This stage manipulates a query using a script from the blob store. The script must have the blob type file:js-query. See also: Custom JavaScript Stages For Query Pipelines.

​
Uploading a JavaScript blob

In Fusion 4.2, JavaScript blobs must be uploaded using the Blob Store API, like this: 
curl -u USERNAME:PASSWORD -X PUT -H 'Content-Type: text/javascript' --data-binary @query-pipeline-js-stage.js http://localhost:8764/api/apps/APP_NAME/blobs/query-pipeline-js-stage.js?resourceType=file:js-query
Open the blob manager to verify that the new blob is present: Uploaded JavaScript blob in the blob manager

​
Referencing a JavaScript blob

Use any of the following formats for the ref/Script Reference configuration field: 
query-pipeline-js-stage.js

blob:query-pipeline-js-stage.js

urn:x-fusion:blob:query-pipeline-js-stage.js
The examples above use query-pipeline-js-stage.js as the blob ID.
