Tumbling Window trigger vs Scheduled trigger

Question

What is the core difference between Tumbling Window trigger and Scheduled trigger?

Tuhin Paul · Answer

Tumbling Window Trigger: A Tumbling Window trigger processes events in a non-overlapping fixed-size window. Once a window completes it triggers the next window’s processing. Tumbling windows are ideal for periodic batch processing of data where each window is completely independent of the others. Usage : Typically used when you need to process events in fixed time intervals without overlap e.g. processing logs every 10 minutes regardless of when the last event occurred. Scheduled Trigger: A Scheduled trigger allows you to run an operation at specific predefined intervals (e.g. every hour day week). It does not consider windows but rather runs based on a set schedule regardless of data arrival. Usage : Used when you need the process to run at specific times or intervals like running a report every day at midnight regardless of when new data arrives.

The core difference between a Tumbling Window trigger and a Scheduled trigger lies in how they handle time intervals and the execution of tasks. Both are used in automation and orchestration tools like Azure Data Factory but they serve different purposes and have distinct behaviors. Here's a breakdown of their differences: Core Differences: Feature Tumbling Window Trigger Scheduled Trigger Time Intervals Fixed non-overlapping contiguous windows Customizable can overlap Reprocessing Supports reprocessing of failed windows No built-in reprocessing State Management Stateful (tracks each window) Stateless (no tracking of individual runs) Overlapping Runs No overlapping Runs can overlap Use Case Data aggregation ETL pipelines Periodic tasks backups reports Thank you.
