   > It's no longer "pre" combine/ deduplicate incoming batch, but rather combine on write
   
   I agree, the `preCombine` is kind of confusing and for the literal meanings, it seems to do the payload merging for in-mem records, while the `hoodie.payload.ordering.field` is more straight-forward at lest for the option name, we know that it can be used for both in-mem mering and base + delta combining.
   
   In general, `preCombine` is not a good name because it exposed the physical characteristic to users, no one is familiar with what a `Combine` or `preCombine` is.
