Research direction

Start by reviewing the @BlobTrigger annotation and its current parameter-binding behavior in the Java library. Compare the requested method-level trigger, HEAD request, path forwarding, and @BindingName size binding with the existing annotations. Done would require a decided API design and tests showing blob paths can be queued without loading blob content.

Written by the indexing model from the issue text.

Description

Is it possible or could it be possible to use @BlobTigger without actually getting the content of the blob.

The use case for this is if you wanted to just send the path of the blob to a queue, which then would process the content of the blob. You wouldn't need say the whole content of a 2GB file to do that.

For example if @BlobTrigger was changed to be allowed as a method annotation as well as a parameter annotation.

Then the back end code would do a HEAD call to check if the blob exists and then call the method.

Plus you could also add @BindingName to have the size of the blob passed into the function.

P.S. I am aware that EventGrid is another way to have triggers on blobs
