tensorflow::serving::AspiredVersionsManager

#include <aspired_versions_manager.h>

A manager that implements the Target<Loader> API which uses aspired-versions callbacks to dictate which servable versions to load.

Summary

This manager also uses that API to infer which ones to unload: If a given servable version is currently loaded, and is omitted from an aspired-versions callback invocation pertaining to its servable stream, this manager interprets that omission as an implicit instruction to unload the version. See below for details.

(The implicit-unload semantics facilitates stateless Source implementations, whereby a given iteration of the Source's logic simply decides which versions of a servable ought to be loaded, without needing to know what it has decided in the past.)

This manager makes transitions between versions of a servable stream using a configured AspiredVersionPolicy. The manager prefers unloading before loading to free up resources in the server when deciding among transitions suggested by the policy.
