Replacing Legacy Message Queueing Solutions with RabbitMQ
summary
Argues RabbitMQ can replace DEC Message Queue by implementing a drop‑in PAMs API that preserves function names, arguments and return codes; builds a name server (RPC) to map numeric group/queue IDs to names, uses direct/fanout exchanges for routing and RabbitMQ streams for journaling, implements consume semantics with background threads and per‑queue channels, and runs on OpenVMS x86 with ports underway for Windows/Linux. Omits content‑based consumes and some obscure legacy features but proves workable for hundreds of legacy apps.
