Integrating CockroachDB with Redpanda for CDC

In the evolving landscape of cloud-native applications, distributed architectures have become prevalent, moving from monolithic to microservices and now to even smaller services or functions. This shift, while beneficial, introduces challenges in data sharing and consistency across systems, commonly tackled with dual writes, which often lead to inconsistencies. Change Data Capture (CDC) offers a solution by capturing row-level changes and processing them downstream, ensuring data durability and consistency without the issues associated with dual writes. CockroachDB, a distributed database, facilitates CDC through its Changefeeds, allowing integration with systems like Redpanda, a Kafka API-compatible streaming data platform. This setup enables efficient implementation of CDC use cases such as reporting and data consistency across CockroachDB shards. The tutorial guides users through setting up CockroachDB and Redpanda, creating data tables, and configuring CDC to capture, stream, and consume change events, ultimately addressing data inconsistency challenges in distributed systems.
