Member Enumeration Documentation

attribute

enum turi::query_eval::query_operator_attributes::attribute

Enumerator
NONE	No attribute.
SUB_LINEAR	A linear input operator consumes input sources at the same rate and emit outputs at the same rate
SOURCE	A sublinear operator consumes input sources at the same rate, but may generate output at a different lower or higher rate
LOGICAL_NODE_ONLY	A source operator is a direct source from an sframe or sarray and has no inputs.
SUPPORTS_SKIPPING	A node that never turns into an executor; it simply is a logical node only, possibly used in the query optimizer.
