hi team

What minimum bandwidth is necessary between indexers and the rest of the platform elements (Heavy Forwarders, Search Heads, Master Cluster, License, Deployment Servers, etc.) for different communications?

@evinasco08

It truly depends on many factors, like number of events, number of forwarders, as well as stakeholder expectations/requirements, and how much time and money you have!
