Abstract

Provided are techniques for locating a row. A page filter in a page is stored, wherein the page filter is associated with a collision chain and includes a portion of a hash value of the row in the collision chain that has overflowed to an overflow area. In response to a request to locate a target row, the page filter is used to determine that the row has overflowed based on a portion of a hash value of the target row matching the portion of the hash value of the row that has overflowed.
