AWS RDS PIOPS瓶颈 [英] AWS RDS PIOPS bottlenecked

问题描述

我正在运行以下rds实例.但是，我的写入PIOPS处于分配的PIOPS的20％的瓶颈.

I'm running the following rds instance. However, my write PIOPS is bottlenecked at 20% of the allocated PIOPS.

db.r3.xlarge
Provisioned IOPS (SSD)
5000 PIOPS
600 GB

您有任何想法为何将其卡在其中吗?

Do you have any ideas why it's stuck there?

谢谢.

推荐答案

您的RDS实例类型I/O受两个因素限制. IOPS和吞吐量.由于您没有达到IOPS限制，因此吞吐量可能会卡在这里.

Your RDS instance type I/O are limited by two factors. IOPS and throughput. As you don't reach your IOPS limit it's probably your throughput which stuck here.

您有一个非常有趣的文档此处.

You have a very interesting piece of documentation here.

您可以尝试从r3.xlarge升级到r3.2xlarge来测试吞吐量需求并进行相应的更新.

You could try to upgrade from r3.xlarge to r3.2xlarge to test your throughput needs and update accordingly.
