Event Hub- howto maximize throughput?

Hi All,

We're building a solution where we're pushing events to an event hub for later processing by stream analytics. We've configured the event hub to use 32 partitions to maximize theoretical throughput. Now, the question is if the event publishers need to do something to maximize the throughput. As I understand it we have three choices.

1. Do nothing, i.e. let the service distribute the events evenly over all partitions
2. Distribute the events using one publisher per partitions as suggested here and here
3. Distribute the events using partitionKey as discussed here

I've tried to read the available documentation but to be honest, I'm still confused about the best approach to maximize throughput.

BR, Max
