Nosql Column-oriented database tutorial

Does anybody have any good links to code snippets on how to create a nosql Column-oriented database as well as crud code? I’m new and this would help me get started.

I found a link for " Compress data with columnar tables in Azure Cosmos DB for PostgreSQL" but I’m getting an error when I try to post it here.

CREATE TABLE contestant (
handle TEXT,
birthdate DATE,
rating INT,
percentile FLOAT,
country CHAR(3),
achievements TEXT
) USING columnar;

Incorrect syntax near ‘USING’.

This is on Windows 10 SQL Server

I need to use Azure Cosmos DB

Try the Essentials course on ScyllaDB University. It includes some hands-on labs where you can create a Table and do some basic queries.
