naming variables separately is more readable
(mutable, instance): (
SkipMap<Timestamped<<A::Record as Record>::Key>, Option<A::Record>>,

there is no need to call this method self.schema.record_instance.arrow_schema::<R>(), use primary_key_index directly

the lack of size() implementation should cause the data to be unable to trigger Compaction (the threshold will not be reached)

I think macros can be used to simplify this to simply implement most types.

can this method be used to implement another trait such as StaticRecord instead of unreachable! ?
