DistributedLog vs Kestrel: What are the differences?
DistributedLog: High-performance replicated log service, by Twitter. DistributedLog (DL) is a high-performance, replicated log service, offering durability, replication and strong consistency as essentials for building reliable distributed systems; Kestrel: 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.
DistributedLog and Kestrel can be categorized as "Message Queue" tools.
Some of the features offered by DistributedLog are:
- High Performance
- Durable and Consistent
- Efficient Fan-in and Fan-out
On the other hand, Kestrel provides the following key features:
- Written by Robey Pointer
- Starling clone written in Scala (a port of Starling from Ruby to Scala)
- Queues are stored in memory, but logged on disk
DistributedLog and Kestrel are both open source tools. Kestrel with 2.8K GitHub stars and 326 forks on GitHub appears to be more popular than DistributedLog with 2.25K GitHub stars and 283 GitHub forks.
