We are experience unpredictable latencies for writing into an Event Hub. In general the synchronous write to Event Hub returns in under 100ms. But in 1-2% of the writes we see up to 10.000ms latency. I dont't think it's a client problem, because I run multiple producers on different machines and all experience the same delays at the same time.
Producers use the Java SDK 0.9.0; Event Hub has 10 partitions; 1.1 Million Events are inserted into Event Hub over 30 Minutes; There are 2 Producers (2 VM in the same Azure Region as the Event Hub) each has 50 Threads to insert events.
Any idea if this is the normal behavior of Event Hub - or can we do something to prevent theses long delays?
Kind regards, André
