WebMar 7, 2016 · No need of Batch Size in Flink Spark streaming needs batch size to be defined before any stream processing. It’s because spark streaming follows micro batches for stream processing which is also known as near realtime . But flink follows one message at a time way where each message is processed as and when it arrives. WebUse cases like fraud detection, real-time alerts in healthcare and network attack alert require real-time processing of instant data; a delay of even few milliseconds can have a huge impact. An ideal tool for such real time use cases would be the one, which can input data as stream and not batch. Apache Flink is that real-time processing tool.

Webbatch.size The producer will attempt to batch records together into fewer requests whenever multiple records are being sent to the same partition. This helps performance on both the client and the server. This configuration controls the default batch size in bytes. No attempt will be made to batch records larger than this size.
