Description

This node groups the performance and health data about the processing queue that is dedicated to the Stateful Message Service.

This specialized queue (STATEFUL_QUEUE) is available in the dispatcher, guider, and rater instances to provide the Stateful Message Service.

The scope of this queue depends on the instance type:

• In a dispatcher instance, it shows the usage of the stateful service client.
• In the guider and rater instances, it shows the internal usage of the stateful service. The internal usage includes, for example, the stateful service client, the refilling web service.

This queue uses a partition/contract algorithm based thread pool. A subscriber account (in cached customer master data) is handled by one and only one execution thread of the pool, at one moment of time.
