AWS基于Mysql/postgres开发的Aurora，是个很热门的OLTP数据库产品。目前很多用户很关心Aurora。
更多关于Aurora的介绍，请参考官方文档：
https://docs.aws.amazon.com/zh_cn/AmazonRDS/latest/AuroraUserGuide/CHAP_AuroraOverview.html
各种官方的性能测试，也充分展示了Aurora的强劲实力。
闲来无事，通过sybench，测试一下Aurora Mysql和RDS原生Mysql之间性能差异。测试结果仅供参考。
网络上比较流行的一张性能对比图，越大的机型，性能aurora的性能优势体现的越好。
测试环境准备，由于Aurora目前只有中国宁夏区有提供服务，所以测试环境都是基于宁夏Region测试的。
<1. EC2 m4.xlarge （4CPU 16G）
<2. RDS db.r4.xlarge （4 vCPU 30.5 GiB ） Mysql版本5.7.12
<3. Aurora db.r4.xlarge （4 vCPU 30.5 GiB ） Mysql版本5.7.12
<4. 为了减少网络因素的影响，将这些机器，都放置在同一个AZ。
<5. EC2 选择 Amazon AMI2，并安装sysbench 1.0.17
<6. Mysql创建20个表，每个表1000W行数据，数据量在40G左右（避免数据全部cache到内存中，而测试不到IO的性能影响）。
<7. 还另外插入20表，100W行/表，做插入时间比对。
1. 数据库中插入20个表，每个表100W行数据，看插入时间比较。Mysql 耗时 5m32.238s，Aurora耗时7m28.073s。

2. Aurora的链接方式，以及replica的的只读访问的连接分配
Aurora直接连接点个数据库节点的Endpoint方式
mysql -hmyaurora.cq7qaukj3smd.rds.cn-northwest-1.amazonaws.com.cn \ -uadmin -padmin123 -e "create database dbtest1;"
Aurora通过Cluster Endpoint进行连接
连接到主库，进行写入和读取操作
cluster-aurora.cluster-cq7qaukj3smd.rds.cn-northwest-1.amazonaws.com.cn
连接到replica 数据库，进行只读操作，会自动分配连接到不同的可用slave上
cluster-aurora.cluster-ro-cq7qaukj3smd.rds.cn-northwest-1.amazonaws.com.cn
多次并行发起查询测试，可以看到，连接会到不同的slave节点上，这点也是Aurora的优点，大并发的读操作，会比传统的Mysql更有优势。

4. AWS官方blog也有测试输出，Aurora的性能比Mysql好不少。具体可以参考。
https://amazonaws-china.com/cn/blogs/china/aurora-test/?nc1=b_rp
我的测试环境，相对来说，单表更多的行数，也是有一些区别的。
个人感觉，由于Aurora不直接写datafile，只写binlog的方式，势必比Mysql要写datafile快很多。而且在越大数据库，和硬件配置的情况下。IO这部分的影响会越明显。
另外Aurora的多slave读取共享数据文件的情况，也会让slave的数据同步，比传统Mysql slave要更实时。
并且replica slave的cluster域名访问，自动分配查询到不同的slave，也节省从应用层面做load balance更简易。
而且aurora可以结合AWS auto-scaling，做到弹性伸缩。才能真正体会“云”的优势。
当然，以上测试，纯是一个技术吊丝无聊举动，仅供参考。实际情况，可以根据我的方法，调整表的数量，和单表的行数。会更接近实际生产情况。
