21.6.15.8 The ndbinfo config_params Table

The config_params table is a static table which provides the names and internal ID numbers of and other information about NDB Cluster configuration parameters.

The config_params table contains the following columns:

• param_number
  The parameter's internal ID number
• param_name
  The name of the parameter
• param_description
  A brief description of the parameter
• param_type
  The parameter's data type
• param_default
  The parameter's default value, if any
• param_min
  The parameter's maximum value, if any
• param_max
  The parameter's minimum value, if any
• param_mandatory
  This is 1 if the parameter is required, otherwise 0
• param_status
  Currently unused

Notes

In NDB Cluster 7.5 (and later), this table is read-only. Theparam_description,param_type, param_default,param_min, param_max,param_mandatory, andparam_status columns were all added in NDB 7.5.0.

Although this is a static table, its content can vary between NDB Cluster installations, since supported parameters can vary due to differences between software releases, cluster hardware configurations, and other factors.
