Amazon MQ vs Sparrow: What are the differences?
Developers describe Amazon MQ as "Managed Message Broker Service for ActiveMQ". Amazon MQ is a managed message broker service for Apache ActiveMQ that makes it easy to set up and operate message brokers in the cloud. On the other hand, Sparrow is detailed as "A really fast lightweight queue written in Ruby that speaks memcache". Sparrow keeps messages in memory, but persists them to disk, using Sqlite, when the queue is shutdown.
Amazon MQ and Sparrow can be categorized as "Message Queue" tools.
