Apache Flink
An open-source stream processing framework originally initiated by the Technical University of Berlin and donated to the Apache Software Foundation. It serves as an industry standard for large-scale real-time data processing, with a core design centered on stateful stream computation, checkpoint mechanisms, and fault recovery.

Oracle, Snowflake, Trino/Presto, and Apache Flink have provided MATCH_RECOGNIZE support, while PostgreSQL, MySQL, and others have not yet natively supported the syntax
The MATCH_RECOGNIZE implementation in Apache Flink differs from that in batch-processing databases, for example in its handling mechanisms for unbounded streams and the definition of timeout semantics
The Uber engineering blog disclosed that its risk control system uses a real-time stream processing architecture based on Apache Kafka and Apache Flink, combined with graph neural networks for fraud detection and gradient boosted trees for risk scoring.
Kappa架构基于统一的流处理引擎（如Apache Flink）处理实时和历史数据，作为Lambda架构的替代方案，通过减少双路径维护成本降低系统复杂度
