If we don't specify a `max_cache_age`on a datagroup, will it default to the 1 hour?

According to the datagroup docs, the cached results will be busted the next time the sql_trigger_value changes. So, no, the cached results will not expire in one hour.

The cache age will, however, be affected by explore-level or model-level max_cache_age or persist_for values.
