The Blob Store REST API allows storing binary objects in Solr. The primary use case for this is to store entity extraction models, lookup lists or exclusion lists for use in index pipelines. This may include the entity extraction models and lookup lists included with Fusion in the https://FUSION_HOST:FUSION_PORT/data/nlp directory, or files that you have created on your own. You can also work with blobs in the Fusion UI using the blob manager. Blobs uploaded to Solr with this REST API are stored in the system_blobs collection.

​
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:8764/api/blobs/myplugin?resourceType=plugin:connector' --data-binary @myplugin.zip
The complete list of valid values for resourceType is below:
TypeDescription
bananaA Banana dashboard
catalogAn analytics catalog
driver:jdbcA Upload a JDBC Driver to Fusion Server
file:js-indexA JavaScript file for use with a Managed Javascript index stage.
file:js-queryA JavaScript file for use with a Managed Javascript query stage.
fileAny uploaded file, such as from the Quickstart or the Index Workbench.
model:ml-modelA machine learning model (Fusion AI only)
model:open-nlpAn OpenNLP model (Fusion AI only)
otherA blob of unknown type If no resourceType is specified on upload, “other” is assigned by default.
plugin:connectorA Fusion 4.x connector

Examples

​
Upload a JavaScript file to the blob store

REQUEST 
curl -u USERNAME:PASSWORD -X PUT -H 'Content-Type: text/javascript' --data-binary @query-pipeline-js-stage.js https://FUSION_HOST:8764/api/blobs/query-pipeline-js-stage.js?resourceType=file:js-query
The response is empty.

​
Verify that the JavaScript blob was uploaded

REQUEST 
curl -u USERNAME:PASSWORD https://FUSION_HOST:8764/api/blobs?resourceType=file:js-query
RESPONSE 
[{
  "id": "query-pipeline-js-stage.js",
  "path": "/query-pipeline-js-stage.js",
  "dir": "/",
  "filename": "query-pipeline-js-stage.js",
  "contentType": "text/javascript",
  "size": 0,
  "modifiedTime": "2018-09-11T16:23:17.743Z",
  "version": 1611328911094841344,
  "md5": "d41d8cd98f00b204e9800998ecf8427e",
  "metadata": {
    "resourceType": "file:js-query"
  }
}]

​
Upload an OpenNLP sentence model binary file to the blob store

REQUEST 
curl -u USERNAME:PASSWORD -X PUT --data-binary @data/nlp/models/en-sent.bin -H 'Content-type: application/octet-stream' https://FUSION_HOST:8764/api/blobs/sentenceModel.bin
In this example, we have changed the name of the blob during upload by giving it a different ID. The file is named ‘en-sent.bin’ but we have defined the ID of this to ‘sentenceModel.bin’. When we use this blob in an index pipeline, we would refer to it by the ID we have given it.

​
Get the manifest for a sentence OpenNLP model we have previously saved in the blob store

REQUEST 
curl -u USERNAME:PASSWORD -X HEAD https://FUSION_HOST:8764/api/blobs/sentenceModel.bin
RESPONSE 
{
  "name": "sentenceModel.bin",
  "contentType": "application/octet-stream",
  "size": 98533,
  "modifiedTime": "2014-09-08T18:50:07.559Z",
  "version": 1478704189996531712,
  "md5": "3822c5f82cb4ba139284631d2f6b7fde"
}

​
Upload a JDBC driver, using slashes in the blob name

REQUEST 
curl -u USERNAME:PASSWORD -X PUT --data-binary @postgresql-42.0.0.jar -H 'Content-length: 6' -H 'Content-type: application/octet-stream' https://FUSION_HOST:8764/api/blobs/good/to/go/jdbcDriverFile?resourceType=driver:jdbc
RESPONSE 
{
  "name": "good/to/go/jdbcDriverFile",
  "contentType": "application/octet-stream",
  "size": 6,
  "modifiedTime": "2017-04-04T15:58:32.856Z",

  }
}

​
Get the JDBC driver that was uploaded
