Package com.bigdata.bop.joinGraph.rto

Interface Summary

Interface	Description
JoinGraph.Annotations	Known annotations.
JoinGraph.Attributes	IQueryAttributes names for the JoinGraph.

Class Summary

Class	Description
EdgeSample	A sample produced by a cutoff join.
JGraph	A runtime optimizer for a join graph.
JoinGraph	A join graph with annotations for estimated cardinality and other details in support of runtime query optimization.
Path	A join path is an ordered sequence of N vertices and represents an ordered series of N-1 joins.
PathIds	An ordered array of bop identifiers which can be used as a signature for a join path segment.
SampleBase	Base class for a sample taken from a vertex (access path) or edge (cutoff join).
TestAll	Aggregates test suites into increasing dependency order.
TestJGraph	Test suite for JGraph, which is the core implementation of the runtime query optimizer logic.
TestJoinGraph	Unit tests for the JoinGraph operator.
Vertex	A vertex of the join graph is an annotated relation (this corresponds to an IPredicate with additional annotations to support the adaptive query optimization algorithm).
VertexSample	A sample of a Vertex (an access path).

Enum Summary

Enum	Description
EstimateEnum	Type safe enumeration describes the edge condition (if any) for a cardinality estimate.
