dbt Meets Apache Flink: One Workflow for Data Engineers

Data engineers managing batch SQL pipelines on Snowflake, BigQuery, and increasingly Databricks, and streaming pipelines on Apache Flink face a familiar problem: two toolchains, two skill sets, two CI/CD pipelines.dbt is now extending into stream processing. This post explains what that means in practice, why it matters for data engineering teams, and what a concrete implementation looks like with Apache Flink on Confluent Cloud.

Data Streaming Meets the Lakehouse

Data lakes promised to solve the enterprise data problem. The reality has been messier. Batch pipelines produce stale information, and analytical workloads run hours after the business event occurred. By the time a query runs, the window for action is often already closed.

How to Perform Response Verification in REST-Assured Java for API Testing: Part 2

API testing is an essential part of modern software development. While sending requests and receiving responses is straightforward, the real value of API automation comes from response verification. A test is meaningful only when it validates that the API returns the correct data, structure, status codes, and business rules.

In Java-based API automation, REST Assured combined with Hamcrest Matchers provides a clean and expressive way to verify API responses. These matchers help testers write readable assertions that validate numbers, strings, arrays, JSON objects, and collections with minimal code.

Stream Processing on the Mainframe With Apache Flink: Genius or a Glitch in the Matrix?

Running Apache Flink on a mainframe sounds odd at first. A modern stream processing engine on a platform most people call legacy? But take a closer look. It is not only possible. It might be a smart move for some of the largest financial institutions in the world. This post explores why some enterprises want Apache Flink on the mainframe, how it could work, and whether it is a brilliant innovation or a technical detour.
