Subject Re: parameters to decide solr memory consumption
Date Wed, 20 Jun 2012 11:36:58 GMT
This is really difficult to answer because there are so many variables;
the number of unique terms, whether you store fields or not (which is
really unrelated to memory consumption during searching), etc, etc,
etc. So even trying the index and just looking at the index directory
won't tell you much about memory consumption.

And memory use has been dramatically improved in the 4.x code line, so
anything we can say is actually wrong.

Not to mention that your particular use of caches (filterCache, queryResultCache
etc) will change during runtime.

I'm afraid you'll just have to try it and see.

Yes, LIA is accurate...
