Databricks is a cloud-based lakehouse platform built on Apache Spark for processing big data, combining data lake flexibility with data warehouse ACID transactions across multi-cloud providers.
Explore how the lakehouse blends data lake flexibility with data warehouse structure for analytics and machine learning; Databricks uses multi-cloud control plane and data plane with Spark and Delta Lake.
Spark on Databricks uses a distributed in-memory compute engine to process big data, enabling batch and streaming workloads, with Dbfs storage and support for Scala, Python, PySpark, Java, and R.
Create an Azure account by signing up with a Microsoft account, validating with captcha and phone verification, entering profile and payment details, and accessing the Azure portal.
Explore the Databricks workspace environment, organize notebooks with folders, manage data in the catalog, and leverage workflows, compute infrastructure, and SQL tools for data engineering and machine learning.
Learn to create compute infrastructure in Databricks, selecting all‑purpose or job compute, configuring multi‑node or single‑node clusters, autoscaling, runtime versions, and idle termination settings.
Create and manage a Databricks notebook, set Python as default (with SQL, Scala, or R), add and run code on a demo cluster, and use markdown and cells.
Learn how to import notebooks into a Databricks workspace, define Spark schemas, create and union data frames, apply filters, and run PySpark with SQL and language magic commands.
Explore the lakehouse concept by integrating data lake storage with data warehouse features, using delta tables and parquet formats to enable tabular analysis of structured and unstructured data.
Compare database, data warehouse, and data lake concepts. Discover how Delta Lake enables Lake House architectures with managed and external tables.
Explore delta lake, a lakehouse open source storage format that adds reliability to data lakes on Azure Databricks, using delta tables, parquet files, and log files for versioned, consistent reads.
Create a Delta Lake table in a Hive metastore catalog, describe details, and insert data to generate parquet files and log files for Delta Lake storage.
Insert data into Delta Lake, observe data and log file growth across Parquet files, and perform updates that create new Parquet and log files while tracking changes with describe history.
Explore Delta Lake additional configurations by copying data from an existing table, creating new tables, using where filters, derived columns, partition by, and inspecting metadata with describe details.
Delta Lake time travel lets you access past data by timestamp or version and restore a table to a prior version, while also covering vacuum and optimization features.
Explore Delta Lake restore options and versioning in Azure Databricks basics. Learn to restore to a prior version using asof or timestamp, view history, and verify data after restoration.
Learn how to use Delta Lake's optimize operation to reduce many small files into larger ones, preserving old files, and boost query performance with z-order by id for faster where-clauses.
Discover how Hive metastore stores database metadata in Azure Databricks, with default and custom databases, and how data saves under dbfs user hive warehouse.
Explore managed vs external tables in Databricks, where managed tables store data and metadata and external tables retain only metadata, and learn how drops affect each.
Discover how the Delta Lake vacuum command deletes seven-day-old historical files to reduce storage costs, with options to adjust retention in Databricks.
Apply the Delta Lake optimize command to compact small files into larger ones, boosting query performance by reducing io operations; use z order by to optimize column-filtered queries.
Learn how the vacuum command in Delta Lake removes old data and cleans up files beyond the retention period, with a default seven-day retention and time-travel risks.
Delta Lake stores data in Parquet format and uses a JSON transaction log, enabling time travel to access older versions by version as of or timestamp as of.
Learn how to grant and understand delta table permissions in Azure Databricks using SQL statements like modify, select, insert, delete, alter, drop, and truncate, covering data access and schema changes.
