go-smr

Simple application that replicates a key-value store using the Raft protocol. This application uses the Hashicorp implementation of the Raft protocol.

Usage:

First execute:

go build

This will create a local executable with name smr. Then, with 3 terminal tabs open, execute on each one:

./smr -addr=127.0.0.1:8080

Will create an HTTP server on port 8080 and will create a Raft node on port 9090.

./smr -addr=127.0.0.1:8081 -raft=127.0.0.1:9091

Will create an HTTP server on port 8081 and will create a Raft node on port 9091.

./smr -addr=127.0.0.1:8082 -raft=127.0.0.1:9092

Will create an HTTP server on port 8082 and will create a Raft node on port 9092.

Those are the default configuration, that can be found on the file config.json. Now with the servers available, is possible to execute requests, like:

curl 'localhost:8081/set?key=Fuck&value=Police'

Sending a request to the HTTP server on port 8081 to associate the key Fuck with value Police. Now to retrieve a value just execute:

curl 'localhost:8080/get?key=Fuck'

The value defined on server 8081 is now available on server 8080.
