Hi,

I can't find a way with new reactive stream api to add a custom row on fs.files collection of gridfs.

On my old (that run in production) I was able to add custom row on 
com.mongodb.gridfs.GridFSInputFile using

gridFSInputFile.put("CUSTOM_ROW", myCustomRow);

The com.mongodb.reactivestreams.client.gridfs.GridFSBucket only allows to add metadata via GridFSUploadOptions.

But I've 16TB on my mongodb and I can't change the structure of my document.

By the way, this customRow,  is also my sharding key...

Can you add this features (or suggest me a workaround)?

regards
