Question - Define BizTalk Server Convoy and correlation sets.
Answer -
The Biztalk server detects the potential for specific race conditions, which ensures that all correlated messages are received by the same orchestration instance. The potentiality of these race conditions is sensed by the BizTalk server.
These messages are treated as a convoy. All such messages which match with the general subscription are evaluated against the convoy set and the matched convoys are routed through an existing port.
