Subject [jira] [Commented] (SOLR-3613) Namespace Solr's JAVA OPTIONS
Date Wed, 11 Jul 2012 20:05:34 GMT


Mark Miller commented on SOLR-3613:

Personally, I think if you want to embed Solr, go ahead and use embedded Solr - else run it
as it should be run - in it's own process with it's own heap.

net/net, there are so many positives to simplifying - and this does not sound like a big negative
to me?

bq. advice the customers to move it to a dedicated server when things grow big.

If you are going to end up moving Solr to another server anyhow, I see no problem with starting
with it as a separate process on the same server. That seems more consistent and a more straightforward
transition to me.

I think the decision to make a search engine a war was more about ease of picking up http
plumbing at the time more than any desire to behave like a typical low resource webapp. At
least that's what would make sense to me.

> Solr being a web-app, should play nicely in a setting where users deploy it on a shared
> To this regard Solr's JAVA_OPTS should be properly name spaced, both to avoid name clashes
and for clarity when reading your appserver startup script. We currently do that with most:
{{solr.solr.home,, solr.abortOnConfigurationError, solr.directoryFactory, solr.clustering.enabled,
solr.velocity.enabled etc}}, but for some opts we fail to do so.
> Before release of 4.0 we should make sure to clean this up.
