# #region Alembic.MaintenanceEventAutoEnd [C:3] [TYPE Module] [SEMANTICS alembic,maintenance,auto-end,column]
|
|
# @ingroup Alembic
|
|
# @BRIEF Add maintenance_events.auto_end flag (opt-in automatic ending at end_time).
|
|
# @LAYER Database
|
|
# @RELATION DEPENDS_ON -> [Models.Maintenance.MaintenanceModels]
|
|
# @INVARIANT auto_end defaults to false — end_time stays informational unless the caller opts in.
|
|
# @RATIONALE end_time alone is used for idempotency and banner text; an explicit flag lets the
|
|
# scheduler end maintenance automatically only when the caller asks for it.
|
|
# @REJECTED Auto-ending on end_time presence alone was rejected — ETL tools may pass a window
|
|
# purely informational and would be surprised by an automatic end.
