How about implementing a freezing mechanism on counter columns.

If there are no more increments within "freeze" seconds after the last increments (it would be orders or day or so); the column would lock itself on increments and won't accept increment.

And after this freeze perioid, the ttl should work fine. The column will be gone forever after freeze + ttl seconds.
