You can delete all unused columns from lookup.Then lookup
will create cache only on columns in lookup.This will
improve the performance too.

Except the 10 columns, if any other column is not being
used for any matching/filter condition, then remove the
columns from the look up table and the columns which are
used in the filter condition but are not taken forward in
the target, uncheck the oputput port and keep them as Input
port.

hey...i think we can use dynamic lookup too..in dynamic
lookup mark ignore the columns you dont want them tp
participate in lookup process rest for every port specify a
expression for lookup..
