DB2 FOR LUW / DB2FORLUW / A10 - DB2

Query performance may be poor in a Federated DPF environment for 
queries involving the LATERAL keyword in the statement text. 
 
Affected queries would typically contain the LATERAL keyword for 
a sub-select of the query, an ORDER BY clause within the 
subselect along with predicates containing references to outer 
sub-selects, tables or nicknames from the query. 
 
The output from db2exfmt will typically show a FILTER operation 
above the SHIP operations containing the correlated predicate.
