Very few, if any, non-memory databases are likely to be able to "handle" a
"million" "rows" in a small number of seconds.

The default timeouts for Cassandra operations are in the order of small (in
some cases single) numbers of seconds.

This very strongly suggests that the operation you are trying to do, and
design you are exploring, is not inherently very "Cassandric." :D
