Managed JavaScript Query Stage
This stage manipulates a query using a script from the blob store.  The script must have the blob type file:js-query.

Uploading a JavaScript blob
In Fusion 5.6, 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://FUSION_HOST:FUSION_PORT/api/apps/APP_NAME/blobs/query-pipeline-js-stage.js?resourceType=file:js-queryOpen the blob manager to verify that the new blob is present:

Referencing a JavaScript blob
Use any of the following formats for the ref/Script Reference configuration field:
query-pipeline-js-stage.jsblob:query-pipeline-js-stage.jsurn:x-fusion:blob:query-pipeline-js-stage.js| The examples above use query-pipeline-js-stage.jsas the blob ID. | 
Edit JavaScript
For Fusion 5.4.x and later, select Edit in the Script Reference field to edit JavaScript directly in the Fusion UI.
