Properties

hashCode → int

The hash code for this object.

no setter, inherited

healthy → bool

Whether the replica is healthy.

final

index → int

Member index within the database. Read role for which member accepts writes: a failover moves the primary without renumbering the indexes.

final

lagSeconds → double?

Replication lag in seconds (null for primary). Also null against replicating: true, for a member that is streaming but whose engine printed no numeric lag.

final

replicating → bool?

Whether the engine reports this member's replication stream as up. Null when no reading was taken: a primary has no stream to report, and a member that is not healthy, or whose probe did not answer, has none yet. healthy is a reachability probe of the member itself and says nothing about replication, so a healthy member may still not be replicating.

final

role → String

Member role. Possible values: primary (accepts reads and writes), replica (read-only follower), unknown (placement not established; reported while a transition is moving or restarting the topology, so no member can be named the write target).

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toMap() → Map<String, dynamic>

override

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
