Abstract: Selective application of log records may be performed. A target storage node for a new replica being added to a replica group for a database may obtain a paginated result of a scan of ordered items of the database from a source. The paginated result may have a log sequence number that corresponds to a replica log consistent with the paginated result. The target storage node may obtain log records from the replication log after the log sequence number for the paginated result. The target storage node may selectively apply the log records from the replication log according to one or more application rules that determine whether to ignore a change described in a log record.
