![]() With CDC, you can easily avoid issues like dual writes to, as opposed to updating resources concurrently and precisely. When you update a source database- usually a relational database such as PostgreSQL, MySQL, Oracle, or Microsoft SQL Server- you might have to update various related resources such as a search index and a cache. Streaming updates of your search indexes.Streaming updates to your online data stores for your production Machine Learning models.Anomaly detection and streaming analytics.Since you are continuously streaming data from your database to your Data Warehouse, the data in your house needs to be up-to-date, allowing you to generate real-time insights, giving you a considerable edge over your competitors since you are making business decisions on fresher data.Īpart from this, you can also leverage CDC for the following supplementary applications:.Although changefeeds aren’t free, they are much cheaper and are spread evenly throughout the day. Therefore, you don’t have to worry about spiky behaviors in the load. CDC does not need you to perform high load queries on a periodic basis.Since the data is sent continuously in CDC and in much smaller batches, you don’t have to provision as much network to make it work, plus, you can save money on network costs.You can leverage CDC to stream data from your primary database to your Data Warehouse to solve the following problems: With the help of CDC, companies deliver new data changes to BI (Business Intelligence) tools and team members in real-time, keeping them up-to-date. It allows Data Warehouse or Databases to stay active for some action to perform as soon any Change Data Capture occurs.ĬDC is a Data Integration approach that allows high-velocity data to achieve reliable, low latency, and scalable data replication using fewer computation resources. It excludes the process of bulk data loading by implementing incremental loading of data in nearly real-time. Companies need access to real-time data streams for Data Analytics. It triggers the event associated with data so that a particular action will be taken for any Change Data Capture. What is the Difference between CDC and SCD?Ĭhange Data Capture (CDC) is a collection of software design patterns used to detect any data change in the database.Change Data Capture Real-World Use Cases.Business Benefits of Change Data Capture. ![]() Change Data Capture in Distributed System. ![]()
