09/16/2026, 11:23 PMdaft-lance version upgrade is basically done now.
There is one remaining issue I’d like to get the your thoughts on: the merge mode in write_lance.
The implementation semantics of merge were not very clear(mixed with create, append, merge), and exposes quite a few Lance-specific details at the Daft layer. There are also some corner cases that make the behavior harder to define and maintain consistently.
I’m wondering whether it would make sense to deprecate mode="merge" in write_lance and instead let users use the merge APIs provided directly by the daft-lance package, e.g. merge_columns, for this kind of operation.
What do you think?Robert Howell
