Notes 23.5.14.42 The ndbinfo resources Table 4573 ndbinfo: The NDB Cluster Information Database • process_name • service_URI • MGM : Management node. • NDB : Data node. • API : API or SQL node. • node_id The  resources  table contains the following columns: These resources are sometimes known as  super-pools . This table provides information about data node resource availability and usage. Additional path information may be included in the  service_URI  value for an SQL node reflecting various configuration options. For example,  mysql://198.51.100.3/tmp/mysql.sock indicates that the SQL node was started with the  skip_networking  system variable enabled, and mysql://198.51.100.3:3306/?server-id=1  shows that replication is enabled for this SQL node. service_URI  shows the service network address. For management nodes and data nodes, the scheme used is  ndb:// . For SQL nodes, this is  mysql:// . By default, API nodes other than SQL nodes use  ndb://  for the scheme; NDB API applications can set this to a custom value using Ndb_cluster_connection::set_service_uri() . regardless of the node type, the scheme is followed by the IP address used by the NDB transporter for the node in question. For management nodes and SQL nodes, this address includes the port number (usually 1186 for management nodes and 3306 for SQL nodes). If the SQL node was started with the  bind_address  system variable set, this address is used instead of the transporter address, unless the bind address is set to  * ,  0.0.0.0 , or  :: . The  process_name  column shows the name of the running executable. For management nodes, this is  ndb_mgmd . For data nodes, this is  ndbd  (single-threaded) or  ndbmtd  (multithreaded). For SQL nodes, this is  mysqld . For other types of API nodes, it is the name of the executable program connected to the cluster; NDB API applications can set a custom value for this using Ndb_cluster_connection::set_name() . angel_process_id  is the system process ID for the node’s angel process, which ensures that a data node or SQL is automatically restarted in cases of failures. For management nodes and API nodes other than SQL nodes, the value of this column is  NULL . process_id  is the node executable’s process ID as shown by the host operating system using a process display application such as  top  on Linux, or the Task Manager on Windows platforms. For an executable shipped with the NDB Cluster distribution,  node_version  shows the software Cluster version string, such as  8.0.26-ndb-8.0.26 . The  node_type  column displays one of the following three values: node_id  is the ID assigned to this node in the cluster. Service URI of this node (see text) Name of the executable
