In the world of big data processing, efficient and scalable file systems play a crucial role. One such file system that has gained popularity in the Apache Spark ecosystem is DBFS, which stands for Databricks File System. In this blog post, we’ll explore into what DBFS is, how it works, and provide examples to illustrate […]

DataFrame is a key abstraction in Spark which represents structured data and allows for easy manipulation and analysis. In this blog post, we’ll explore the various basic DataFrame methods available in Spark and how they can be used for data processing tasks using examples. Dataset: There are many DataFrame methods which are subclassified into Transformation […]

What is Databricks? Databricks is a cloud-based data processing and data warehousing platform that has gained immense popularity in recent years. It was developed by the creators of Apache Spark, an open-source big data processing framework. Databricks provides a unified analytics platform that allows businesses to process and analyze large volumes of data efficiently and […]

Apache Spark is a powerful open-source distributed computing system widely used for big data processing and analytics. When working with structured data, one common challenge is dealing with parsing errors—malformed or corrupted records that can hinder data processing. Spark provides flexibility in handling these issues through parser modes, allowing users to choose the behavior that […]

Spark Persistence is an optimization technique, which saves the results of RDD evaluation. Spark provides a convenient method for working with datasets by storing them in memory throughout various operations. When you persist a dataset, Spark stores the data on disk or in memory, or a combination of the two, so that it can be […]

In Spark with Scala, creating DataFrames is fundamental for data manipulation and analysis. There are several approaches for creating DataFrames, each offering its unique advantages. You can create DataFrames from various data sources like CSV, JSON, or even from existing RDDs (Resilient Distributed Datasets). In this blog we will see some approaches towards creating dataframe […]

Reading Azure EventHub Data into DataFrame using Python in Databricks Azure EventHubs offer a powerful service for processing large amounts of data. In this guide, we’ll explore how to efficiently read data from Azure EventHub and convert it into a DataFrame using Python in Databricks. This walkthrough simplifies the interaction between Azure EventHubs and the […]

In Apache Spark, efficient data management is essential for maximizing performance in distributed computing. Partitioning, repartitioning, and coalescing actively govern how data organizes and distributes across the cluster. Partitioning involves dividing datasets into smaller chunks, enabling parallel processing and optimizing operations. Repartitioning allows for the redistribution of data across partitions, adjusting the balance for more […]

A comprehensive understanding of Spark’s transformation and action is crucial for efficient Spark code. This blog provides a glimpse on the fundamental aspects of Spark.  Before we deep dive into Spark’s transformation and action, let us see a glance of RDD and Dataframe.  Resilient Distributed Dataset (RDD): Usually, Spark tasks operate on RDDs, which is […]
