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. This table can also be used in conjunction with the config_values table for obtaining realtime information about node 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
This table is read-only.
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.
