Attribute

SchemaMap (SMP)

Purpose

Specifies the name and location of the configuration file used to create the relational map of native data. The driver looks for this file when connecting to the server. If the file does not exist, the driver creates one.

Valid Values

string

where:

string
is the absolute path and filename of the configuration file, including the .config extension. For example, if SchemaMap is set to a value of C:\Users\Default\AppData\Local\Progress\DataDirect\Cassandra_Schema\MyServer.config, the driver either creates or looks for the configuration file MyServer.config in the directory C:\Users\Default\AppData\Local\Progress\DataDirect\Cassandra_Schema\.

Notes

  • When connecting to a server, the driver looks for the SchemaMap configuration file. If the configuration file does not exist, the driver creates a SchemaMap configuration file using the name and location you have provided. If you do not provide a name and location for a SchemaMap configuration file, the driver creates it using default values.
  • The driver uses the path specified in this connection option to store additional internal files.
  • You can refresh the internal files related to an existing relational view of your data by using the SQL extension Refresh Map. Refresh Map queries the Cassandra catalog tables and updates your internal files accordingly.

Default

The default is determined by the environment. The driver attempts to create the files in a subdirectory of the first available directory in the following order:

  • Windows
    • DD_HOME environment variable
    • LOCALAPPDATA environment variable
    • APPDATA environment variable
    • User’s home directory
    For Windows, the file path takes the following format: 
    available_location\Progress\DataDirect\Cassandra_Schema\user_name.config
  • UNIX/Linux
    • DD_HOME environment variable
    • User’s home directory
    For UNIX/Linux, the file path takes the following format: 
    available_location/progress/datadirect/Cassandra_schema/user_name.config
