How do I read events in batches, let's say by batch of 50? Azure function implements batch processing but Azure.Messaging.EventHubs Nuget doesn't provide that functionality out of the box.
The answer to this depends on your scenario; if you'd prefer to read from a single partition and to have explicit control, the PartitionReceiver allows reading in batches. [sample]
If you're looking to work with an event processor type that handles load balancing, checkpointing, and resiliency, theEventProcessor<T>offers the extension point for batch-based processing as well as other customization and control. [sample]
