Re: Data Node Allocation Weight

[Mark Walkom]

If you have hot and cold data, you could allocate the cold data to those
nodes (see
http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-cluster.html
).

Or you could allocate those nodes to be master only, but that may be a
resource waste.

Data Node Allocation Weight

[smonasco]

Hi,

I'm in a bit of a crunch.  We have some servers we added to our cluster 
whose processors were not as good as the older servers.  I'd rather not get 
into how we got swindled into accepting them, but this leaves me in a place 
with imbalanced hardware between my nodes.

The crunch bit comes in that during our peak load we begin to have slow 
queries which lead to rejected queries once we max out the CPUs on the new 
machines.

I'm trying to find a way to tell ES to put more shards on the more powerful 
nodes.

The simplest idea, would be if I could give a weight to servers or 
something else rather than try to move shards around by hand, create zones 
and force some indexes into them, etc.
