Learn the Databricks certified associate developer for Apache Spark 3 course material, exam prerequisites, and certification paths from a credentialed instructor who cracked the Apache Spark 3.2 exam.
Review the Databricks exam structure, certification process, prerequisites, and pricing, and outline Spark architecture, DataFrame API tasks, and related topics for the associate developer exam.
Explore how S3 data arrives in Databricks. Create and manage a data frame partition, and upload the complete data set within a Databricks workflow.
Learn how to create an azure databricks workspace via the azure portal, including creating a resource group, configuring secure cluster connectivity, and launching the databricks portal.
Navigate the Azure Databricks workspace, mastering control plane and data plane roles, notebooks, and permissions. Configure clusters, job runs, repos, Unity Catalog, and runtimes to optimize workflows.
Sign up for the Databricks community edition, create a workspace and notebooks, import and export notebooks, and preview the architecture of Databricks and Spark, including cluster and driver roles.
Create a Databricks compute cluster in the community edition, attach a notebook, and run your first code with python, aws cli, and pandas.
Explore Spark architecture, including driver and executors, cluster manager, in-memory processing, data partitions, stages, and shuffles, and contrast it with Hadoop's disk-based approach.
Explore Spark architecture, including the driver, executors, and cluster managers, and learn how jobs split into stages and tasks, with immutable RDDs and dataframe transformations.
Explore RDD, DataFrame, and DataSet APIs, compare performance, language support, and processing models, and master concepts like lazy evaluation, fault tolerance, and Dag Scheduler for scalable data analytics.
Learn the difference between transformations and actions in Spark, understand lazy evaluation until an action runs, and review common actions (collect, show, count) and transformations (map, filter).
Explore creating dataframes with the Spark dataframe API in Databricks, from sign-up and cluster setup to using show, display, take, head, collect, and SQL queries via temp views.
Master selecting data in spark dataframes using API methods, expressions, and sql, then rename and manipulate columns while inspecting schemas and previewing results.
Master renaming DataFrame columns in Spark by using withColumn and withColumnRenamed, understand when new columns are created versus overwriting old names, and apply aliasing to rename multiple columns efficiently.
Learn basic column manipulation in spark, including creating a data frame with a schema and using withColumn, concat, upper, lower, initcap, and length to transform columns.
Learn basic column manipulation in Spark by selecting employee id and first name, importing explode and split, and using explode on a comma-separated phone numbers column to create multiple rows.
Explore drop APIs in Spark dataframes: drop columns, drop duplicates, and drop nulls using drop, drop duplicates, and drop any versus all, including subset-based and list-based column selection.
