Another "but" here is what [0] may happen if you're storing personal data in big indexes... TLDR; In some cases, what data you actually have (as in "on disk") becomes complicated. For instance, in some cases, once a segment reaches max size (5GB by default) it will only be eligible for merging when it accumulates 50% deletions. This means you might not be able to guarantee deletion of data within 30 days (in accordance with the GDPR).
