Module algorithm 

Graph algorithm plugins.

Two surfaces: AlgorithmProvider for black-box algorithms (the existing uni-algo library style), and PregelProgramProvider for vertex-program-style algorithms the host’s Pregel executor runs.

Structs

AlgorithmContext

Per-invocation context passed to an AlgorithmProvider.

AlgorithmSignature

Static signature of an algorithm.

ComputeOutcome

Outcome of a vertex’s compute step.

PregelSignature

Signature of a Pregel-style vertex program.

PregelStats

Statistics surfaced to the Pregel host between supersteps.

Enums

AggregationMode

Synchronization model for Pregel programs.

Traits

AlgorithmHost

Opaque host callback surfacing graph access to plugin algorithms.

AlgorithmProvider

A black-box graph algorithm.

PregelProgramProvider

A Pregel-style vertex program plugin.
