File-Based Communication
File-based communication is a method of inter-process or inter-system communication where data is exchanged through files stored on a filesystem. It involves one process writing data to a file and another process reading from that file, often using agreed-upon formats like CSV, JSON, or XML. This approach is commonly used in batch processing, data pipelines, and legacy systems where asynchronous or decoupled communication is needed.
Developers should learn file-based communication for scenarios requiring simple, persistent data exchange without real-time constraints, such as log aggregation, ETL (Extract, Transform, Load) processes, or integrating with older systems that lack modern APIs. It's useful when dealing with large datasets that need to be processed in batches or when building fault-tolerant systems where files can serve as a durable message queue.
