hi there, i wonder what is the hardware recommendation for the dedicated client node? i know master is a very light weight node that doesn't require good hardware, but how about client? it's saying the client node is doing the actual gather processing, so i assume it might require more memory like data node. am i right? any recommendation would be greatly appreciated. thanks, TT -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

I don't use client nodes so I can't speak from experience here. Most of the gathering steps I can think of amount to merging sorted lists which isn't particularly intense. I think aggregations (another thing I don't use) can be more intense at the client node but I'm not sure. My recommendation is to start by sending requests directly to the data nodes and only start to investigate client nodes if you have trouble with that and diagnose that trouble as being something that'd move to a client node if you had them. Its a nice thing to have in your back pocket but it just hasn't come up for me.

I have dedicated client nodes for some really intense queries and aggregations. Clients typically have 2GB of heap. Our experience is that 2GB of Heap is sufficient, the client node doesn't do a whole lot. The bulk of the work is done on the data nodes. cheers mike On Monday, November 10, 2014 11:24:41 AM UTC-5, Nikolas Everett wrote: > I don't use client nodes so I can't speak from experience here.
