Well, partly. As long as Druid doesn't actually create off-heap Memory, it works OK with JDK11. Currently compiling with JDK11 will show errors, but those errors can be ignored as long as they don't create off-heap Memory, which they do not do. This is an issue we will begin addressing soon, we

My understanding was that the Apache Datasketch project was still having issues with Java 11 and direct memory support in their sketch implementation. That would impact Druid's use of datasketches, and possibly Druid's use of direct memory as well. Does anyone know whether the Datasketch issues

I have no objections to dropping support for JDK 8, but why only support JDK 11? What would it take to support JDK 11 and all newer JDKs? There's an analogy with starting and stopping a train. Once you have stopped a train (settled on a particular JDK release for a number of years) starting it is

Removing Druid support for JDK 8 and adding support for JDK 11
