looking up the labels and types of linked entities
(as required to write fise:TextAnnotation) the FST engine needs to
retrieve documents from the Lucene index. However for that it does use
a cache. So if you set the size to the cache >= the number of
documents in the index this engine operates all in-memory.

The SolrYard (as used by the Entityhub Linking Engine [2]) can be
configured with an external Solr Server. Just configure the HTTP URL
to the Core in the SolrCore field.

* Solr Index/Core (org.apache.stanbol.entityhub.yard.solr.solrUri):
This can be either the URL of a SolrServer, the absolute Path to an
index/core an the local file system or just the core name to use the
EmbeddedSolrServer internally managed by the SolrYard

best
Rupert
