Hi - I've noticed the index size when moved from hot to warm phase doubles up before shrinking in size. Just curious to know if this is the expected behavior and if there is a way to avoid the doubling up part of that from happening? We have sized our key to 300GB in size (3 shards, 1 replica). And…

Yes it's expected, Shrink index API | Elasticsearch Reference [7.11] | Elastic describes it a little more.
