Kestrel is a simple, distributed message queue system written in Scala, originally developed at Twitter and based on Starling. It offers fast, durable, reliable queues with loose ordering across a cluster, but is now deprecated and unmaintained.

Use cases

  • run a simple distributed message queue on the JVM
  • queue messages durably with disk journaling
  • scale message queues horizontally without cluster coordination
  • reliably hand off messages when clients crash
  • replace starling with a more robust message queue

When to choose

  • you need a small, fast, easy-to-deploy queue and can accept loose ordering
  • you want durable queues without heavy clustering machinery
  • you're maintaining a legacy system already built on Kestrel

When to avoid

  • you need strong global ordering or transactions
  • you need an actively maintained project with fixes and support
  • you operate at very large scale with diverse workloads
  • you need modern features like rich routing or streaming semantics
