Hello folks, what is the recommended system specs for each of the services required for a pinot cluster. Is there a formula to calculate this based on the size of the data?

Hello, depending on your data size and workload, you can go anywhere from 4-32 cores, 4-64GB for the serving nodes.

is that per service like controller, server etc? or you mean overall?

That was for pinot-server. For Controller - the parameter is total number of tables and segments across all tables. Typically 4-8 core will do the job. For broker. 4-16 cores, 4GB to 64GB depending on your workload

cool thanks for your help Mayank
