Brandon Williams commented on CASSANDRA-17894:
----------------------------------------------
bq. ISTM we could benefit from something like an executeSchemaChange() call
Or if the driver would handle it with every session.execute(), since that's how
we do all the schema changes. In any case that's refactoring for a different
ticket, we have 40+ instances of waits now.
bq. Seems to me with this method the default is none and create_ks gives 120?
The default is 10 in the driver, and we don't specify a wait_time in the vast
majority of our uses. Maybe it's better to run with what a client would
probably use until we have a problem?
