public final class DeleteFromJDBC extends AbstractWriteToJDBC implements RecordPipelineOperator
Key fields must be specified in the
operator properties. Key field values will be used within generated
database delete statements.
Initial and
final SQL
statements can be provided. The initial statement is run before any input
data is handled. The final statement is executed after all input data has
been processed.
Note that the DeleteFromJDBC operator is parallelized. Each parallel
instance will open a separate connection to the target database. To limit the
number of database connections used by this operator, tune down the operator parallelism level.
To set the parallelism level create an OperatorSettings instance with
maximum parallelism set to the wanted level. The operator settings can then be
passed as a parameter to the
