Q. I suggest two possible errors when doing an upsert: it is illegal to modify a primary-key field and it is illegal to use upsert on a space that has a unique secondary index.

I’m curious to know why Tarantool does not support these if there is a unique secondary index.

A. In these cases, we must check the input arguments against the space schema, which is quite expensive.
