public final class WriteToJDBC extends AbstractWriteToJDBC
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. The initial statement must be provided when this operator is
used in OVERWRITETABLE
mode.
Note that the WriteToJDBC
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
LogicalGraph#add(com.pervasive.datarush.operators.LogicalOperator, OperatorSettings)
method.
