Overview
The Ordered Service is required by the Ordered Routing Queue Strategy. A function defined in APL code will extract values from any routed UDR or bytearray to decide which partition queue to add it to.
Ordered Routing allows the system to utilize multicore cpus, but still have deterministic order.
Configuration of the Ordered Service
If there are session updates from a collection point that are encoded to a user defined UDR type Ordered.Subscriber.Update with the field 'id' containing a session id, the following example shows how the values are read and added to the ordered.SessionIdentifier that the queue strategy will use to hash and select a partition based on.
