[BionIT]

Describe the blog post your would like to write
In 2.4 release, multiple data source feature was introduced together with data source client as well as data source management portal to allow users to add new data source to the dashboards and query local and remote OpenSearch clusters.

In 2.13 release, we introduced a feature in data source plugin to allow external dashboards plugins to register their API schema, and in 2.14 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 dashboards plugins including anormaly detection, maps, and enabled multiple data source at 2 core plugins including TSVB and Region Map.

This blog would describe how users can interact with multiple data source from core or external plugins.
