These 7 Tools Turn Apache Spark Into Fire
Spark has gained momentum for Data Processing requirements. In no time, it has become the popular choice for handling, managing, and churning data, leaving behind Hadoop's MapReduce Framework. Apache Spark has made Big Data processing simpler, more powerful, and more convenient. Spark is a bundle of components under a common umbrella and not just one single standalone technology. Each component in the framework gets regularly updated with new performance features. Here's a comprehensive introduction to all the pieces that make Apache Spark complete: · Spark Core – The heart of Apache Spark is Spark Core. It is responsible for scheduling and coordinating jobs and provides the basic abstraction for data called the Resilient Distributed Dataset (RDD). RDDs are responsible for two actionstransformations and actions. Transformations are the changes made in the data and actions are the computation of result on the basis of existing RDD. · Spark APIs – Spark is mainly written in Scala, and so the primary APIs for Spark have long been used for Scala as well. Apart from Scala, three more popular and widely used languages are also supported- Java, Python, and R. The Machine Learning support
in SparkR, however, is not that robust by comparison and only has a subset of algorithms currently available. · Spark SQL – Apache Spark has never misunderstood the importance of being able to run a SQL query against data. Through Spark SQL, queries can be performed on the data in Spark, including the ability to query through ODBC/JDBC connectors. UPDATE queries are not supported on Spark. · Spark Streaming – Apache Spark Streaming was said to be used only when there was no need of split-second latencies, or if there was not already an investment in any other Streaming solution, for an instance, Apache Storm. Spark 2.0 has promised a new structures streaming model which will enable Interactive Spark SQL queries on live data. · MLlib – Spark allows its users to run Machine Learning algorithms that are common today, on Spark data, making these analyses easier and accessible to Spark users. MLlib is expanding with each revision and has a long list of algorithms even today. However, there are some algorithms that aren't available yet, like anything related to Deep Learning. Third parties are pushing hard to fill this gap, like Yahoo can perform Deep Learning through CaffeOnSpark, that leverages the Caffe deep learning system through Apache Spark. · GraphX – Graph is required for the need to map relationships between millions of entities to define how they relate to one another. The GraphX API of Spark helps you perform Graph operations on data using Spark methodologies. GraphX also includes common data processing algorithms like PageRank and label propagation. One limitation that haunts the users of GraphX is that it works fine with the graphs that are static, meaning that the addition of new vertices leads to performance impairment. · SparkR – The R language is imperative for performing statistical and numerical analysis and other Machine Learning works. Spark added the support for R in June 2015 to match its support for Python and Scala. Spark allows for R developers to carry out many functions that they couldn't previously- like accessing datasets larger than the memory of a single machine, or running analyses in multiple threads or multiple machines simultaneously. Through SparkR, users can also make use of the MLlib module in Spark to create general linear models. With Spark's growing popularity in the Big Data and Machine Learning space, it is important for all businesses and organizations to get hands dirty with its applications. Big Data adoption reached 53 percent last year from 15 percent in 2015. Some early adopters of the Big Data technology include the telecom and finance sectors and the top use case of Big Data has come out to be Data Warehouse Optimization.
