The data (parquet) set used in the below query contains 1000 files which only contain a single row with one integer column and 1 large file ~37 MB. The query fails during spilling

alter session set `planner.memory.max_query_memory_per_node` = 37127360;
alter session set `planner.width.max_per_node` = 1;
select count(*) from (select * from small_large_parquet order by col1 desc) d; 
Error: RESOURCE ERROR: External Sort encountered an error while spilling to disk
