The Difference Between Change Data Capture and Event Streams
A lot of the conversation around real time data has, for the most part, been driven by event streams. When you think about log streaming or iot data, a lot of these data streams are argubly relatively straightforward ride. And in some cases, systems genuinely process deletsand and we want to deal with those. Some othe use cases you want to look at it as an incremeble stream of changes. It's not like we're going back and updating historical data poins. But for many use cases, you also want to get the current state of the data.

Summary
Data integration from source systems to their downstream destinations is the foundational step for any data product. With the increasing expecation for information to be instantly accessible, it drives the need for reliable change data capture. The team at Fivetran have recently introduced that functionality to power real-time data products. In this episode Mark Van de Wiel explains how they integrated CDC functionality into their existing product, discusses the nuances of different approaches to change data capture from various sources.

- RudderStack helps you build a customer data platform on your warehouse or data lake. Instead of trapping data in a black box, they enable you to easily collect customer data from the entire stack and build an identity graph on your warehouse, giving you full visibility and control. Their SDKs make event streaming from any app or website easy, and their state-of-the-art reverse ETL pipelines enable you to send enriched data to any cloud tool. Sign up free… or just get the free t-shirt for being a listener of the Data Engineering Podcast at dataengineeringpodcast.com/rudder.
- Data teams are increasingly under pressure to deliver. According to a recent survey by Ascend.io, 95% in fact reported being at or over capacity. With 72% of data experts reporting demands on their team going up faster than they can hire, it’s no surprise they are increasingly turning to automation. In fact, while only 3.5% report having current investments in automation, 85% of data teams plan on investing in automation in the next 12 months. 85%!!! That’s where our friends at Ascend.io come in. The Ascend Data Automation Cloud provides a unified platform for data ingestion, transformation, orchestration, and observability. Ascend users love its declarative pipelines, powerful SDK, elegant UI, and extensible plug-in architecture, as well as its support for Python, SQL, Scala, and Java. Ascend automates workloads on Snowflake, Databricks, BigQuery, and open source Spark, and can be deployed in AWS, Azure, or GCP. Go to dataengineeringpodcast.com/ascend and sign up for a free trial.

- Your host is Tobias Macey and today I’m interviewing Mark Van de Wiel about Fivetran’s implementation of change data capture and the state of streaming data integration in the modern data stack
Interview
- Introduction
- How did you get involved in the area of data management?
- What are some of the notable changes/advancements at Fivetran in the last 3 years?
- How has the scale and scope of usage for real-time data changed in that time?
- What are some of the differences in usage for real-time CDC data vs. event streams that have been the driving force for a large amount of real-time data?
- What are some of the architectural shifts that are necessary in an organizations data platform to take advantage of CDC data streams?
