My main feedback is that we need to keep the schema parameter because we eventually need it to create bound partition spec.

The current implementation allows using partition_type_ cache based on tableschema_, but the given schema parameter may belong to a different schema version, which could lead to correctness issues.
Suggest adding schema_id to the cache key to ensure consistency.
such as:
std::unordered_map<int32_t, std::shared_ptr> partition_type_cache_;
