	FileStreamSendRate	Gets the rate at which the files are sent to the secondary replica.
	IsFailoverReady	Gets or sets a value that indicates whether the database is marked synchronized in the cluster.
	IsJoined	Gets or sets a value that indicates whether the availability database has a physical replica on the server instance.
	IsLocal	Gets or sets a value that indicates whether the database is local to the instance.
	IsSuspended	Gets a value that indicates whether the state of the database replica is suspended.
	LastCommitLSN	Gets the LSN of the last commit record.

	LogSendQueueSize	Gets the amount of log records in the log files of the primary database that has not been sent to the secondary replica.
	LogSendRate	Gets the rate at which log records are being sent to the secondary replica.
	Parent	Gets the AvailabilityGroup object that is the parent of the DatabaseReplicaState object.
	Properties	Gets a collection of Property objects that represent the object properties. (Inherited from SqlSmoObject.)

	ReplicaAvailabilityMode	Gets the availability mode of the availability replica.
	ReplicaRole	Gets the role of the availability replica.
	State	Gets the state of the referenced object. (Inherited from SmoObjectBase.)
	SuspendReason	Gets the reason for a database replica to be in suspended state.
	SynchronizationPerformance	Gets the performance of the synchronization for the database.
	SynchronizationState	Gets the state of the availability database synchronization.
	TruncationLSN	Gets the log truncation value, which may be higher than the local truncation LSN if local log truncation is blocked.
