title: Cache Data in Google Cloudbuild
body: <p>I would like to use Google Cloudbuild to run integration tests. Currently, my tests take 30 minutes to run. The main bottleneck is that the tests query lots of data from external sources. I don't mind reusing the same data every time I run the tests. Is there a way for me to cache that data somewhere local to Cloudbuild so that it loads much faster?</p>
