SeaweedFS - Simple and highly scalable distributed file system

•    Go

SeaweedFS is a simple and highly scalable distributed file system. There are two objectives: to store billions of files! to serve the files fast! Instead of supporting full POSIX file system semantics, SeaweedFS choose to implement only a key~file mapping. Similar to the word "NoSQL", you can call it as "NoFS".

huststore - High-performance Distributed Storage

•    C

huststore is a open source high performance distributed database system. It not only provides key-value storage service with extremely high performance, up to 100 thousand QPS, but also supports data structures like hash, set, sorted set, etc. Also, it can store binary data as value from a key-value pair, and thus can be used as an alternative of Redis.In addtion, huststore implements a distributed message queue by integrating a special HA module, features including message Push Stream, and message Publish-SubScribe, these features can be used as replacements of the corresponding features in rabbitmq and gearman.

braft - An industrial-grade C++ implementation of RAFT consensus algorithm based on brpc, widely used inside Baidu to build highly-available distributed systems

•    C++

An industrial-grade C++ implementation of RAFT consensus algorithm and replicated state machine based on brpc. braft is designed and implemented for scenarios demanding for high workload and low overhead of latency, with the consideration for easy-to-understand concepts so that engineers inside Baidu can build their own distributed systems individually and correctly. Build brpc which is the main dependency of braft.

dragonboat - A feature complete and high performance multi-group Raft library in Go.

•    Go

Dragonboat is a high performance multi-group Raft consensus library in Go with C++11 binding support. Consensus algorithms such as Raft provides fault-tolerance by alllowing a system continue to operate as long as the majority member servers are available. For example, a Raft cluster of 5 servers can make progress even if 2 servers fail. It also appears to clients as a single node with strong data consistency always provided. All running servers can be used to initiate read requests for aggregated read throughput.
