Caching

If a query is cached, you won't be charged

To retrieve data from stored cache, the query should be the exact replica of the original query.

It must have a size <10Gb

Not cached:

• When the destination table is spcidied to store results in in query
• If tables/views have changed
• In tables with streaming ingestion
• If using non-deterministic functions like timestamp(), now(), current_user()
• Using external data sources like BigTable or CloudStorage
