Blob Storage

Fusion accepts large binary objects (blobs) for upload, and stores them in Solr. Blob uploads are used to install models, lookup lists, JDBC drivers, connectors, and more.

Blob Types

A resourceType query parameter can be used to specify the a blob type. For example, specify plugin:connector when uploading a connector, like this:

curl -H 'content-type:application/zip' -X PUT 'fusion-host:{api-port}/api/blobs/myplugin?resourceType=plugin:connector' --data-binary

The complete list of valid values for resourceType is below:

Type Description


A Banana dashboard




Any uploaded file, such as from the Quickstart or the Index Workbench.


A machine learning model (Fusion AI only)


An OpenNLP model (Fusion AI only)


A blob of unknown type

If no resourceType is specified on upload, "other" is assigned by default.


The Blob manager

In addition to the Blob Store API, the Fusion UI provides an interface to the blob store in the Fusion workspace at System > Blobs:

    In Fusion 4.1, it is not possible to upload a blob of type file:js-index or file:js-query using the Fusion UI. Instead, use the Blob Store API. These blob types become visible in the blob manager after upload.
  • Select an uploaded blob to view, replace, or delete it:
