ndbinfo: The NDB Cluster Information Database | 6 | 3 | recv | receive thread, performing receive and polling for new receives | +---------+--------+-------------+------------------------------------------------------------------+ 8 rows in set (0.01 sec) NDB 8.0.23 introduces the possibility to set either of the  ThreadConfig  arguments  main  or  rep  to 0 while keeping the other at 1, in which case the thread name is  main_rep  and its description is  main and rep thread, schema, distribution, proxy block and asynch replication handling . It is also possible beginning with NDB 8.0.23 to set both  main  and  rep  to 0, in which case the name of the resulting thread is shown in this table as  main_rep_recv , and its description is  main, rep and recv thread, schema, distribution, proxy block and asynch replication handling and handling receive and polling for new receives . The  threadstat  table provides a rough snapshot of statistics for threads running in the  NDB  kernel. The  threadstat  table contains the following columns: Node ID Thread ID Thread name Number of loops in main loop Number of signals executed Number of times waiting for additional input Number of priority A signals sent to own node Number of priority B signals sent to own node Number of priority A signals sent to remote node Number of priority B signals sent to remote node 4590 • os_tid • c_r_sent_priob • c_r_sent_prioa • c_l_sent_priob • c_l_sent_prioa • c_wait • c_exec • c_loop • thr_nm • thr_no • node_id 23.5.14.54 The ndbinfo threadstat Table
