Uses of IterativeMetadataContext in com.pervasive.datarush.ports.record

Methods in com.pervasive.datarush.ports.record with parameters of type IterativeMetadataContext

Modifier and Type	Method and Description
static void	MetadataUtil.negotiateParallelismBasedOnSourceAssumingParallelizableRecords(IterativeMetadataContext ctx) Uses the maximum of the input ports' parallelism as the max parallelism of the operator If there are no parallel inputs, this will use Integer.MAX_VALUE as its parallelism, forcing a "scatter" from the inputs.
void	RecordPort.setIterationStagingOptions(IterativeMetadataContext ctx, DatasetOptions options) Sets the staging options for this input port.
