IndicesIndexSettingsLifecycle [interface-IndicesIndexSettingsLifecycle]

Name	Type	Description
indexing_complete	SpecUtilsStringified	Indicates whether or not the index has been rolled over. Automatically set to true when ILM completes the rollover action. You can explicitly set it to skip rollover.
name	Name	The name of the policy to use to manage the index. For information about how Elasticsearch applies policy changes, see Policy updates.
origination_date	long	If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.
parse_origination_date	boolean	Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern ^.*- { date_format } - d+, where the date_format is yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format, for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.
prefer_ilm	boolean	string
rollover_alias	string	The index alias to update when the index rolls over. Specify when using a policy that contains a rollover action. When the index rolls over, the alias is updated to reflect that the index is no longer the write index. For more information about rolling indices, see Rollover.
