We have managed to setup xDb in our production environment. Currently, we only setup a single instance of Processing/Aggregation server. We are planning to add another server as a processing/aggregation server to share the load on processing analytics data. I would like to know how to achieve this goal and understand how the servers will handle the job given that both servers are up and running in parallel. Can you please advice the steps or references?
I have read some articles that this can be done but there is not concrete details on how to setup correctly.
Thanks in advance.
