A 3-day bug hunt on a 3-person team costs up to €7,200 in lost engineering time. This workshop teaches you to prevent that — unit tests, data tests, and integration tests for PySpark and Databricks Lakeflow, including Spark Declarative Pipelines.
Recently I wrote posts about idempotent consumer pattern analyzing Apache Camel implementation and CDC applied on NoSQL stores. After that I had an idea, what happened if we would mix both of them?
In my previous post I presented an implementation of idempotent consumer pattern with Apache Cassandra CDC. One of drawbacks of that solution was the necessity of producing the messages with slower lightweight transactions. In this post I will show you how to do the same with AWS DynamoDB streams and without that constraint.
