DoctorKafka vs RSMQ: What are the differences?
Developers describe DoctorKafka as "A service for Kafka cluster auto healing and workload balancing". DoctorKafka can automatically detect broker failure and reassign the workload on the failed nodes to other nodes. DoctorKafka can also perform load balancing based on topic partitions's network usage, and makes sure that broker network usage does not exceed the defined settings. On the other hand, RSMQ is detailed as "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.
DoctorKafka and RSMQ can be categorized as "Message Queue" tools.
DoctorKafka and RSMQ are both open source tools. It seems that RSMQ with 1.07K GitHub stars and 78 forks on GitHub has more adoption than DoctorKafka with 488 GitHub stars and 68 GitHub forks.
