Case study: How we used feature flags to migrate from MongoDB to PostgreSQL with ZERO downtime at a fintech company. Gradual rollout with instant rollback capability = no customer impact. Learn this technique and more.

I've shared code examples for implementing feature flags in Java, React, and Node.js - from basic toggles to sophisticated experimentation platforms. Plus best practices from implementing them across multiple organizations.

Feature flags create decision points in code that determine whether a feature is enabled for specific users. They serve different purposes: Release Flags, Experiment Flags, Ops Flags, and Permission Flags.

🚀 Feature flags have transformed how engineering teams deploy and test new functionality. At Spotify, they reduced deployment risks by 80%! Netflix runs 250+ experiments simultaneously with them. Here's how to implement them effectively.

🧠 Advanced patterns covered: handling schema evolution, optimizing for large change volumes, and implementing exactly-once processing semantics. Check it out!

💡 The post includes practical code examples for real-world use cases like real-time analytics dashboards, data quality monitoring, and implementing SCD Type 2 dimensions.

⚡️ Incremental processing can dramatically reduce compute costs and processing time. In this guide, I walk through enabling CDF, reading change data, and building complete pipelines.
