| # Required since we cannot guarantee instances are always terminated. | |
| # Also a failsafe against a dev writing a workflow that does not terminate build instances. | |
| # Though the average Airbyte build runtime as of this commit is ~20 mins, connector builds | |
| # can take up to 3 hours. Set this to 3 hours to include these longer runs. | |
