Configuration parameters
Configuration parameters are settings that affect database behavior. You can use configuration parameters to enable, disable, or tune features related to different database aspects like Tuple Mover, security, Database Designer, or projections. Configuration parameters have default values, stored in the Vertica database.
You can modify certain parameters to configure your Vertica database in two ways:
Before you modify a database parameter, review all documentation about the parameter to determine the context under which you can change it. Some parameter changes require a database restart to take effect. The CHANGE_REQUIRES_RESTART column in the system table CONFIGURATION_PARAMETERS indicates whether a parameter requires a restart. You can also query CONFIGURATION_PARAMETERS to determine what levels (node, session, database) are valid for a given parameter.
