Stream Driver Required Attributes 
Attribute and Type Type Description
TD_BUFFER_MODE varchar Indicates which type of Stream method is used.
Valid Settings:
  • Default value is No.
  • Must be set to Yes when using the block Stream feature.
TD_INSTANCE_NUM integer Provides the instance number of the current instance.
  • If the current instance is the main instance, then the instance number is one.
  • If the current instance is a worker instance, then the instance number will be a value greater than one.
TD_LOG_TABLE varchar Provides the name of the restart log table for restart information. Each Stream driver job needs to use its own restart log table if multiple Stream driver jobs are executed concurrently.
If the restart log table name is not fully qualified, it is created under the user’s default (logon) database. Alternately, a working database can be specified using the TD_WORKINGDATABASE attribute. If the TD_WORKINGDATABASE attribute is used, the restart log table name must be fully qualified, even if the restart log table is going to reside in the default (logon) database.
TD_MAX_INSTANCES integer Provides the total number of instances (main and workers). Required when using multiple instances of the same driver in a main-worker environment.
TD_RESTARTMODE integer Required only before restarting and must be set to one before performing a restart.
TD_SYSTEM_OPERATOR varchar Specifies the type of driver being used (in this case, TD_STREAM).
TD_USER_NAME varchar Provides the name of the user for the Stream driver logon sessions.
TD_USER_PASSWORD varchar Specifies the password associated with the user name.
