This can be a batch of one for low-throughput scenarios, however, for high volume use cases, it's recommended that you batch several events together per publish to achieve higher efficiency.

 ### Partner namespace
 A partner namespace is a regional resource that has an endpoint to publish events to Azure Event Grid. Partner namespaces contain either channels or event channels (legacy resource). You must create partner namespaces in regions where customers request partner topics or destinations because channels and their corresponding partner resources must reside in the same region. You can't have a channel in a given region with its related partner topic, for example, located in a different region.
