Abstract
A system and method are disclosed for improving the efficiency of write operations by intelligently managing disk pages that are written during checkpoint operations so that write operations can occur with reduced numbers of writes. As write data is received and cached, for example, by a database application, disk pages are allocated to the write data. When a checkpoint operation is taken to write the data cache to disk as modifications or additions to the database file, an intelligent write management module re-assesses the disk page allocation and re-maps disk writes to improve the efficiency of disk input/output (I/O) operations. As such, significant improvements in the speed and efficiency of database operations during checkpoint events are achieved.
