> a table with precombineField use diff merge into sql has different result.
> If merge sql with matchAction will have no dup key result, but when merge sql only has insertAction will have dup result if we not set `hoodie.combine.before.insert=true`.
> I think merge into for the same table need has consistent behavior.
