> keyManagerImpl#listStatus for FSO buckets serves a KeyLocationList but might
> be large size of response (> 100 MB) and exceed the limit. The problem is
> KeyLocation field is large enough (> 1MB) so just listing some multi-part
> uploaded keys exceeds the limit. A possible solution is to reduce KeyLocation
> size by omitting pipeline fields.
> {quote}% ozone sh key ls /s3v/bucket --prefix=path/to/prefix
> RPC response exceeds maximum data length
> {quote}
>
> We checked a List<OzoneFileStatus> in our environment and it turned out that
> protobufs corresponding to some multi-part keys are larger than 1MB. AFAIK,
> the maximum IPC length is 100MB by default so it easily exceeds the limit.
