This video provides a practical guide to using Apache Spark, focusing on running Spark locally with Docker and Databricks Community Edition. Dmitry Anoshin demonstrates how to interact with the Spark UI to understand job execution, analyze performance metrics like data input size and resource usage, and troubleshoot potential issues. The tutorial covers core Spark concepts like transformations, actions, and data skew, using example code and visualizations from the Spark UI to explain how jobs are divided into stages and tasks. While briefly touching on optimization techniques, the video primarily emphasizes the importance of the Spark UI for monitoring and understanding Spark job execution, especially for those new to the platform.

What is Surfalytics?

Inspired by West Coast surfing spots 🏖️ and Pacific Ocean vibes 🌊. Created to help you start a new career in the data analytics space, and develop data engineering and analytics skills through coaching. It will teach you not just dry skills, but will keep your focus on delivering significant value to businesses in the analytics realm as well as help to get fair compensation 💰 for the work you’re passionate about ❤️‍🔥.

The goal of Surfalytics is to assist you in achieving one of the following:

🏄‍♂️ Land your first job in the data industry with literally zero experience. I have accomplished this many times across the globe.

🏄 Advance from a middle-level role to a senior position (as an Analyst or Engineer).

🏄‍♀️ Transition from a non-technical Analyst role to a technical Engineer role.

Moreover, we will focus on creating a highly competitive CV and securing top job offers. We will not consider any lowball offers, focusing only on top-tier companies and well-paid opportunities.

Finally, Surfalytics is a results-driven community with a very narrow focus, resulting in a high return on investment (ROI). Here, ‘investment’ does not mean money but your time. I am literally fighting for your attention to encourage you to study and work hard, instead of watching Netflix or playing video games.

This is the best YouTube channel for Data Analytics and Engineering. You will patch up a lack of knowledge and get new experience and tips to build a Data Analyst roadmap or Data Engineer roadmap for yourself.
