The Python API allows you to build scalable data pipelines using either a high-level Table API (similar to SQL or working with tabular data) or a lower-level DataStream API for fine-grained control over state and time semantics. It runs in common cluster environments and executes computations at in-memory speed across any scale.\n\nThe package depends on a substantial stack: py4j for JVM interop, apache-beam, and data-handling libraries like numpy, pandas, and pyarrow. It supports Python 3.9\u20133.12 and has been in production use since first release in 2020. The Table API suits exploratory data analysis and relational queries, while the DataStream API targets complex stream processing use cases requiring explicit state management.","worth_installing":"Yes, if you need a mature, production-grade distributed stream or batch processing framework in Python and can manage the JVM dependency and substantial runtime dependency footprint. Active maintenance, permissive license, and support for Python 3.9\u20133.12 make it solid for large-scale data pipelines. Not recommended for lightweight, single-machine workloads or if you want to avoid Java runtime overhead."},"id":"apache-flink","links":{"html":"https://skillfed.io/packages/apache-flink","md":"https://skillfed.io/packages/apache-flink.md","pypi":"https://pypi.org/project/apache-flink/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-06-21","license_spdx":null,"license_treatment":"permissive","name":"apache-flink","python_support":"supports_current","summary":"Apache Flink Python API"},"popularity":{"monthly_downloads":214134,"position":9423,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.3.0"}
