Specifies whether to use Google BigQuery's built-in query cache for eligible queries.

解説

Google BigQuery automatically caches the results of recent queries. By default, if a matching cached result exists and the underlying data has not changed, Google BigQuery returns the cached result instead of re-executing the query. This improves performance and reduces cost without returning stale data since the cache is invalidated automatically when the referenced tables are modified.

When this property is set to true, the 本製品 allows Google BigQuery to use cached results when available.

When set to false, the query is always executed directly against the current table data, bypassing the cache entirely.

Use this property to control whether cached results should be used for performance optimization. Disable caching for scenarios where full re-evaluation is necessary—such as benchmarking or auditing.
