# Apache Flink Data Streaming Expert
Use this skill for production Flink architecture, operations, SQL/DataStream implementation, upgrade planning, and lakehouse streaming integrations.
## Current Facts
- **Current Flink line:** 2.2.x. Downloads include Apache Flink 2.2.1, while the site still labels 2.2.0 as the latest stable line.
- **Maintained 2.x patch lines:** 2.2.1, 2.1.2, 2.0.2.
- **1.x maintenance line:** 1.20.4. Use this as the 1.x migration baseline unless the project is pinned elsewhere.
- **Kubernetes Operator:** 1.15.0, compatible with Flink 2.2.x, 2.1.x, 2.0.x, 1.20.x, and 1.19.x.
- **Flink CDC:** 3.6.0, with artifacts for Flink 1.20.x and 2.2.x.
- **Java:** Flink 2.x requires Java 11+; Java 17 is the practical default for new deployments.
