ndbinfo: The NDB Cluster Information Database • transid • state • count_operations • outstanding_operations • inactive_seconds • client_node_id • client_block_ref Transaction ID Operation state (see text for possible values) Number of stateful operations in the transaction Operations still being executed by local data management layer (LQH blocks) Time spent waiting for API Client node ID Client block reference The  mysql_connection_id  is the same as the connection or session ID shown in the output of  SHOW PROCESSLIST . It is obtained from the  INFORMATION_SCHEMA  table NDB_TRANSID_MYSQL_CONNECTION_MAP . block_instance  refers to an instance of a kernel block. Together with the block name, this number can be used to look up a given instance in the  threadblocks  table. The transaction ID ( transid ) is a unique 64-bit number which can be obtained using the NDB API’s getTransactionId()  method. (Currently, the MySQL Server does not expose the NDB API transaction ID of an ongoing transaction.) The  state  column can have any one of the values  CS_ABORTING ,  CS_COMMITTING ,  CS_COMMIT_SENT , CS_COMPLETE_SENT ,  CS_COMPLETING ,  CS_CONNECTED ,  CS_DISCONNECTED ,  CS_FAIL_ABORTED , CS_FAIL_ABORTING ,  CS_FAIL_COMMITTED ,  CS_FAIL_COMMITTING ,  CS_FAIL_COMPLETED , CS_FAIL_PREPARED ,  CS_PREPARE_TO_COMMIT ,  CS_RECEIVING ,  CS_REC_COMMITTING , CS_RESTART ,  CS_SEND_FIRE_TRIG_REQ ,  CS_STARTED ,  CS_START_COMMITTING , CS_START_SCAN ,  CS_WAIT_ABORT_CONF ,  CS_WAIT_COMMIT_CONF ,  CS_WAIT_COMPLETE_CONF , CS_WAIT_FIRE_TRIG_REQ . (If the MySQL Server is running with  ndbinfo_show_hidden  enabled, you can view this list of states by selecting from the  ndb$dbtc_apiconnect_state  table, which is normally hidden.) In  client_node_id  and  client_block_ref ,  client  refers to an NDB Cluster API or SQL node (that is, an NDB API client or a MySQL Server attached to the cluster). The  block_instance  column provides the  DBTC  kernel block instance number. You can use this to obtain information about specific threads from the  threadblocks  table. 23.5.14.47 The ndbinfo table_distribution_status Table Notes 4582
