Polling Based Automation
Polling based automation is a software development methodology where a system or script repeatedly checks (polls) a data source, such as an API endpoint, database, or file system, at regular intervals to detect changes or new data. It involves continuously querying a target to monitor for updates, events, or conditions, and then triggering automated actions in response. This approach is commonly used for tasks like data synchronization, monitoring systems, or handling asynchronous operations where real-time event-driven mechanisms are not available.
Developers should use polling based automation when building systems that need to react to changes in external data sources without built-in event notifications, such as legacy APIs, file-based integrations, or simple monitoring tools. It is particularly useful in scenarios where low latency is not critical, resources are limited, or when implementing lightweight automation scripts, such as checking for new files in a directory or polling a REST API for status updates. However, it can be inefficient for high-frequency updates due to constant resource usage and potential delays.
