Description
Currently it is only possible to add one column at a time in an alter table statement. It would be great if we could add multiple columns at a time.
The primary reason for this is that adding each column individually seems to take a significant amount of time (at least on my development machine), I know all the columns I want to add, but don't know them until after the initial table is created.
As a secondary consideration it brings CQL slightly closer to SQL where most databases can handle adding multiple columns in one statement.
