> > I can't find a mechanism that would allow changing the column type from eg STRING to BYTES during aggregation > > This prompts me to think the real problem to solve is to allow `agg(CAST(strCol AS BYTES))`, can I assume this change in ingestion is no longer needed if we have support for the above? To clarify, I meant during rollup aggregations, where we turn multiple rows into 1, because sketches are usually used to compact rows It is still desirable to create sketches during ingestion because it reduces the size of data stored in Pinot and removes the requirement to preprocess data to create sketches and roll it up before pushing to Pinot -- This is an automated message from the Apache Git Service.
