> The current implementation is triggered when the "metadata.json" of an Iceberg table retains exactly one partition spec. We introduced the limitation because it is not trivial to apply Bucket Map Join when partition specifications have evolved.
> However, the restriction is too strict because the "metadata.json" is top-level metadata that includes the partition specs of all snapshots. This ticket would gather partition specs tied to only a related snapshot.
