This looks good, but I have a couple asks.

I think this initialization should stay, for the case meta is not defined in the json?

@rjernst I was thinking of using null for this case. Or is empty map better?
And which value must be used for unset meta?

I'm fine with null. I had thought changing this from emtpy map to null would require updating Mapping.toXContent. However, it looks like it currently handles both cases. I would update that to remove the empty case (which means explicitly putting an empty _meta would be serialized, not disappear).

I would flip this logic to remove negations. ie mergeWith.meta == null ? meta : mergeWith.meta. Positive logic is easier to reason about. It might also be better to just move it out to a local instead of trying to inline it.

@alexshadow007 Can you update Mapping.toXContent as I suggested? |
