Apache Spark hottest New Trends | What is Apache Spark? A unified platform for Data Management 2020
Apache Spark is one of the hottest new trends in the technology domain.
It is the framework with probably the highest potential between Big Data and ML.
It runs fast (up to 90x faster than traditional Hadoop MapReduce due to in-memory operation, offers robust, distributed, fault-tolerant data objects, and integrates beautifully with the world of ML and graph analytics through supplementary packages like Mlib and GraphX.
The best part about using Spark is that you can write Spark apps in Java, Scala, or even Python, and these apps will run nearly ten times faster and 100 times faster than MapReduce apps.
Apache Spark works —
Apache Spark has a hierarchical master/slave architecture.
Based on the application code, Spark Driver generates the SparkContext, which works with the cluster manager—Spark’s Standalone Cluster Manager or other cluster managers like Hadoop YARN, Kubernetes, or Mesos— to distribute and monitor execution across the nodes.
Best Features of Apache Spark —
Lighting-fast processing speed–
Big Data processing, enterprises want such frameworks that can process massive amounts of data at high speed. As we mentioned earlier, Spark apps can run up to 100x faster in memory and 10x faster on disk in Hadoop clusters.
It relies on Resilient Distributed Dataset that allows Spark to transparently store data.This helps to reduce most of the disc read and write time during data processing.
Ease of use –
Spark allows you to write scalable applications in Java, Scala, Python, and R. So, developers get the scope to create and run Spark applications in their preferred programming languages. Moreover, Spark is equipped with a built-in set of over 80 high-level operators. You can use Spark interactively to query data from Scala, Python, R, and SQL shells.
It offers support for sophisticated analytics –
Spark supports SQL queries, streaming data, and advanced analytics, including ML and graph algorithms. It comes with a powerful stack of libraries such as SQL & DataFrames and MLlib (for ML), GraphX, and Spark Streaming.
Active and expanding community —
Developers from over 300 companies have contributed to design and build Apache Spark.
Naturally, Spark is backed by an active community of developers who work to improve its features and performance continually. To reach out to the Spark community, you can make use of mailing lists for any queries, and you can also attend Spark meetup groups and conferences.
Users of Spark —
Yahoo uses Spark for two of its projects, one for personalizing news pages for visitors and the other for running analytics for advertising. To customize news pages, Yahoo makes use of advanced ML algorithms running on Spark to understand the interests, preferences, and needs of individual users .
Uber uses Spark Streaming in combination with Kafka and HDFS to ETL (extract, transform,vast amounts of real-time data of discrete events into structured and usable data for further analysis. This data helps Uber to devise improved solutions for the customers.
As a video streaming company, Conviva obtains an average of over 4 million video feeds each month, which leads to massive customer churn. Conviva uses Spark Streaming to learn network conditions in real-time and to optimize its video traffic accordingly. This allows Conviva to provide a consistent and high-quality viewing experience to the users.
