-
Guaranteed FIFO, with push-style API, up to 80GB maximum size, 10,000
queues per namespace, 2,000 messages per second, 256KB per message.
 Express
Decreases latency by storing the messages in memory
 Partitions
Managed scale out (at max 16x)
A higher level abstraction from queues, enables pub/sub models with similar
scale out capabilities and consistent pricing
 Filters
Allows subscribers to selectively receive messages
 Rules
Aid in filtering and authorization
 Volatile Subscribers
Can delete on idle, allowing for transient consumers

Event Hub Publisher concept
 Every Event Hub has pre-defined number of
partitions
 Every event has a partition key => mapped to one
of the partitions
Event 1
PartitionKey=A
Event 1
PartitionKey=B
Partition 1
Partition 2
Partition “n”

Direct Receiver
 Receiver connects to a partition and pull messages
 Limited(5) receivers for each partition
Worker 1
Event 1
Pkey = A
Event 2
Pkey = B

 Register a class that implements an EventProcessor
interface
 Client SDK will manage balancing receivers across workers

Pub-Sub with Event Hub
 Consumer groups allow multiple, parallel sets of
subscribers to receive the same events
