rdsync

Rdsync is a valkey high-availability tool. It uses a patched valkey version to make a cluster or sentinel-like setup less prone to data loss.

Limitations and requirements

• Patched valkey (patches for valkey 8.0 are included in this repo)
• ZooKeeper as DCS
• Single valkey 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 >1.22 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
