A subset of log entries is applied to the snapshot, the applying modifying the snapshot to result in a modified snapshot. An access of the first computing node to the data of the database is preserved. Responsive to receiving a signal of activity from the first computing node during the applying and after a grace period has elapsed, the applying is aborted such that the first computing node can continue serving the database in the cluster.
