Consuming CDC with Java and Go
Blog post from ScyllaDB
Change Data Capture (CDC) in ScyllaDB allows users to track and respond to data changes within a cluster, with ScyllaDB 4.3 marking CDC as production-ready. To facilitate the development of applications that read from ScyllaDB's CDC, libraries for Java and Go have been released, catering to both established Java users and those preferring Go for its concurrency and performance benefits. The CDC mechanism involves CDC log tables, which are linked to base tables and record data modifications such as insertions, updates, or deletions. These libraries abstract the complexities of managing streams and generations, ensuring ordered processing of changes and accommodating topology changes within the cluster. Applications can be written to utilize these libraries, which handle the intricacies of the CDC log format, allowing developers to focus on business logic. The blog post provides guidance on using these libraries, alongside examples and further resources, empowering developers to build efficient, real-time change-tracking applications with ScyllaDB.
