wijzigingsstroom

A wijzigingsstroom, or change stream, is a mechanism used in software development and data management to track and propagate changes made to data. It typically involves capturing a chronological sequence of modifications applied to a dataset, such as insertions, updates, and deletions. This stream of changes can then be used for various purposes, including replication, auditing, and real-time data synchronization.

Different systems implement change streams in distinct ways. Some might record every single alteration in a log, while others might focus on the net effect of a series of operations. The granularity of the recorded changes can vary, from individual field modifications to entire record replacements. The primary goal of a wijzigingsstroom is to provide a reliable and efficient way to keep different data stores or systems consistent with each other.

In distributed systems, wijzigingsstromen are crucial for maintaining data integrity and availability. For instance, a database might publish its changes to a change stream, allowing other services to subscribe and react to these updates. This enables patterns like event sourcing, where the change stream serves as the source of truth for the application's state. Furthermore, change streams can be employed for data warehousing and business intelligence, facilitating the incremental loading of data and enabling near real-time analytics. The concept is fundamental to building resilient and scalable data-driven applications.
