If you’ve worked in the data world for even a year, someone has asked you to build a real-time dashboard. I had this happen nearly day one of my first job. And of course I said...no problem! One possible choice is a method called change data capture, also known as CDC. I have seen companies employ multiple ways to use CDC or CDC-like approaches to pull data from databases like Postgres or MongoDB. This can range from using triggers to reading logs. Of course, this focuses on the analytical component as many companies use CDC to replace or supplement traditional ETL/ELT. But CDC can also be a great way to understand your database and its structure. Databases abstract much of what they do to manage and process large volumes of data quickly. Before going down that rabbit hole, let’s dive into what CDC is and why companies use it. https://lnkd.in/gUYWABxq
