Field Details

LEGACY_REVISION

public static final String LEGACY_REVISION

Value written to the revision column of a saga inserted by this module, marking the row as one created here rather than by Axon Framework 4:

 SELECT sagaId FROM SagaEntry WHERE revision = 'axon-legacy'
 

Written on insert only. An update leaves the column alone, so a value written by Axon Framework 4 survives.
