Hey, right now the interval needs to be defined on query time and is never dynamically calculated. The main reason is, that for each new document, you probably have to expand the buckets or you have to have a first to predetermine the oldest and youngest date of the dataset, which requires an additional roundtrip across the cluster (also the bucket expansion would need to occur cross cluster, which sounds like quite an performance impact, but I am not an aggregregations expert).
