This option may be set to FAST (the default) to request the checkpoint be completed as fast as possible, or SPREAD to request the checkpoint be spread over a longer interval (based on the checkpoint-related configuration parameters). Note that the server may consolidate the options for concurrently requested checkpoints. For example, if one session requests a "fast" checkpoint and another requests a "spread" checkpoint, the server may perform one "fast" checkpoint.
