A distributed implementation of Redis compatible layer based on TiKV

Status

Active development, not ready for production. We welcome any form of contributions!

Our goal is to build a solid NoSQL database aiming to run in the production environment. We are using Titan in production inside Meitu now. If you cannot wait to experiment it in the production environment, feel free to contact us for technical supporting.

Features

  • Completely compatible with redis protocol
  • Full distributed transaction with strong consistency
  • Multi-tenancy support
  • No painful scale out
  • High availability

Thanks TiKV for supporting the core features
