What is Spark?
Apache Spark is an open-source tool. This framework can run in a standalone mode or on a cloud or cluster manager such as Apache Mesos, and other platforms. It is designed for fast performance and uses RAM for caching and processing data.
Spark was introduced by Apache Software Foundation for speeding up the Hadoop computational computing software process.
Who is Founder of Spark?
Matei Zaharia is a Romanian-Canadian computer scientist, educator and the creator of Apache Spark
What are Spark big data workloads?
. This includes MapReduce-like batch processing, as well as real-time stream processing, machine learning, graph computation, and interactive queries. With easy to use high-level APIs, Spark can integrate with many different libraries, including PyTorch and TensorFlow. To learn the difference between these two libraries, check out our article on PyTorch vs. TensorFlow.
What is Spark used for?
Based on in-memory caching, and optimized query execution for fast analytic queries against data of any size.It very popular now a days
What are language Spark support?
There are five main components of Apache Spark:
Apache Spark Core. The basis of the whole project. Spark Core is responsible for necessary functions such as scheduling, task dispatching, input and output operations, fault recovery, etc. Other functionalities are built on top of it.
Spark Streaming. This component enables the processing of live data streams. Data can originate from many different sources, including Kafka, Kinesis, Flume, etc.
Spark SQL. Spark uses this component to gather information about the structured data and how the data is processed.
Machine Learning Library (MLlib). This library consists of many machine learning algorithms. MLlib’s goal is scalability and making machine learning more accessible.
Are Spark and Hadoop the same?
As against a common belief, Spark is not a modified version of Hadoop and is not, really, dependent on Hadoop because it has its own cluster management. Hadoop is just one of the ways to implement Spark.
Spark uses Hadoop in two ways – one is storage and second is processing. Since Spark has its own cluster management computation, it uses Hadoop for storage purpose only.
