Alter table would change columns (the structure) of a table. Adding or deleting a column, for instance.
Upserts would add (or edit) rows of an existing table. ALTER TABLE <https://docs.scylladb.com/getting-started/ddl/#id10> vs. UPDATE <https://docs.scylladb.com/getting-started/dml/#update-statement> (These docs are for Scylla, but Cassandra should be the same or similar for Datastax.)
