The JDBC V2 connector is supported, and fetches documents from a relational database via SQL queries. Under the hood, this connector implements the Solr DataImportHandler (DIH) plugin.Fusion stores JDBC drivers in the blob store. You can upload a driver using the Fusion UI or the Blob Store API.

How to install a JDBC driver using the API
-
Upload the JAR file to Fusion’s blob store using the
/blobs/{id}endpoint. Specify an arbitrary blob ID, and aresourceTypevalue ofplugin:connector, as in this example:Success response:Fusion automatically publishes the event to the cluster, and the listeners perform the driver installation process on each node.If the blob ID is identical to an existing one, the old driver will be uninstalled and the new driver will installed in its place. To get the list of existing blob IDs, run:curl -u USERNAME:PASSWORD https://FUSION_HOST:FUSION_PORT/api/blobs -
To verify the uploaded driver, run:
