Result Cache

Snowflake's cloud-services cache of query results, reused for identical queries for 24 hours (extendable to 31 days) if the underlying data has not changed.

Definition

Result cache hits don't require a running warehouse and consume no warehouse credits. Reuse requires a syntactically identical query, unchanged data, the necessary privileges and no nondeterministic functions such as CURRENT_TIMESTAMP. It can be disabled with USE_CACHED_RESULT = FALSE.

Exam tip

The result cache lives in the cloud services layer and survives warehouse suspension; the warehouse (local disk) cache does not.
