Tanvi Penumudy commented on HDDS-7715:
--------------------------------------
{quote}The new lightweight listStatus API would be used for:
* {{o3}} CLI: ({{{}ozone sh key list{}}})
* S3 ListObject requests
The existing listStatus API will continue being used for:
* {{ofs}} commands
{quote}
We intend to stick with the existing listStatus API for the {{ofs}} client over
the newer lightweight implementation as it appears that the
BasicOzoneFileSystem, BasicRootedOzoneFileSystem#convertFileStatus rely on the
BlockLocations specific information - [~pifta] your insights around this should
help, thanks!

> 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.

> 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- 128MB by default so it easily exceeds the
> limit.
