Documentation
Definition
The number of requests issued by the group buffer pool structure owner for group buffer pool checkpoints to read the directory entries of all changed pages in the group buffer pool, so that the oldest recovery log record sequence number (LRSN) can be recorded and used for recovery purposes in case the group buffer pool fails.
Such requests might have to be issued several times for each group buffer pool checkpoint in order to read the directory entries for all changed pages.
