Elasticsearch deployment advise

Hello,

I'm in need to plan a new deployment of elasticsearch. Single node, 128GB
ram, for log indexing (amount 50 million records a day)

  1. What's the best heap size for elasticsearch 1.4 (running Oracle java
    7u72) ?
  2. Is there some kind of query throttling technique to stop deep drill
    downs to prevent ES out of memory errors ?

Thanks in advance.

20-30Gb per index a day. I've read in setup guide that heap more than 32Gb is useless, that's why I'm asking.

We have 128gb on some nodes and run 30gb heaps. Lucene memory maps files so
the extra memory would be put to good use. The 32gb memory limit comes from
the JVM compressing pointers. It can't compress after 32 and so you see
everything expand in size.
