NDB Cluster Configuration Files Version (or later) NDB 8.0.13 Type or units integer Default 2 Range 2 - 72 Restart Type S (NDB 8.0.13) This parameter directly controls the number of execution threads used by  ndbmtd , up to a maximum of 72. Although this parameter is set in  [ndbd]  or  [ndbd default]  sections of the  config.ini  file, it is exclusive to  ndbmtd  and does not apply to  ndbd . Setting  MaxNoOfExecutionThreads  sets the number of threads for each type as determined by a matrix in the file  storage/ndb/src/kernel/vm/mt_thr_config.cpp . This table shows these numbers of threads for possible values of  MaxNoOfExecutionThreads . Table 23.12 MaxNoOfExecutionThreads values and the corresponding number of threads by thread type (LQH, TC, Send, Receive).
