PaxosStore is a distributed database system developed by Tencent, inspired by Google MegaStore and used in WeChat production for core backend storage. The open-source release provides two Paxos consensus libraries, Certain and PaxosKV, implementing the leaseless consensus layer described in their VLDB 2017 paper.
Use cases
- build a strongly consistent distributed key-value store
- implement Paxos consensus replication in C++
- study production-grade consensus algorithms from WeChat
- achieve high-availability storage across thousands of machines
- replicate data with PaxosLog for a database backend
When to choose
- you need battle-tested Paxos consensus libraries in C++
- you are building a custom distributed database with strong consistency
- you want to study a proven large-scale consensus implementation
When to avoid
- you need a ready-to-run general-purpose database out of the box
- you want a maintained project with active releases and community support
- you need SQL or rich data structures, which were only planned and never fully open-sourced
