Document Extensions Overview
-
Document extensions are data entities associated with documents.
-
Document extensions are stored separately so that modifying an extension value (e.g. a counter or a time series entry) will not modify its parent document.
-
Creating or deleting an extension changes the parent document's meta-data. This document change may trigger indexing, ETL tasks, and various other operations.

Counters
RavenDB's distributed counters are numeric data variables that can be added to documents and used for various counting tasks. -
Attachments
Attachments are binary streams (videos, images, PDF, etc.) that can be bound to an existing document. -
Time Series
Time series are vectors of data that collect values over time, store the values consecutively across the cluster, and manage the collected data with high efficiency and performance. -
Revisions
Document Revisions are snapshots of documents and their extensions that can be created to give access to a document's history.
