Sounds like you want Trino to read Druid segment files directly. I am not aware if such an integration exists but the Trino channels would be a good place to ask. It is certainly technically possible for something like this to exist... the Druid segment reader code is all open source (you know, as part of Druid), but I am not sure if anyone put it together yet. If that does exist (or you make it) please update the thread!
