Recently I'm working in a project which requires figuring out elastic-search capacity as we will increase a lot msgs in es system per second.

We have 3 types of nodes in es cluster: master, data, client.

how do we know the maximum insert count per second our client can handle? do we need to care about the bandwidth of the client nodes?

as per the above comments, you need to benchmark your cluster hardware and settings with your proposed data structure using a tool like https://esrally.readthedocs.io/en/stable/
