can kafka be used for batch processing?

Need for Batch Consumption From Kafka Data ingestion system are built around Kafka. They are followed by lambda architectures with separate pipelines for real-time stream processing and batch processing. Real-time stream processing pipelines are facilitated by Spark Streaming, Flink, Samza, Storm, etc.

Batch vs. Real Time Data Processing. Batch data processing is an efficient way of processing high volumes of data is where a group of transactions is collected over a period of time. ... In contrast, real time data processing involves a continual input, process and output of data.

Abstract. Our recent research (Budish, Cramton, and Shim 2013) proposes frequent batch auctions—uniform-price sealed-bid double auctions conducted at frequent but discrete time intervals—as a market design alternative to continuous-time trading in financial markets.

Apache Beam is an open source unified programming model for defining and executing both batch and streaming data-parallel processing pipelines. Beam provides a portable API layer for describing these pipelines independent of execution engines (or runners) such as Apache Spark, Apache Flink or Google Cloud Dataflow.

Just like multiple producers can write to the same topic, we need to allow multiple consumers to read from the same topic, splitting the data between them. Kafka consumers are typically part of a consumer group .

Kafka act as the central hub for real-time streams of data and are processed using complex algorithms in Spark Streaming. Once the data is processed, Spark Streaming could be publishing results into yet another Kafka topic or store in HDFS, databases or dashboards.

Batch processing is a technique in which an Operating System collects the programs and data together in a batch before processing starts. An operating system does the following activities related to batch processing − The OS defines a job which has predefined sequence of commands, programs and data as a single unit.
