The batch argument indicates that Sqoop must export data in batches instead of exporting data row by row.
Use the following syntax:
--batch
You can configure the batch argument to improve the performance.
The batch argument is required when you configure Sqoop in the following scenarios:
You write data to a Vertica target.
You write data to an IBM DB2 for z/OS target.
You write data to a Teradata target by running the mapping with a generic JDBC connector instead of a TDCH specialized connector for Sqoop. You can invoke the generic JDBC connector by configuring the --driver and --connection-manager Sqoop arguments in the JDBC connection.
