Intermediate File Logging
An Intermediate File Logging job reads transactional data from MQ or JMS and performs continuous INSERT, UPDATE, and DELETE operations in a Teradata Database table, while simultaneously loading a duplicate data stream into an external flat file that can serve as an archive or backup file of the data that has been loaded.
Intermediate File Logging requires use of multiple APPLY clauses, one for the operator writing to Teradata Database and one for the operator writing to the external flat file.
The DataConnector operator is used twice in the job script:
Note that the two DataConnector operator definitions differ in content, in addition to the common required attributes:
