You can execute the following statement to check if the RPC execution count is balanced in a distributed plan:
obclient> SELECT/*+ PARALLEL(15)*/t2.zone, t1.svr_ip, COUNT(*) AS RPC_COUNT,
AVG(t1.elapsed_time),AVG(t1.queue_time)
FROM oceanbase.GV$OB_SQL_AUDIT t1, __all_server t2
WHERE t1.svr_ip = t2.svr_ip AND IS_EXECUTOR_RPC = 1
AND tenant_id = 1001
AND request_time > (time_to_usec(now()) - 1000000)
AND request_time < time_to_usec(now())
GROUP BY t1.svr_ip ORDER BY t2.zone;
