I am trying to use origination\_date with ILM phases and need some help. I am creating the indexes manually of the format shipdetails-2020.08.19. We can create 7 indexes on a given date. Now the events will be stored accordingly based on the date-
shipdetails-2020.08.21
shipdetails-2020.08.22
shipdetails-2020.08.23
shipdetails-2020.08.24
shipdetails-2020.08.25
shipdetails-2020.08.26
shipdetails-2020.08.27
I wanted to implement an ILM based on the origination date (phase transition based on the date math present in the index name).
How can we set upfront index.lifecycle.parse\_origination\_date` to `true` for all the index by matching patterns or do we need to set this property manually during creation of indexes
Please suggest
