Enum Class DirtyCheck

java.lang.Object

java.lang.Enum<DirtyCheck>

st.orm.DirtyCheck

All Implemented Interfaces:

Serializable, Comparable<DirtyCheck>, Constable

public enum DirtyCheck
extends Enum<DirtyCheck>

Defines how dirty checking is performed for an entity.

This enum controls how field changes are detected when dynamic updates are enabled.

• DEFAULT – Use the configured dirty check strategy as defined by the storm.update.dirty_check property (see StormConfig).
• INSTANCE – Fields are considered dirty as soon as their reference changes. This mode is fast and avoids potentially expensive value comparisons.
• VALUE – Fields are compared using semantic equality. A field is only considered dirty when its value has changed.
