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 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:

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.

Configuration

When entering configuration values in the UI, use unescaped characters, such as \t for the tab character. When entering configuration values in the API, use escaped characters, such as \\t for the tab character.
