Hi @lsee9, thank you for the report. I would call this a bug of Druid because Druid should have returned a better error than NPE. To answer your questions, I think your assessment is correct about the lack of memory. Please see https://datasketches.apache.org/docs/Quantiles/OrigQuantilesSketch.html for the memory space required per `k`. I'm not sure why the query exploded in your case though because data seems pretty small. What was `druid.processing.buffer.sizeBytes` set to in your test? You could try either with a smaller `k` or a bigger buffer size. -- This is an automated message from the Apache Git Service.
