Change Data Capture at Netflix with DBLog

Netflix Tech Blog has a post on relatively new change data capture tool called DBLog.

When I worked at Netflix a while ago, they also had a hacky tool that would find changes in one database and copy them to another. Although hacky, it was effective, and they key thing was that it only copied changed rows in a window older than 10 minutes. For that use case, most update churn was under 5 minutes, so older rows were already quiescent. 🙂 DBLog: A Generic Change-Data-Capture Framework
