 Before 2.4 release, OpenSearch Dashboards only works with a single OpenSearch cluster, and it is impossible to view data from different clusters within the dashboards. 
 
-In 2.4, multiple data source feature was introduced together with data source management UI portal to allow users to add new data source to the dashboards, create index patterns based on those data sources, and execute queries against a specific connected data source. In 2.6 release, AWS signature Version 4 was added as one authentication type supported by multi data source in addition to basic auth. Onwards, multi data source support at core plugin including dev tools was added in 2.7 release, sample data support was added in 2.9 release, then added in for Vega visualization in 2.13. File based saved objects import sourced from multi data source was added into OpenSearch Dashboards in 2.12.

-In this release, to ensure users that have been using the multiple data source feature to have a consistent experience in the dashboards, we enabled multiple data source at 8 OpenSearch Dashboards plugins including index management, machine learning, search relevance, anomaly detection, maps, security, notification, etc, and enabled multiple data source at 2 core plugins including TSVB and Region Map. In addition, we introduced default data source feature which will be the default option chosen for all plugins pages that support multi data source.

 ## User scenario - Single panel of glass of data
 Use one OpenSearch Dashboards to present data from multiple OpenSearch Cluster
 
 ### Case 1
-In large corporation, user’s data has been distributed in different datasource, before multiple datasource was introduced. User has to put data into centralized storage before they could analyze it. With the build-in support of multiple datasource, OpenSearch dashboards could present data from multiple data sources within a single dashboard. Starting 2.14, we support additional visualization type including Vega, TSVB, Region Map, in addition to index pattern based visualizations.

+### Case 1 Manage indexes, streams, aliases, in a centralized place
 Before 2.14, index management within the dashboards allows to perform management operations on indexes within one OpenSearch cluster. With multi data source support added for the plugin in 2.14, all operations include create, read, update, delete (CRUD), mapping operations for indexes, index templates, and aliases living in different data sources can be completed in one dashboard. Using indexes as an example, indexes from different data sources can be displayed by switching source at the top navigation bar, and operations can be done by selecting a specific index then choose the desired option.
