I have a question regarding historicals. Is it always necessary to load all segments into druid historicals in order to query their data? I'm particulary interested in using historicals in a LRU-like fashion, where required segments are pulled from deep storage on demand and the least used segments are dropped to make space for required ones. I'm aware of DeepStorage queries but would prefer "warmed up" historicals instead (so that there might be a one-time cost for loading the segments but subsequent more detailed queries would be fast). I couldn't find any mention of such feature or setting in the documentation. Any help would be very appreciated 😄

This is currently not possible.

Thanks for the Info 👍
