Grant Ingersoll commented on SOLR-1277:
---------------------------------------
{quote}Yeah, I wonder myself if thats true anymore. Indexing is not the object
spewing process it used to be with all the reuse that goes on now - and it can
operate in much less RAM with more constant garbage created to collect. When I
was profiling a while back looking for a possible indexing leak, I didn't see
much for pausing. A search node can have very large caches tied to readers that
all drop at once on commit, and can require a much larger heap to accommodate
these caches. I think thats a more common scenario that creates these longer
pauses.

Yep, this is consistent with what I've seen in a good chunk of either: really
high end systems (people really pushing the limits of not only Solr, but their
hardware, etc) or really poorly configured systems.

> The goal is to give Solr server clusters self-healing attributes
> where if a server fails, indexing and searching don't stop and
> all of the partitions remain searchable. For configuration, the
> ability to centrally deploy a new configuration without servers
> going offline.
> We can start with basic failover and start from there?
> Features:
> * Automatic failover (i.e. when a server fails, clients stop
> trying to index to or search it)
> * Centralized configuration management (i.e. new solrconfig.xml
> or schema.xml propagates to a live Solr cluster)
> * Optionally allow shards of a partition to be moved to another
> server (i.e. if a server gets hot, move the hot segments out to
> cooler servers). Ideally we'd have a way to detect hot segments
> and move them seamlessly. With NRT this becomes somewhat more
> difficult but not impossible?
