Elasticsearch - Does it matter to which node I send an update? -

-

in elastic cluster muliple nodes, 1 master, matter node document update or delete request hits.

currently find out master node asking 1 of nodes returns complete list of nodes , master node id use transport address for. point update traffic @ transport address.

can requests sent node (as long available) no issues?

the short answer no, doesn't matter. send data node like.

an important thing remember "master" node change on time. let's have 3 node cluster , node master. if node ever goes down maintenance node b or c become master.

another important node: never need know node master. that's wasted query time. send data a, b, or c, same. don't try outsmart es, let product lot of work you.

we have 3 node production cluster behind load balancer , round-robin incoming requests 3 nodes.
