Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Translates a committed dependency write into a view's pending maintenance — a summary delta on a warm delta-maintainable view, otherwise a scoped (or, when the partition key cannot be derived, widened) recompute — and emits the maintenance instrumentation event for the path taken.
