📝 Questions & Answers:

Q1: What is result set caching vs warehouse caching?
A1: Result set cache returns previous query results instantly when identical; warehouse cache stores data pages to speed execution; both reduce compute. Example: Result cache is handing out an existing printed report; warehouse cache is having the frequently used books already on the reading-room table.

Q2: What are UDFs and stored procedures in Snowflake?
A2: UDFs (SQL/JavaScript) and stored procedures encapsulate reusable logic and can be used in queries or tasks. Example: Like creating a small helper routine that formats or computes values you use often.

Q3: What is zero-copy cloning for time/space efficiency?
A3: Zero-copy cloning makes cheap logical copies by sharing underlying storage until diverging writes occur, saving space and time. Example: Like making instant photocopies that don’t use extra paper until you edit a page.
