Uses of Operator in org.apache.druid.query.operator

Classes in org.apache.druid.query.operator that implement Operator

Modifier and Type	Class	Description
class	AbstractPartitioningOperator
class	AbstractSortOperator	Base class for sort operators.
class	GlueingPartitioningOperator	This glueing partitioning operator is supposed to continuously receive data, and output batches of partitioned RACs.
class	LimitTimeIntervalOperator
class	NaivePartitioningOperator	This naive partitioning operator assumes that it's child operator always gives it RowsAndColumns objects that are a superset of the partitions that it needs to provide.
class	NaiveSortOperator	A naive sort operator is an operation that sorts a stream of data in-place.
class	PartitionSortOperator	This operator sorts rows inside partitioned RACs, on the sort columns.
class	ScanOperator	A scan operator is really just a way to push down various things that can be lazily applied when data needs to actually be read.
class	SegmentToRowsAndColumnsOperator
class	SequenceOperator
class	WindowProcessorOperator	An Operator that applies a Processor, see javadoc on that interface for an explanation.
