Support for GCS PMPU?

[ggoggam]

I was trying out GCS blockstore as backend and noticed that pre signed multipart upload is not supported; it is supported with S3 though.

I see GCS PMPU implementation in the lakeFS source, but it seems such behavior is not documented in the API docs.

Can anyone from the lakeFS team answer this?

Hi, sorry for the delay in replying. Indeed this is not supported on GCS. GCS does support multipart, but not presigning. Sources.
As always, patches welcome!
