Overview

Note:

This listener makes no attempt to avoid reindexing when no metadata has actually changed, or when real metadata changes won’t impact the indexed data. We trust that published metadata update events represent actual changes to object metadata, and that the indexing adapter optimizes reasonably for actual index document contents.

Reindexes resources when their metadata is updated.
