SImple Key-value store, Impefect, but Distributed

An exercise on implementing a distributed key-value store in Haskell.

This project can be built using stack.

To run a node without installing the binaries you can use stack:

stack exec skid -- -i -p 3023

The command above will spawn a node on the local-host, on port 3023, and start a REPL to interact with the key-value store. The following commands are supported in this simple REPL:

• peers: list the known peers.
• get k: get the value (if any) associated with the key k.
• put k v: add the pair (k, v) to the map.
• q or quit: quit the REPL. Note that this won't stop the node. Just use Ctrl+C for that purpose.

To run a node in non-interactive mode omit the flag -i.
