We now support reactive GridFS using MongoDB's reactive GridFS API. Files can be consumed and provided as binary stream.
ReactiveGridFsOperations operations = …;
Publisher<DataBuffer> buffers = …
Mono<ObjectId> id = operations.store(buffers, "foo.xml");
Flux<DataBuffer> download = operations.getResource("foo.xml").flatMap(ReactiveGridFsResource::getDownloadStream);
