Abstract
A method and associated systems for a deduplication module of a database-management system. The database-management system, upon receiving a request to perform a transaction that will revise a stored database record, uses memory-resident logs and previously generated database-maintenance tables to: i) identify a first logical block that identifies an updated value, stored in a physical block of storage, to be used to update the database record; and ii) further identify a second logical block that stores in the database a corresponding existing value of the same record. After determining that the first and second logical blocks reside on physical storage devices within the same storage tier, the system directs the deduplication module to associate both logical blocks with the first physical block.
