> SQL query on re-indexed columns with double/float/long first and last aggregators WON'T work. This involves some changes in complex type handling which might be better in another PR. What happens when a user issues the `EARLIEST(expr, maxBytesPerString)` function on a longFirst column - do we expect that it will fail? Is the error message in this case clear? I'm asking because it looks like #10332 added handling of complex type columns, which used to be ok because stringFirst/Last was the only type of complex column. But now that we've introduced these column types, the expected behavior is less clear. Perhaps you can add some tests to CalciteQueryTest to validate the behavior that we want users to see when they issue sql queries on these column types. -- This is an automated message from the Apache Git Service.
