A fast and lightweight Redis Cluster Proxy for Redis 3.0 with cluster mode enabled focused on Linux >= 3.9. Clients designed for normal mode Redis can still be used through the proxy. Redirection errors are handled and slot map is cached in proxy.
Build from source:
$ makeBuild in debug mode:
$ make debugConfiguration file:
# corvus.conf
# binding port
bind 12345
# redis cluster nodes, comma separated list, can supply only one node
node localhost:8000,localhost:8001,localhost:8002
# threads share the same binding port using SO_REUSEPORT
thread 4
# log level, available values: debug, info, warn, error
# if not supplied or wrong value `info` is used
loglevel info
# whether log to syslog
syslog 0
Run proxy:
./src/corvus corvus.confAll single key commands are supported. Commands performing complex multi-key operations like unions or intersections are available as well as long as the keys all belong to the same node.
