<div dir="ltr">The lists for list partitioned tables are stored as they are specified by the user. While searching for
apartition to route tuple to, we compare it with every list value of every partition. We might do something better
similarto what's been done to range partitions. The list of values for a given partition can be stored in
ascending/descendingsorted order. Thus a binary search can be used to check whether given row's partition key column
hassame value as one in the list. The partitions can then be stored in the ascending/descending order of the
least/greatestvalues of corresponding partitions. We might be able to eliminate search in a given partition if its
lowestvalue is higher than the given value or its higher value is lower than the given value.<br /></div><div
