public Duration getDuplicationDetectionHistoryTimeWindow()

Returns:

The duration of duplicate detection history that is maintained by the service. The default value is 1 minute.

getEntityStatus

public EntityStatus getEntityStatus()

Gets the status of the entity. When an entity is disabled, that entity cannot send or receive messages.

Returns:

The current status of the topic (Enabled / Disabled). The default value is Enabled.

getMaxSizeInMB

public long getMaxSizeInMB()

Returns:

the maximum size of the topic in megabytes, which is the size of memory allocated for the topic. Default value is 1024.

getPath

public String getPath()

Returns:

the path of the topic.

getUserMetadata
