When does a cached Big Query job expire?

Question

I am currently using bigquery and whenever a query is run, the job is cached in memory and subsequent pages can be fetched from the cached table. So, is there a fixed expiration date for the cached tables? What factors does the job data persistence depend on? I am trying to see if the job still exists if I come back after a week or a month.

Answer 1

Directly from the docs (if you Google "App Engine BigQuery Caching") :

Results are cached for approximately 24 hours and cache lifetimes are extended when a query returns a cached result.

So basically, as long as you get your cached result once every 24 hours, cache should stay indefinitely.
