findPagedRows()
Same as the previous one but takes paging into account.
CassandraAlertDao.java:
@Override
protected <M> MarkPage<String> findPagedRows(CassandraAlertFilter filter,
SortSpecification<CassandraAlertSortAttribute> sort,
final MarkPageRequest<M> pageRequest,
final DataStoreContext context) {
if (filter == null) {
if (pageRequest == null) {
throw new RuntimeException("Page request cannot be null");
