TTL interval

Documents that have a ttl value set need to be deleted once they have expired. How and how often they are deleted is controlled by the following dynamic cluster settings:

indices.ttl.interval
How often the deletion process runs. Defaults to 60s.
indices.ttl.bulk_size
The deletions are processed with a bulk request. The number of deletions processed can be configured with this settings. Defaults to 10000.
