Topic 2 Question 6
Which of these statements about BigQuery caching is true?
By default, a query's results are not cached.
BigQuery caches query results for 48 hours.
Query results are cached even if you specify a destination table.
There is no charge for a query that retrieves its results from cache.
解説
When query results are retrieved from a cached results table, you are not charged for the query. BigQuery caches query results for 24 hours, not 48 hours. Query results are not cached if you specify a destination table. A query's results are always cached except under certain conditions, such as if you specify a destination table.
