SELECT node_id, path, piece_num, root_piece_id, durability_ratio, queued_at, requested_at, last_failed_at, last_failed_code, failed_count, finished_at, order_limit_send_count
FROM graceful_exit_transfer_queue
WHERE node_id = '[redacted]'
AND finished_at is NULL
AND last_failed_at is NULL
ORDER BY durability_ratio asc, queued_at asc LIMIT 300 OFFSET 0;
