摘要
A method and system are presented for quantifying a data page repetition pattern for a database index in a database management system. In one embodiment, the method includes identifying a database index to provide a basis for collecting a data page repetition statistic, the database index having a database index key. The method may also include collecting the data page repetition statistic based on the database index key, wherein the data page repetition statistic quantifies a data page repetition pattern associated with database queries that reference sequential entries of the database index. The method may further include optimizing a data page access process based on the data page repetition statistic. In a further embodiment, the method may utilize both cluster ratio and data page repetition statistics to evaluate data page I/O and CPU cost.
