If you find yourself performing SELECT queries on the messages, and
their order is less important then consider using a relational database
instead.

If not all messages are routed in an identical way, or you find yourself
writing lots of database trigger code then I would suggest using a
message broker. RabbitMQ can cope with long persistent queues, with
messages of variable sizes.

If performance is a consideration then you should run some benchmarks
for your expected workload.
