Elasticsearch inbound/outbound traffic

Elastic Stack Elasticsearch
1

Hi,

I'm trying to find out the amount of data produced for internal traffic between elasticsearch nodes. Did not find any useful on internet, and i always think that someone have been playing around with this type of questions before.

My setup: helm install from bitnami.
kubernetes 1.23

elastisearch-master-0
elastisearch-master-1
elastisearch-master-2
elasticsearch-data-0
elasticsearch-data-1
elasticsearch-data-2
elasticsearch-coordinating-only-0
elasticsearch-coordinating-only-1
elasticsearch-coordinating-only-2

My analys that i did was to monitor the networkinterface for each vxlan-calio with wireshark.
and the end result was a bit higher then i expected.

during a 24H cycle in an idle system the data produced around 7gb. (no data written to shard etc)

The problem that i'm facing is that i will create a remote cluster with 4g/5g communications between nodes. And the overhead that i'm facing is bit to high to make is worth it.

Elasticsearch requires low latency network with good bandwidth between the nodes of a cluster as well as the nodes reliably being available for resiliency and performance. Deploying over 4G/5G sounds like a very bad idea.

A very bad idea.
