Using Lucene in a multi-server environment

[bradw]

Hi,

One of my concerns regarding using Alfresco is how to reconcile the Lucene indexes of multiple servers.  Lets say that my Alfresco implementation uses 3 app servers, each of which separately runs Lucene.  Not being a Lucene wizard, I'm not sure how best to replicate the index updates to all servers, so that search results are consistent.  Should a DB store be used for the index instead of a separate file store for each server, or perhaps a shared filesystem store for the index?

Have you experimented with this at all?

Thanks,
Brad

Hi,

We include functionality in the enterprise offering to ensure your lucene indexes are kept in synch in a clustered environment.

You can request a trial of the enterprise version so you could try it out…

Perfect. As it happens, I am currently using the enterprise eval version.  Where do I start looking?

Thanks,
Brad

will this functionality (clustered lucene index) be available in the GA release of the WCM?

See index-tracking-context.xml.sample, which is one of the config extension samples that gets shipped with the tomcat or jboss bundles.  It is in the 1.4.
