Class PerNodeLocalQueueManager

java.lang.Object

com.atlassian.bamboo.cluster.PerNodeLocalQueueManager

public class PerNodeLocalQueueManager
extends Object

Stores all active queues PerNodeLocalQueue and manages the queue dispatchers PerNodeLocalQueueDispatcherImpl

We are storing events only for the live nodes (the nodes which last successful heartbeat was within BambooClusterSettings.CLUSTER_HEARTBEAT_ALIVE_TIMEOUT_IN_SECONDS). If any of the live nodes disappears, we are removing its queue, dispatcher and events, as a result these events won't be ever sent to the node. To make it work, we need to force the node that became NOT live to not ever become operational once again without explicit restart - NodeAliveWatchdogJob makes sure this requirement is met. If the node was unresponsive but never became officially not alive (it came back within BambooClusterSettings.CLUSTER_HEARTBEAT_ALIVE_TIMEOUT_IN_SECONDS), we send all the buffered events once it comes back.

The events are sent in the asynchronous way, and no response is expected from the node. This manager should be used for events propagation only.

9.5.0
