tGreenplumBulkExec
Improves performance when loading data in a Greenplum
database.
The tGreenplumOutputBulk and
tGreenplumBulkExec components are used
together in a two step process. In the first step, an output file is generated. In the
second step, this file is used in the INSERT statement used to feed a database. These
two steps are fused together in the tGreenplumOutputBulkExec component, detailed in a separate section. The
advantage of using a two step process is that it makes it possible to transform data
before it is loaded in the database.
tGreenplumBulkExec performs an Insert
action on the data.
