Caching in Snowflake: The Secret Sauce for High Performance

Snowflake’s architecture is designed to provide unparalleled performance, scalability, and ease of use for data workloads. One of the key factors behind Snowflake’s efficiency is its sophisticated caching mechanisms. By leveraging caching, Snowflake minimizes query execution time and optimizes resource usage. Let’s dive into the types of caching in Snowflake and how they work.

1. Result Cache (Query Results Stored in the Cloud Services Layer)

The Result Cache is a Snowflake feature that stores the results of executed queries. If the same query is executed again, Snowflake can retrieve the results from the cache instead of re-executing the query. This leads to lightning-fast response times for repetitive queries.

Key Characteristics:

• Fast Results: Query results are persisted in the cache, enabling quick retrieval.
• Avoids Re-execution: By skipping the actual computation, Snowflake reduces processing time and resources.
• USE_CACHED_RESULT Parameter: This parameter determines whether Snowflake will use the cached results for a query. Default: Enabled, To disable: Use USE_CACHED_RESULT = FALSE.
• 24-Hour Purge: If the query is not re-used…
