Can we have master and ingest nodes set true on same nodes


I have 5 nodes cluster, where i kept 3 nodes , which serve as master and ingest nodes and rest 2 nodes act as only data nodes.

Is this good practise? How the flow will be ? and do we need one more node coordinating node where all three options (M,I and D) will be false.


Not really. If you have dedicated master then that is all they should do, no indexing, no ingesting.

I don't know your use case, but for such a small cluster you are probably better off making all nodes master+data+ingest.

we have huge data and cluster size is increasing we are planning to move it to 10 node cluster .so is it good to keep 3 master node and 1 ingest node and rest as data nodes.Let me know your opinion


Yes, that would be a sane idea.

Any suggestion on coordinating node.Should it be there ? and if yes then how many nodes ?


If you want one, start with just that one and see how it performs.

so how ingest node and coordinating node differ in flow..I am little confused in both.Let suppose, if we have 3 node master, 1 ingest node, 1 coordinating node and 5 data node ccluster


Ingest node -
Coordinating node -

Ingest is for processing of data into the cluster.
Coordinating is for querying of that data, kind of like a load balancer.
