I am runing this qry on a 500gb table but this seems to be using 4TB of spool space, wanted to check whats wrong
SyntaxEditor Code Snippet
FROM RevDGT.NumFrqnce ro
QUALIFY COUNT ( * ) OVER ( PARTITION BYro.ssn, ro.ssn_inrc.rev_num ,
ro.revnum_et , ro.cd_value ) > 1;
Perhaps one or more of your PARTITION BY columns is a VARCHAR with a large max length - variable length columns are expanded to the max length in spool for sorting.
Or your table may have Block-Level Compression applied while the spool does not.
