Data Export Process for Teradata JDBC FastExport

Data Export Process for Teradata JDBC FastExport

By default, archive, retirement, and restore jobs use Teradata JDBC FastExport to export data from Teradata. If you enable Teradata Parallel Transporter for an archive or retirement job, the job uses Teradata JDBC FastExport to export data from tables that have binary or large object datatypes such as BLOB and CLOB.
When you run a job, the job creates an SQL select PreparedStatement for the extract query. The job creates the URL connection string with parameters for Teradata JDBC FastExport.
The job creates the following URL connection string:
jdbc:teradata://$HOST/DATABASE=$SID,TMODE=ANSI,CHARSET=UTF16,TYPE=FASTEXPORT,SPOOLMODE=NOSPOOL,SESSIONS=$MAX_PARALLEL_SESSIONS
The job uses the Teradata source connection properties to populate the $HOST, $SID, and $MAX_PARALLEL_SESSIONS parameters.
If the target is a database, Teradata JDBC FastExport runs the query, streams the results in memory, and writes to the database.
If the target is the Data Vault, Teradata JDBC FastExport runs the query and writes the query results to compressed BCP files. Teradata JDBC FastExport saves the BCP files to the BCP file staging directory that is configured in the Data Vault target connection. The Data Vault Loader job moves the BCP files from the BCP file staging directory to the Data Vault.
