pg-amqp-bridge vs RSMQ: What are the differences?
pg-amqp-bridge: Send Messages from PostgreSQL to RabbitMQ. This tool enables a decoupled architecture, think sending emails when a user signs up. Instead of having explicit code in your signup function that does the work (and slows down your response), you just have to worry about inserting the row into the database; RSMQ: A lightweight message queue for Node.js that requires no dedicated queue server. Just a Redis server. tl;dr: If you run a Redis server and currently use Amazon SQS or a similar message queue you might as well use this fast little replacement. Using a shared Redis server multiple Node.js processes can send / receive messages.
pg-amqp-bridge and RSMQ can be categorized as "Message Queue" tools.
pg-amqp-bridge and RSMQ are both open source tools. RSMQ with 1.07K GitHub stars and 78 forks on GitHub appears to be more popular than pg-amqp-bridge with 251 GitHub stars and 14 GitHub forks.
