This course is the result of my over 4 years of experience working with Snowflake. Snowflake is a fantastic tool to handle huge volumes of data. You can load, query and export, and run transactional queries on TB's and PB's of data easily.

You don't have to worry about infrastructure setup, security, performance, tuning, Garbage collection, node failures etc etc...

if you have already worked with Spark with EMR or with Data bricks you will be amazed by snowflake performance and simplicity.

But there is a catch, if you are not fully aware of how things works in snowflake, you will easily loose control and end up writing costly queries and end up using many of snowflake features wrongly.

I mentioned costly queries because snowflake is build for performance.

Costly queries and wrong design decisions in snowflake will sky rocket your snowflake bill. I have made lot of such mistakes and learned from those mistakes.

This course is an effort to walk you through such experiences so that you don't end up doing same mistakes which i did!!!

Few things can only be learned by experience you can't find them in documentations this course will expose such details to you.


Hope you join me in this journey...................


The course is broadly divided into 3 modules,

Module#1

Lectures------------>: 38

Real time Demos----->: 11

Assignments--------->: 10

Quiz------------------>: 6


  • This module will concretize snowflake fundamental concepts and architecture.

  • By the end of this module you will be having very strong foundation about snowflake.

Module#2

Lectures------------>: 46

Real time Demos----->: 31

Assignments--------->: 14

Quiz------------------>: 2


  • In this module i will walk you through, different techniques and options to load and unload data

    in snowflake.

  • By the end of this module, you will be having great confidence in using COPY command and

    different data processing objects in snowflake.

Module#3

Lectures------------>: 45

Real time Demos----->: 35

Quiz------------------>: 3


  • In this module, we closely evaluate important features of snowflake.

  • This module helps you to understand, how each feature works under the hood.

  • Through this knowledge you will be in a better position to decide, when to use the feature and when not to use the snowflake features.
