Question on caching
Say I have 1 workflow that has 1000 scatter chunks, with caching pointing to a mysql database. The workflow failed when 100 scatter tasks were complete, but a further 400 was still running at the time of failure (an LSF system) and were able to successfully complete. Will the 400 tasks that finish after the main cromwell process failed still be recorded in the cache?
