Shulou(Shulou.com)06/01 Report--

High availability is the most important aspect of system architecture for many database engineers / architects. On AWS, Multi-AZ is a very important HA scheme for RDS.

However, whether enabling Multi-AZ has an impact on system performance and how much performance is sacrificed is the point of many user relations.

Today, I'm going to test the performance of Multi-AZ.

1. Environmental preparation

Create the EC2 of m4.xlarge (4CPU 16G) in the same AZ as RDS Mysql, which can reduce the influence of network factors.

Create a RDS Mysql for db.m4.xlarge (4CPU 16G)

two。 The method of installing sysbench based on RDS AMI2

Https://github.com/akopytov/sysbench this is the address of sysbench on git, which contains installation tutorials, including centoscurl-s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bashsudo yum-y install sysbench

3. Sysbench data generation, generate sbtest table under sbtest library, a total of 100W records.

# sysbench-test=oltp-- oltp-table-size=1000000-- oltp-read-only=off-- init-rng=on-- num-threads=16-- max-requests=0-- oltp-dist-type=uniform-- max-time=1800-- mysql-user=root-- mysql-socket=/tmp/mysql.sock-- mysql-password=123456-- db-driver=mysql-- mysql-table-engine=innodb-- oltp-test-mode=complex prepare

For more uses of sysbench, please refer to another blog article

Https://blog.51cto.com/hsbxxl/2068181

4. The EC2 machine needs to install mysql client to prepare to connect to the database

Download address for RHEL7 series mysql5.7:

Rpm-ivh http://repo.mysql.com/mysql57-community-release-el7-11.noarch.rpmyum install mysql-community-client-y

5. Connect to the database

Mysql-hbjs.cbchwkqr6lfg.rds.cn-north-1.amazonaws.com.cn-uadmin-padmin123

6. Create a test database:

Mysql > create database dbtest

7. Insert data

Create 20 test tables

1 million rows of data per table.

# time sysbench/ usr/share/sysbench/tests/include/oltp_legacy/oltp.lua\-mysql-host=bjs.cbchwkqr6lfg.rds.cn-north-1.amazonaws.com.cn-- mysql-port=3306-- mysql-user=admin-- mysql-password=admin123\-- mysql-db=dbtest-- oltp-tables-count=20-- oltp-table-size=1000000\-- report-interval=10-- rand-init=on-- max-requests=0\-- oltp-read-only=off-- time=120-- threads=30\ prepare

Query the entire mysql database size, prepare 50 gigabytes of data, and prepare for testing

Mysql > select concat (round (sum (data_length/1024/1024), 2), 'MB') as data from information_schema.tables;+-+ | data | +-+ | 50100.26MB | +-+ 1 row in set (0.03 sec)

In fact, after I created multiple libraries by executing sysbench many times, I accumulated the data to 50 gigabytes, but during the test, there was only 4.2 gigabytes.

Mysql > select concat (round (sum (data_length/1024/1024), 2), 'MB') as data from information_schema.tables where TABLE_SCHEMA='test';+-+ | data | +-+ | 4267.05MB | +-+ 1 row in set (0.00 sec)

8. Prepare for the test and test the concurrency of 30, 50, 100, 200, 800, 1000, respectively

Time sysbench/ usr/share/sysbench/tests/include/oltp_legacy/oltp.lua\-mysql-host=bjs.cbchwkqr6lfg.rds.cn-north-1.amazonaws.com.cn-- mysql-port=3306-- mysql-user=admin-- mysql-password=admin123\-- mysql-db=test-- oltp-tables-count=20-- oltp-table-size=1000000\-- report-interval=10-- rand-init=on-- max-requests=0\-- oltp-read-only=off-- time=120-- threads=100\ run

9. The test results are as follows

Single-AZ

Multi-AZ
