Disque vs pg-amqp-bridge: What are the differences?
What is Disque? In-memory, distributed job queue. Disque is an ongoing experiment to build a distributed, in-memory, message broker. Its goal is to capture the essence of the "Redis as a jobs queue" use case, which is usually implemented using blocking list operations, and move it into an ad-hoc, self-contained, scalable, and fault tolerant design, with simple to understand properties and guarantees, but still resembling Redis in terms of simplicity, performance, and implementation as a C non-blocking networked server.
What is 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.
Disque and pg-amqp-bridge can be primarily classified as "Message Queue" tools.
Disque and pg-amqp-bridge are both open source tools. Disque with 7.37K GitHub stars and 516 forks on GitHub appears to be more popular than pg-amqp-bridge with 251 GitHub stars and 14 GitHub forks.
