* [ILM] Add date setting to calculate index age Add the `index.lifecycle.origination_date` to allow users to configure a custom date that'll be used to calculate the index age for the phase transmissions (as opposed to the default index creation date). This could be useful for users to create an index with an "older" origination date when indexing old data. Relates to #42449. * [ILM] Don't override creation date on policy init The initial approach we took was to override the lifecycle creation date if the `index.lifecycle.origination_date` setting was set. This had the disadvantage of the user not being able to update the `origination_date` anymore once set. This commit changes the way we makes use of the `index.lifecycle.origination_date` setting by checking its value when we calculate the index age (ie. at "read time") and, in case it's not set, default to the index creation date. * Make origination date setting index scope dynamic * Document orignation date setting in ilm settings (cherry picked from commit d5bd2bb77ee28c1978ab6679f941d7c02e389d32) Signed-off-by: Andrei Dan <andrei.dan@elastic.co> |
