Hi @vp096

Is your use case really about deleting data 15 mins old, or are you just testing?

The reason I ask is ILM is not really design to operate on "Minute" Scheduled or Small KB/MB indices is designed to manage large scale indices GB, Hours, Days etc. and for that it works very well.

I posted a bit about it [here](https://discuss.elastic.co/t/rollover-goes-beyond-the-condition/207442/2) and another elastician [here](https://discuss.elastic.co/t/lifecycle-policies-dont-work/276218/13)
