What's the support policy for API versions? Do we increment API versions for breaking API changes (this seems reasonable and likely)? And do we support previous API versions for some period of time?
If the answer to both of those questions is "yes" , then what is the purpose of fast major verison releases? If we ship Polaris 2.0, shouldn't the service still support the v1 APIs? For me, a 2.0 release should mean pretty radical changes - new features, such as non-Iceberg table support, delegated Authz policies, etc. On Mon, Oct 21, 2024 at 11:53 AM Yufei Gu <flyrain...@gmail.com> wrote: > I'm not opposed to rapid evolution, but I’m trying to understand the > reasoning behind the fast major version.
