Thanks Cheng For the FIP, the design overall looks good to me.

>> When lake committer needs to find out the bucket end offset of committed 
>> lake snapshot, it has to reconstruct this information by reading the entire 
>> artificial bucket and offset columns from lake as Lance format lacks 
>> bucketing and partitioning support.

About this part, I think current approach is pretty in-efficient, could we 
kickoff a discussion to support custom options(properties) in lance community 
as well?

Best,
Leonard
