Defining a ILM policy solely based on size requirements

Elastic Stack Elasticsearch
1

I'm running a cluster on Elastic Cloud and would like to define an ILM policy based on the amount of space I have available on my space.

Currently, when setting up an ILM policy, we have to chose size AND days. I'd like to be able to have the policy done solely on size.

Is that possible?

It's not currently possible. There is an issue open for it however: https://github.com/elastic/elasticsearch/issues/47764
