Logger: Low level system design

• A logger implementation designed for multithreaded environments, dealing with concurrency and locking mechanisms.

System Design

• Sink.java is a base class which can be inherited by any kind of logging service (File, Memory, Database)
• FileSink.java log the information in the specific file.
• LogController.java: Responsible for calling the sink service. Maintains the queue of log requests that cannot be served currently. As one log request get's completes, request is been fetched from queue.
• Process.java, starts executing the log request on a separate thread using completable future.
• Manager.java is the driver class.

Concepts

• Completable Future: are used to perform asynchronous computations, specifically ending processes without blocking the main thread. supplyAsync - It will execute the steps in a separate thread.

How to run:

1. It will compile the java code: javac src/Manager.java
2. Run using: java src/Manager
