Hi, Richard.  The raw resource accepts a "keys" parameter to help with
this case.

The default, equivalent to keys=true, will provide a response with all
the keys in it, like you received above.

keys=false will omit the "keys" field from the response.

keys=chunked will provide the keylist via chunked HTTP encoding.  Each
chunk will have a portion of the keylist, {"keys":["x","y","z",...]},
so the client may consume it a little bit at a time.

Does that solve the issue for your use case?
