Abstract: Processing related messages in different queues in a middleware system is provided. The middleware system receives a first message that comprises a body and a header. The header includes a first message ID and a relationship key, wherein the relationship key denotes a relationship between the first message and a correlated second message. The system reads the relationship key from the header of the first message. The middleware system stores the first message in a first queue and stores the first message ID and relationship key in a relationship object in a cache list. A consumer API retrieves the first message from the first queue and extracts the relationship key from the header. The consumer API identifies, according to the relationship key, a second message ID in the relationship object and retrieves the correlated second message from a second queue according to the second message ID.
