Method Details

• ​

  getActiveHeadNodeUrl

  public URL getActiveHeadNodeUrl()

• ​

  getSystemProperties

  public Map<String,String> getSystemProperties()

• ​

  getWorkerRankUrls

  public List<URL> getWorkerRankUrls()

  Gets the URLs of the cluster’s worker ranks, indexed such that entry i is rank i + 1; the head rank is not included.

  A rank that has been removed from the cluster keeps its slot in this list, as null. That slot is load-bearing: the worker indices produced by the server’s shard routing table are rank numbers, so dropping it would shift every rank above the removed one and silently misroute sharded records. Code that walks this list must skip null entries rather than dereference them.

  Returns:

  the worker rank URLs, with a null at the slot of every removed rank

• ​

  getHostNames

  public Set<String> getHostNames()

• ​

  getHostManagerUrl

  public URL getHostManagerUrl()

• ​

  getIsPrimaryCluster

  @Deprecated(since=“7.2.2”, forRemoval=true) public boolean getIsPrimaryCluster()

  Deprecated, for removal: This API element is subject to removal in a future version.

• ​

  isMultiHeadAvailable

  public boolean isMultiHeadAvailable()

  Whether multi-head operations are available on this cluster from this client.

  Distinct from the disableAutoDiscovery option, which records what the user asked for and applies to the whole HA ring. This records what was actually observed for one cluster: a cluster whose worker addresses this client cannot reach is usable through its head node, and that loss of capability belongs to the cluster, not to the connection.

  Returns:

  whether multi-head is available on this cluster

• ​

  setMultiHeadAvailable

  public GPUdbBase.ClusterAddressInfo setMultiHeadAvailable(boolean value)

• ​

  getIsIntraClusterFailoverEnabled

  @Deprecated(since=“7.1.9”, forRemoval=true) public static boolean getIsIntraClusterFailoverEnabled()

  Deprecated, for removal: This API element is subject to removal in a future version.

  Get whether intra-cluster failover is enabled

• ​

  isPrimaryCluster

  public boolean isPrimaryCluster()

  Another getter for the primary cluster boolean flag for convenience.

• ​

  getHaStatus

  public String getHaStatus()

  Get the HA status (drained value) for this cluster.

  Returns:

  The HA status string (e.g., “drained”, “draining”, “not_drained”), or null if not set

• ​

  isIntraClusterFailoverEnabled

  @Deprecated(since=“7.1.9”, forRemoval=true) public static boolean isIntraClusterFailoverEnabled()

  Deprecated, for removal: This API element is subject to removal in a future version.

  Get whether intra-cluster failover is enabled

• ​

  setActiveHeadNodeUrl

  public GPUdbBase.ClusterAddressInfo setActiveHeadNodeUrl(URL value)

  Set the active head node URL. Return this object to be able to chain operations.

• ​

  setSystemProperties

  public GPUdbBase.ClusterAddressInfo setSystemProperties(Map<String,String> value)

  Set the system properties. Return this object to be able to chain operations.

• ​

  setHostManagerUrl

  public GPUdbBase.ClusterAddressInfo setHostManagerUrl(URL value)

  Set the host manager URL. Return this object to be able to chain operations.

• ​

  setIsPrimaryCluster

  public GPUdbBase.ClusterAddressInfo setIsPrimaryCluster(boolean value)

  Set whether this cluster is the primary one. Return this object to be able to chain operations.

• ​

  setHaStatus

  public GPUdbBase.ClusterAddressInfo setHaStatus(String value)

  Set the HA status (drained value) for this cluster. Return this object to be able to chain operations.

  Parameters:

  value - The HA status string (e.g., “drained”, “draining”, “not_drained”)

  Deprecated, for removal: This API element is subject to removal in a future version.

  Set whether this cluster has intra-cluster failover enabled. Return this object to be able to chain operations.

• ​

  doesClusterContainNode

  public boolean doesClusterContainNode(String hostName)

  Checks if the given hostname (or IP address) is part of this cluster.

  Returns:
