> I was looking at this code yesterday while using it in IOx --
> https://github.com/influxdata/influxdb_iox/pull/703
> Even though Schema::try_merge requires a slice of Schemas (not schema refs),
> it copies all of its fields. This is not ideal in the common case where most
> of the fields in the Schema will be the same
