Multi-threaded key-value store (RPC/RMI)

A client-server architecture that communicates with Remote Procedure Calls (RPC). Implemented using Java RMI. The server is multi-threaded such that it can handle multiple outstanding client requests at once.

It's set up to allow multiple concurrent clients to communicate with it and perform three basic operations:

• PUT(key, value)
• GET(key)
• DELETE(key)

Usage (locally):

1. Open up two terminal windows and navigate to /Project2/src
2. In one window, type javac server/*.java utils/*.java (hit ↩), followed by java server.Main <Port#>, where <Port#> is the port number the registry is located at (hit ↩)
3. The server is now running
4. In the other window, type javac client/*.java utils/*.java (hit ↩), followed by java client.Main <Port#>, where Port# is the server's registry's port number (it has to match the server's) (hit ↩)
5. The client is now running
6. The predefined protocol is:
   • PUT:key:value(hit ↩)
   • GET:key(hit ↩)
   • DELETE:key(hit ↩)
7. To shut down the application, type stop(hit ↩) or shutdown(hit ↩)
