Apache Flink is a distributed stream processing framework that processes unbounded streams and bounded batch data with the same API. Its core features are event-time windowing, exactly-once state consistency, and failure recovery through checkpoints, and it is combined with messaging systems such as Kafka to build real-time pipelines. Unlike the micro-batch approach of Spark Streaming, it processes data record by record, giving it low latency.
