Tidis is a Distributed NoSQL database, providing a Redis protocol API (string, list, hash, set, sorted set), written in Go.
Tidis is like TiDB layer, providing protocol transform and data structure compute, powered by TiKV backend distributed storage which use Raft for data replication and 2PC for distributed transaction.
- Redis protocol compatible
- Linear scale-out ability
- Storage and computation separation
- Data safety, no data loss, Raft replication
- Transaction support
This repo is WIP
now and has lots of work to do, and for test only.
Any pull requests are welcomed.
git clone https://github.com/yongman/tidis.git
cd tidis && make
Use docker run tikv
for test, just follow PingCAP official guide, you just need to deploy PD and TiKV servers, Tidis will take the role of TiDB.
