I tried it with `mta_tax` which has 385 distinct values, and it also crashes. But I'd expect that, seeing as the data isn't already partitioned on that variable and it'd need to all be in memory to work out how many distinct partitions it needs. Actually, no, perhaps I wouldn't given we can call `distinct()` on a column without having all data in memory, though I don't know if the same mechanism that allows that is used when working out what data goes in what partition. But, I don't know how this works internally here. -- This is an automated message from the Apache Git Service.
