I can't find a way to be sure a document or an index has been rolled-up before removing it.
When using the Rollup API to gain space and get smaller indexes / longer data retention, there is obviously a removing process to engage. But as I understand this is not part of the Rollup features.
So if I configured a Job to Rollup logs older than a month, I should be able to remove raw logs older than a month via DELETE INDEX or Delete By Query. BUT what if the Rollup did not run yet? How can I be sure I'm not deleting documents I did not merge yet?!!
