Kenneth Knowles updated BEAM-1507:
----------------------------------
Labels: newbie starter triaged (was: newbie starter)
> java DataflowRunner should warn if the stagingLocation has a TTL
> ----------------------------------------------------------------
>
> Key: BEAM-1507
> URL: https://issues.apache.org/jira/browse/BEAM-1507
> Project: Beam
> Issue Type: Improvement
> Components: runner-dataflow
> Reporter: Daniel Halperin
> Priority: Minor
> Labels: newbie, starter, triaged
>
> 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.
