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.
