Azure Service Bus Session Count Scaler

[christopherlombardiconfluence]

Expose scaling on an Azure Service Bus Topic's Subscription's active Session Count, similar to message count except for unique session identifiers.

Azure Service Bus exposes a GetMessageSessions() API call that can retrieve all message sessions that are active.

Use-Case

We have a need to scale based on a number of currently active sessions on an Azure Service Bus Topic or Queue. Sessions are a set of dynamically allocated queues that can be processed across many receiving machines with configuration for Azure Service Bus to define the amount of concurrent sessions and concurrent messages within a session, we plan to utilize sessions to perform work on our distributed system assigning a number of sessions to each machine. Once the number of sessions exceeds our limit of machines * number of sessions, we would like to scale to accommodate greater concurrent processing power.

Specification

• Keda can read a SessionCount variable when supplied an Azure Service Bus Topic + Subscription to scale based off of exceeding.
