Snowflake Certification Practice Test

True or False: The warehousing cache stores the results of executed queries for 24 hours.

1. True

2. False

3. N/A

4. Not applicable

The correct answer is: False

The assertion that the warehousing cache stores the results of executed queries for 24 hours is false. In Snowflake, the caching system does not specifically guarantee a fixed retention period of 24 hours for query results. Instead, the warehouse cache, which is part of Snowflake's architecture, stores query results for a shorter, undefined time period and is focused on improving the performance of subsequent queries that access the same data. Caching mechanisms can be influenced by various factors such as the resources of the virtual warehouse and the nature of data being queried. When data is modified or when the virtual warehouse is resized or suspended, this can lead to cache invalidation. Thus, while caching does accelerate performance by allowing the reuse of the results of recent queries, it does not necessarily adhere to a 24-hour timeframe for storage. This characteristic of dynamic caching is crucial for users to understand, especially when considering the performance and efficiency of their database operations.
