Abstract:
Embodiments of the present invention disclose a method, a computer program product, and a computer system for suspending and activating a database index. A computer determines a quantity of changes for a number of rows of a database that are to be made by an update of the database. The computer determines whether to suspend an index of the database based, at least in part, on a comparison between the quantity of changes and a pre-determined threshold value. The computer suspends the index of the database based on a result of the comparison that indicates the quantity of changes at least meet the pre-determined threshold value. A suspension of the index of the database initiates a rebuilding of the index.
