<note>
  At least one of max_age, [max_docs](https://www.elastic.co/elastic/docs-builder/docs/2341/reference/elasticsearch/curator/option_max_docs), [max_size](https://www.elastic.co/elastic/docs-builder/docs/2341/reference/elasticsearch/curator/option_max_size) or any combinations of the three are required as `conditions:` for the [Rollover](https://www.elastic.co/elastic/docs-builder/docs/2341/reference/elasticsearch/curator/rollover) action.
</note>

The maximum age that is allowed before triggering a rollover. It *must* be nested under `conditions:` There is no default value.  If this condition is specified, it must have a value, or Curator will generate an error.
Ages such as `1d` for one day, or `30s` for 30 seconds can be used.
