A Snowflake external table is a table that references data stored (be it JSON or CSV) outside of Snowflake in a external location, such as an S3 bucket or Azure Blob storage. These tables allow for easy access to external data (JSON) without the need to load it into Snowflake storage. External tables can be queried and joined with other Snowflake tables, just like a regular table. They also have the added benefits of being cost effective and allowing for dynamic data access without the need for manual data loads.
This "How To Create Snowflake External Table With JSON Data" tutorial Chapter-04 covers stage creation to file formate creation to external table DDL statements besides many important facts about JSON data handling in snowflake using external tables.
Once you finish this chapter-04, you will be able to answer the following questions:
1. How to use external stages to onboard JSON data using external tables?
2. How external table DDL looks like for JSON data?
3. How query performance works with JSON data and external table?
4. What is needed to keep external table fresh when new JSON data arrives?
5. Does external table need notification services to get the fresh data?
6. How to query external stage which has JSON data stored?
7. Can external table be created on the top of internal stage?
