Can Hadoop Do real-time processing?

Can Hadoop Do real-time processing?

Hadoop was never built for real-time processing. Hadoop initially started with MapReduce, which offers batch processing where queries take hours, minutes or at best seconds. This is and will be great for complex transformations and computations of big data volumes.

What is real time data processing?

Real-time data processing is the quickest data processing technique that executes data in a short period of time and provides the most accurate output. Real-time data processing deals with the inputted data that are captured in real-time and provides an automated response based on the streams of data.

What is Hadoop real-time?

Hadoop was initially designed for batch processing. That means, take a large dataset in input all at once, process it, and write a large output. The very concept of MapReduce is geared towards batch and not real-time.

Is Hadoop best for real-time streaming of data?

Limitations of Real-Time Streaming and Analytics Compatibility: In the case of historical big data analytics, Hadoop is the most widely used tool, but in the case of streaming and real-time data, it is not. The better options are spark streaming, Apache Samza, Apache Flink, or Apache Storm.
