How to deal with Schema Evolution in an API?

[rdick]

Hello,

I wasn't finding any specific methods where I could evolve a tables schema when querying an api with a custom connector.

Eg.
START: Table X - id, first_name, last_name
.
CHANGE: Table X - id, first_name, last_name, middle_name
.
How can we ensure that it will push this into the schema?
