Yonik, This native code uses in any way the docValues?
In the past I was forced to indexed a big portion of my data with docValues enable. OOP problems with large terms dictionaries and GC was my main problem. Other good optimization can be do facet aggregations offsite the heap to minimize the GC, To ensure that facet aggregations has enough ram we need a large heap, in machines with a lot of ram maybe if this aggregation was made offsite this allow us reduce the heap size. -- Yago Riveiro Sent with Sparrow (http://www.sparrowmailapp.com/?sig) On Friday, June 20, 2014 at 2:33 PM, Yonik Seeley wrote: > On Fri, Jun 20, 2014 at 12:36 AM, Andy <angelf...@yahoo.com.invalid > (mailto:angelf...@yahoo.com.invalid)> wrote: > > Congrats!
