Class IgniteClusterAsyncImpl

    • Constructor Detail

      • IgniteClusterAsyncImpl

        public IgniteClusterAsyncImpl()
        Required by Externalizable.

      • IgniteClusterAsyncImpl

        public IgniteClusterAsyncImpl​(IgniteClusterImpl cluster)
        Parameters:
        cluster - Cluster.

    • Method Detail

      • forLocal

        public ClusterGroup forLocal()
        Gets a cluster group consisting from the local node.
        Specified by:
        forLocal in interface IgniteCluster
        Returns:
        Cluster group consisting from the local node.

      • nodeLocalMap

        public <K,​V> ConcurrentMap<K,​V> nodeLocalMap()
        Gets node-local storage instance.

        Node-local values are similar to thread locals in a way that these values are not distributed and kept only on local node (similar like thread local values are attached to the current thread only). Node-local values are used primarily by closures executed from the remote nodes to keep intermediate state on the local node between executions.

        There's only one instance of node local storage per local node. Node local storage is based on ConcurrentMap and is safe for multi-threaded access.

        Specified by:
        nodeLocalMap in interface IgniteCluster
        Type Parameters:
        K - Type of keys in the node local map.
        V - Type of mapped values in the node local map.
        Returns:
        Node local storage instance for the local node.

      • pingNode

        public boolean pingNode​(UUID nodeId)
        Pings a remote node.

        Discovery SPIs usually have some latency in discovering failed nodes. Hence, communication to remote nodes may fail at times if an attempt was made to establish communication with a failed node. This method can be used to check if communication has failed due to node failure or due to some other reason.

        Specified by:
        pingNode in interface IgniteCluster
        Parameters:
        nodeId - ID of a node to ping.
        Returns:
        true if node for a given ID is alive, false otherwise.
        See Also:
        DiscoverySpi

      • topologyVersion

        public long topologyVersion()
        Gets current topology version. In case of TCP discovery (see TcpDiscoverySpi) topology versions are sequential - they start from '1' and get incremented every time whenever a node joins or leaves. For other discovery SPIs topology versions may not be (and likely are not) sequential.
        Specified by:
        topologyVersion in interface IgniteCluster
        Returns:
        Current topology version.

      • topology

        @Nullable
public @Nullable Collection<ClusterNode> topology​(long topVer)
        Gets a topology by version. Returns null if topology history storage doesn't contain specified topology version (history currently keeps last 1000 snapshots).
        Specified by:
        topology in interface IgniteCluster
        Parameters:
        topVer - Topology version.
        Returns:
        Collection of grid nodes which represented by specified topology version, if it is present in history storage, null otherwise.

      • startNodes

        public Collection<ClusterStartNodeResult> startNodes​(File file,
                                                     boolean restart,
                                                     int timeout,
                                                     int maxConn)
        Starts one or more nodes on remote host(s).

        This method takes INI file which defines all startup parameters. It can contain one or more sections, each for a host or for range of hosts (note that they must have different names) and a special 'defaults' section with default values. They are applied to undefined parameters in host's sections.

        Returned result is collection of tuples. Each tuple corresponds to one node start attempt and contains hostname, success flag and error message if attempt was not successful. Note that successful attempt doesn't mean that node was actually started and joined topology. For large topologies (> 100s nodes) it can take over 10 minutes for all nodes to start. See individual node logs for details.

        Supports asynchronous execution (see IgniteAsyncSupport).

        Specified by:
        startNodes in interface IgniteCluster
        Parameters:
        file - Configuration file.
        restart - Whether to stop existing nodes. If true, all existing nodes on the host will be stopped before starting new ones. If false, nodes will be started only if there are less nodes on the host than expected.
        timeout - Connection timeout.
        maxConn - Number of parallel SSH connections to one host.
        Returns:
        Collection of start node results, each containing host name, result (success or failure) and error message (if any).

      • enableWal

        public boolean enableWal​(String cacheName)
                  throws IgniteException
        Enables write-ahead logging for specified cache. Restoring crash-recovery guarantees of a previous call to IgniteCluster.disableWal(String).

        Internally this method will wait for all current cache operations to finish and prevent new cache operations from being executed. Then checkpoint is initiated to flush all data to disk. Control is returned to the callee when all data is persisted to disk.

        WAL state can be changed only for persistent caches.

        NOTE: Currently, this method should only be called on a stable topology when no nodes are leaving or joining cluster, and all baseline nodes are present. Cache may be stuck in inconsistent state due to violation of these conditions. It is advised to destroy such cache.

        Specified by:
        enableWal in interface IgniteCluster
        Parameters:
        cacheName - Cache name.
        Returns:
        Whether WAL enabled by this call.
        Throws:
        IgniteException - If error occurs.
        See Also:
        IgniteCluster.disableWal(String), IgniteCluster.isWalEnabled(String)

      • disableWal

        public boolean disableWal​(String cacheName)
                   throws IgniteException
        Disables write-ahead logging for specified cache. When WAL is disabled, changes are not logged to disk. This significantly improves cache update speed. The drawback is absence of local crash-recovery guarantees. If node is crashed, local content of WAL-disabled cache will be cleared on restart to avoid data corruption.

        Internally this method will wait for all current cache operations to finish and prevent new cache operations from being executed. Then checkpoint is initiated to flush all data to disk. Control is returned to the callee when all dirty pages are prepared for checkpoint, but not necessarily flushed to disk.

        WAL state can be changed only for persistent caches.

        NOTE: Currently, this method should only be called on a stable topology when no nodes are leaving or joining cluster, and all baseline nodes are present. Cache may be stuck in inconsistent state due to violation of these conditions. It is advised to destroy such cache.

        Specified by:
        disableWal in interface IgniteCluster
        Parameters:
        cacheName - Cache name.
        Returns:
        Whether WAL disabled by this call.
        Throws:
        IgniteException - If error occurs.
        See Also:
        IgniteCluster.enableWal(String), IgniteCluster.isWalEnabled(String)

      • id

        public UUID id()
        Cluster ID is a unique identifier automatically generated when cluster starts up for the very first time.
