Abstract
A query for data stored in a database that includes a set of segments is received at a computer system. The set of segments are divided into a plurality of columns and at least one column of the plurality of columns includes one or more fields. The system analyzes the query to determine fields required to be retrieved from the database. The system determines whether a required field of the query is located in a main memory of the computer system. The system creates an input/output request for a column containing the required field for a plurality of segments of the set of segments prior to executing the query.
