Publisher Subscriber Pattern

How to Run and test?

• Compile all source files using javac *.java
• The ShardCoord is responsible for running all ShardRegion instances.
• Run RMI registry using rmiregistry.
• Create a new terminal tab using Ctrl+Shift+T for each of the below commands.
• Run Server using java Server. Run Publisher using java Publisher. Run Subscribers using java Subscriber multiple times. You can subscribe to a topic in a server using "S topic_name" and unsubscribe using "U topic_name". To send to a particular topic from Publisher, use "topic_name message".
• Alternatively, you can also create and run the test cases using java Verifier. This will create the test cases in tests/input.txt. It will also then run the test cases using our code and produce the output in logs/ directory. It will also create expected_output for the test cases in tests/expected_output/ directory. It will then diff the contents of files in logs/ and tests/expected_output/ to see if correct result is being produced and will prompt if all test cases have passed or not.
