Meet Redshift, a robust columnar data warehouse. We'll explore how columnar and typical data warehouses differ, what makes Redshift unique, how it fits into the AWS and data warehouse ecosystems, and what data types it supports.

Redshift, a data warehouse

Let's learn about some nuances with Redshift SQL syntax, a close cousin of PostgreSQL's syntax. We compare CTEs and subqueries before moving into mastering date and time, exploring window queries, and wrapping up learning how transactions affect some functions. 

Using CTEs with Redshift

Filtering with CTEs

CTE Concepts

Date and time functions

Truncating dates

Extracting date parts

Find future dates

Windowing in Redshift

Windowing to the max

Comparing periods with lag

Transactions

Transaction structure

Consistent dates in a transaction

SQL on Redshift

We'll explore how to create tables, the impact DISTKEY and SORTKEYs have on performance, external schemas/tables with Spectrum and wrap up with handling semi-structured data like JSON with Redshift.

Tables in Redshift

Creating a table and setting properties

Learning more about a table's columns

External Schemas, File, and Table Formats

Table formats vs file types

Identifying internal and external schemas

Finding the internal or external tables

Semistructured data

Extracting top level JSON keys

Extracting nested JSON keys

Tables and working with semi-structured data

It is time to peak into the world of writing optimized queries and tools available to help optimize. Then, we turn our attention to Redshift security capabilities and how they can impact query output.
