rdsync
Rdsync is a redis high-availability tool. It uses a patched redis version to make a cluster or sentinel-like setup less prone to data loss.
Limitations and requirements
- Patched redis (patches for redis 7.2 are included in this repo)
- ZooKeeper as DCS
- Single redis instance per host
- In clustered setup each shard must have it's own DCS prefix
- Client application must use
WAITQUORUM
command to make data loss less usual (check jepsen test for example).
Try it out
- You will need a linux vm with gnu make, docker, docker-compose and go >1.21 installed.
- Use
make start_sentinel_env
to start an environment with senticache - Or
make start_cluster_env
to start an environment with single shard of clustered setup - Run
make clean
to drop containers and network
