> Issue Type: Improvement
> Components: sdk-py

> We have seen a few customers run into a hard-to-track-down bug where the staging bucket has a TTL, but files get TTL-deleted when they are still needed.
> This might be because of:
> 1. Long lived batch jobs / streaming jobs can reference staged files arbitrarily later and will fail in bad ways if they have been deleted.
> 2. Some customers even hit issues where the "check file already exists" succeeds when starting a job, but then the file is TTL-deleted before the job actually starts. (This sounds crazy, but may happen if TTL is 7 days and jobs run every 7 days, for example. Race condition.)
> I'm hoping it's not hard to check that files would have TTLs and warn if so.
