-----------------------------------
Summary: Transaction isolation on DB stores is too strict
Key: AURORA-1386
URL: https://issues.apache.org/jira/browse/AURORA-1386
Project: Aurora
Issue Type: Bug
Components: Scheduler
Reporter: Bill Farner
Assignee: Bill Farner
Priority: Critical
The transaction isolation used in the scheduler's DB-based storage is too
strict. This results in inconsistent data when work in a transaction forks
asynchronous work on a different thread, which is implicitly done for messages
on the event bus. In cases like {{TaskThrottler}} which has some preconditions
around expected state, we encounter exceptions related to the ancestor state
not yet being shown as terminated as we try to calculate the reschedule delay.
