Cherami: Uber Engineering’s Durable and Scalable Task Queue in Go - Uber Engineering Blog

a competing-consumer messaging queue that is durable, fault-tolerant, highly available and scalable. We achieve durability and fault-tolerance by replicating messages across storage hosts, and high availability by leveraging the append-only property of messaging queues and choosing eventual consistency as our basic model. Cherami is also scalable, as the design does not have single bottleneck. [...]
Cherami is completely written in Go, a language that makes building highly performant and concurrent system software a lot of fun. Additionally, Cherami uses several libraries that Uber has already open sourced: TChannel for RPC and Ringpop for health checking and group membership. Cherami depends on several third-party open source technologies: Cassandra for metadata storage, RocksDB for message storage, and many other third-party Go packages that are available on GitHub. We plan to open source Cherami in the near future.
