AlfrescoUpdateHandler2 (Alfresco Solr 5.0.a API)

java.lang.Object
- org.apache.solr.update.UpdateHandler
- - org.apache.solr.update.DirectUpdateHandler2
  - - org.alfresco.solr.AlfrescoUpdateHandler2

All Implemented Interfaces:

org.apache.solr.core.SolrInfoMBean
```
public class AlfrescoUpdateHandler2
extends org.apache.solr.update.DirectUpdateHandler2
```
DirectUpdateHandler2 implements an UpdateHandler where documents are added directly to the main Lucene index as opposed to adding to a separate smaller index. For this reason, not all combinations to/from pending and committed are supported. This version supports efficient removal of duplicates on a commit. It works by maintaining a related count for every document being added or deleted. At commit time, for every id with a count, all but the last "count" docs with that id are deleted.
Supported add command parameters:

allowDups overwritePending overwriteCommitted efficiency

false false true fast

true or false true true fast

true false false fastest

Supported delete commands:

command fromPending fromCommitted efficiency

delete true true fast

deleteByQuery true true very slow*

deleteByQuery causes a commit to happen (close current index writer, open new index reader) before it can be processed. If deleteByQuery functionality is needed, it's best if they can be batched and executed together so they may share the same index reader.

Since:

solr 0.9
