🧩 Handling Semi-structured Data in Snowflake | VARIANT, JSON & Parquet Explained
Welcome back to Snowflake Based Learning — where we simplify Snowflake concepts step by step! ❄️
In this video, we explore how Snowflake handles semi-structured data using the powerful VARIANT data type.
You’ll learn how to store, parse, and query JSON and Parquet files, including how to extract values from nested JSON fields.
If you're working with APIs, event data, logs, or modern data pipelines — this tutorial is essential.
🧠 What You’ll Learn:
✅ What semi-structured data means
✅ Understanding the VARIANT data type
✅ Loading JSON & Parquet into Snowflake
✅ Querying nested JSON fields
✅ Using dot notation & path expressions
✅ Flattening arrays with FLATTEN()
✅ Real-world examples & best practices
🧰 Tools & Concepts Used:
Snowflake Web Console
VARIANT columns
JSON & Parquet files
COPY INTO command
FLATTEN() function
🪄 Why This Matters:
Modern data is rarely perfectly structured.
Snowflake’s VARIANT support lets you:
⚡ Query JSON without complex preprocessing
📦 Store flexible schemas
🚀 Build scalable pipelines
🧩 Work with nested & hierarchical data easily
