Kestrel vs pg-amqp-bridge: What are the differences?

Developers describe Kestrel as "Simple, distributed message queue system". Kestrel is based on Blaine Cook's "starling" simple, distributed message queue, with added features and bulletproofing, as well as the scalability offered by actors and the JVM. On the other hand, pg-amqp-bridge is detailed as "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.

Kestrel and pg-amqp-bridge can be categorized as "Message Queue" tools.

Kestrel and pg-amqp-bridge are both open source tools. Kestrel with 2.8K GitHub stars and 326 forks on GitHub appears to be more popular than pg-amqp-bridge with 251 GitHub stars and 14 GitHub forks.
