Description

The current Elastic implementation does not use an IndexTracker like the Lucene counterpart. IndexTracker is a component that keeps track of all indexes in a repository (all readers, writers, and definitions using Observers (see LuceneIndexProvider). Without this component, every operation has to load data (especially IndexDefinitions) from the underneath data store.
