transient property
A transient property is a property that is not persisted to the database. Transient properties can have non-null values on the clipboard, but when a clipboard page containing transient properties is saved to the PegaRULES database, the values are removed from the Storage Stream column. Similarly, when an instance containing a transient property is retrieved from the database and opened on the clipboard, the transient properties have no initial values on the clipboard.
