Hi!

I have read an tutorial of performance tuning of ES and want to ask if this settings are still active for the actual ElasticSearch 2.4 version:

indices.fielddata.cache.size: 40%  
indices.cache.filter.size: 30%  
indices.cache.filter.terms.size: 1024mb

Thanks  
Nik

Why are you changing these?

I want to increase the cache. Should I let the default settings?

Yes, but why are you increasing them? What is the problem you are solving?

I have big aggregations and want to cache them for future queries.
