Change Data Capturing - How Do You Apply Transformations on the Data?
Cedecevet acknowledges by far the easiest, and from our perspective, the proposed approach is to essentially take a straight copy of sores tables that you're interested in into the destination with minimal transformations. Instead of physically dileting a row an naroga deleted on the sorce, we mark it as deleted instead. We can align the chainge data capture with the state of the destination, and thessentially pick up continue from there. And then will have some nice capabilities, like lineage charts that eventually can show you, based on the data in the destination, where the ta data comeo.

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. If you’re a data engineering podcast listener, you get credits worth $5,000 when you become a customer.
- 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?
- What are some of the shifts in e.g. cloud data warehouses that have happened/are happening to allow for ingestion and timely processing of these data feeds?
- What are some of the different ways that CDC is implemented in different source systems?
- What are some of the ways that CDC principles might start to bleed into e.g. APIs/SaaS systems to allow for more unified processing patterns across data sources?
- What are some of the architectural/design changes that you have had to make to provide CDC for your customers at Fivetran?
- What are the most interesting, innovative, or unexpected ways that you have seen CDC used?
- What are the most interesting, unexpected, or challenging lessons that you have learned while working on CDC at Fivetran?
- When is CDC the wrong choice?
