    +1 with just a few superficial comments.
    Reading back through the discussion I see that there are many ideas for future performance
enhancements. If not already suggested I'd like to consider skipping staging for fixed length
    I'm missing why we can't update in place with smaller records. The deserializer is responsible
for detecting the end of the record and we wouldn't need to change the pointer value when
replacing with a smaller record.
    CombineHint.NONE can be implemented in a new PR since this looks to be ready as-is.
