查看分布式子计划 RPC 执行数是否均衡

运行如下语句可以查看分布式计划 RPC 执行数是否均衡:

obclient>SELECT/*+ PARALLEL(15)*/t2.zone, t1.svr_ip,  COUNT(*) AS RPC_COUNT, 
        AVG(t1.elapsed_time),AVG(t1.queue_time)  
        FROM oceanbase.gv$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;
