Does Cassandra support TTL for the Counter column family?
Specifically we use Hector as a client to Cassandra and I didn't find any API receiving TTL as a parameter. At least HFactory.createCounterColumn doesn't have TTL argument.

No. TTL expiration does not exist for counter columns. See CASSANDRA-2103 for background on why this feature doesn't make sense for Cassandra counter columns.
