thanks @AlexanderSaydakov, I was able to get that working easily. Now I'm just wondering why these base64 strings are able to be read despite the underlying query not running to completion. maybe the object is becoming corrupted within the druid broker code before it is sent off to the sketches library? I've narrowed this down a bit as far as what will trip it.. ~~thetaSketch aggregations that are not a part of filtered aggregations seem to be working fine (the above query with filters removed works just fine). it is when I introduce the filter when the invalid seed issue comes up.~~ I now realize I am only tripping it if the query turns into multiple query fragments. If I target a single data node, I do not hit this issue. But once I have a query that uses a sketch where multiple upgraded data nodes are involved, we seem to run into this. If a query hits two data nodes but one is druid 15 and the other is druid 18, the query will run. I'll have to dive in further on that tomorrow. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
