Public Property ControlQueueBufferThreshold As Integer

Property Value

Int32

A non-negative integer between 0 and 1000. The default value is 256.

Remarks

Increasing this value can improve orchestration throughput by pre-fetching more orchestration messages from control queues. The downside is that it increases the possibility of duplicate function executions if partition leases move between app instances. This most often occurs when the number of app instances changes.
