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. The param_description, param_type, param_default, param_min, param_max, param_mandatory, and param_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.
