MySQL Cluster Manager 1.3 User Manual  /  Attribute Summary Tables  /  API Node Configuration Parameters

B.3 API Node Configuration Parameters

  • ApiVerbose: Enable NDB API debugging; for NDB development

  • ArbitrationDelay: When asked to arbitrate, arbitrator waits this many milliseconds before voting

  • ArbitrationRank: If 0, then API node is not arbitrator. Kernel selects arbitrators in order 1, 2

  • AutoReconnect: Specifies whether an API node should reconnect fully when disconnected from the cluster

  • BatchByteSize: The default batch size in bytes

  • BatchSize: The default batch size in number of records

  • ConnectBackoffMaxTime: Specifies longest time in milliseconds (~100ms resolution) to allow between connection attempts to any given data node by this API node. Excludes time elapsed while connection attempts are ongoing, which in worst case can take several seconds. Disable by setting to 0. If no data nodes are currently connected to this API node, StartConnectBackoffMaxTime is used instead.

  • ConnectionMap: Specifies which data nodes to connect

  • DefaultHashMapSize: Set size (in buckets) to use for table hash maps. Three values are supported: 0, 240, and 3840. Intended primarily for upgrades and downgrades to and from NDB 7.2.7+; see the documentation before attempting to use.

  • DefaultOperationRedoProblemAction: How operations are handled in the event that RedoOverCommitCounter is exceeded

  • ExecuteOnComputer: String referencing an earlier defined COMPUTER

  • ExtraSendBufferMemory: Memory to use for send buffers in addition to any allocated by TotalSendBufferMemory or SendBufferMemory. Default (0) allows up to 16MB.

  • HeartbeatThreadPriority: Set heartbeat thread policy and priority for API nodes; see manual for allowed values

  • HostName: Host name or IP address for this SQL or API node.

  • Id: Number identifying MySQL server or API node (Id). Now deprecated; use NodeId instead.

  • MaxScanBatchSize: The maximum collective batch size for one scan

  • NodeId: Number uniquely identifying the SQL node or API node among all nodes in the cluster.

  • StartConnectBackoffMaxTime: Same as ConnectBackoffMaxTime except that this parameter is used in its place if no data nodes are connected to this API node.

  • TotalSendBufferMemory: Total memory to use for all transporter send buffers

  • wan: Use WAN TCP setting as default
