  • Fundamental knowledge of real-time Data Streaming. 

What are Stream Processing Systems?

Stream Processing is a way of continuously obtaining real-time data in the form of data streams from external data sources. The stream processing method frequently involves performing numerous operations on an incoming series of data (the “data stream“), which can be done serially, in parallel, or both. Such workflow is collectively called a Stream Processing Pipeline since it encompasses the generation of stream data, processing the data, and delivering the data to a final destination. Furthermore, real-time stream processing is critical for dealing with massive amounts of live data gathered from a variety of sources, such as online transactions, in-game player actions, sensors, system logs, and much more.

In order to implement Stream Processing operations, real-time data must be handled sequentially and progressively on a record-by-record basis or over sliding time periods, which can be further used for a range of Analytics tasks such as correlations, aggregations, filtering, and sampling. The information derived from such analysis provides organizations with visibility into many aspects of their business and customer activity, such as service usage (for metering/billing), website clicks, server activity, geo-location of devices, and physical goods, allowing them to respond quickly to emerging situations.

Apache Kafka is an open-source and distributed Stream Processing Platform that receives, stores, organizes, and delivers data across various end-users or downstream applications. In other words, Apache Kafka is a community-driven event streaming technology that can handle trillions of events each day. Kafka was originally envisioned as a messaging queue, but it is now built on an abstraction of a distributed commit log.

Apache Kafka offers users Kafka Streams, which is a Java API for implementing stream processing operations. This API allows developers to implement data processing techniques like filtering, joining, aggregating, and grouping without writing any code. Since it is a Java library, it is simple to integrate with any services you use and transform them into powerful, scalable, fault-tolerant systems.

Apache Kafka is used in developing both real-time streaming data pipelines and applications. A data pipeline reliably processes and transports data from one system to another, whereas a streaming application consumes data streams. For example, if you want to build a data pipeline that takes in user activity data for tracking how people use your website in real-time, you’d use Kafka to ingest and store streaming data while sending requests to the apps that run the data pipeline. Because of its effective features and functionalities, Apache Kafka is being used by more than 80% of fortune 500 companies, including Netflix, Uber, Cisco, and Airbnb. 

Apache Kafka is absolutely free to download and use as it is one of the popular open-source stream processing systems. However, to use Kafka connectors that come along with the Confluent subscription, you have to pay based on the basic, standard, and dedicated plans.

Tired of writing code to stream your data from Kafka to a Data Warehouse? Use Hevo Data, an Automated No-code Data Pipeline, to replicate the data from your Apache Kafka Source to your Destination. Hevo loads the data onto the desired Data Warehouse & transforms it into an analysis-ready form without having to write a single line of code.
