What is Flink streaming?
Apache Flink is an open-source, unified stream-processing and batch-processing framework developed by the Apache Software Foundation. Flink provides a high-throughput, low-latency streaming engine as well as support for event-time processing and state management.
What is Apache Flink good for?
Flink is a distributed processing engine and a scalable data analytics framework. You can use Flink to process data streams at a large scale and to deliver real-time analytical insights about your processed data with your streaming application.
Is Flink good for real time processing?
Flink is a true streaming engine, can process live streams in the sub-second interval. Flink’s APIs are developed in a way to cover all the common operations, so programmers can use it efficiently. Apache Flink provides high performance and Low latency without any heavy configuration.
What is watermark in Flink?
A Watermark is essentially a timestamp. When an Operator in Flink receives a watermark, it understands(assumes) that it is not going to see any message older than that timestamp. Hence watermark can also be thought of as a way of telling Flink how far it is, in the “EventTime”.
Why do we need Flink?
Built as open source software by an open community, Flink provides stream processing for large-volume data, and it also lets you handle batch analytics, with one technology. In addition, the will book help you understand Flink’s technology and how it tackles the challenges of stream processing.
