That doesn’t mean it lags behind when data has to be written to (and fetched from) disk, as it is the world record holder for large-scale on-disk sorting.

Speed – Spark can execute batch processing jobs 10 to 100 times faster than MapReduce.

One of the key differentiators for Spark is its ability to hold intermediate results in-memory itself, rather than writing back to disk and reading from it again, which is critical for iteration based use cases. It essentially takes MapReduce to the next level with a performance that is several times faster.

In a short time of 2 years since its initial release (May 2014), it has seen wide acceptability for real time, in-memory, advanced analytics – owing to its speed, ease of use and the ability to handle sophisticated analytical requirements. It is written in Scala, Java, R and Python and gives programmers an Application Programming Interface (API) built on a fault tolerant, read only multiset of distributed data items. Spark is an open source, cluster computing framework which has a large global user base. Our two topics for today – Apache Spark and Apache Flink – attempt to answer that question and more. Prepare for Your Next Big Data Job Interview with Kafka Interview Questions and Answers In the present decade, the problem statement has shifted to “What to do with huge chunks of data?” Data Analytics emerged as the ultimate goal but before that, a lot of work needs to be done to integrate data stored in different formats at different sources and prepare it for processing and analytics, which is a demanding task. However, new age storage solutions such as Cloud Computing has revolutionized the industry and presented the best possible solution. Sudden rise of social media did not make their tasks any easier. “How to store these enormous amounts of data?” was a problem statement that kept the tech geeks busy for most part of previous decade.

Apache Spark and Flink may seem similar to someone who has not worked with either of these and is only familiar with Hadoop, and it is obvious that they will feel that the development of Apache Flink is mostly superfluous. There is a common misconception that Apache Flink is going to replace Spark or is it possible that both these big data technologies ca n co-exist, thereby serving similar needs to fault-tolerant, fast data processing. ProjectPro is the only online platform designed to help professionals gain practical, hands-on experience in big data, data engineering, data science, and machine learning related technologies.Īpache Spark and Apache Flink are both open- sourced, distributed processing framework which was built to reduce the latencies of Hadoop Mapreduce in fast data processing.
