How to run a stress test on MySQL?

By using mysqlslap to stress test a server in a non-public environment, you will discover these errors sooner, allowing you to you avoid a database meltdown once your application goes live. This tutorial shows how you can use mysqlslap to run stress tests involving multiple clients, custom queries, different table engines, and much more.

Which is the benchmark tool for MySQL Cluster?

DBT2 Benchmark Tool. The DBT2 Benchmark Tool can be used to run automated benchmarks for MySQL and MySQL Cluster. It supports three types of benchmarks: It has been primarily used on Linux x86_64 platforms, but occasional benchmarks have also been run on Solaris and Windows.

How does the dbt2 benchmark tool work in MySQL?

The transactions are a mix of read and write transactions. Using MySQL the benchmark tests a single MySQL Server instance. Using MySQL Cluster the benchmark tool can drive large distributed tests with many MySQL Cluster Data nodes and MySQL Server instances. The DBT2 Benchmark Tool provides scripts to automate execution of these benchmarks.

How to test MySQL performance on different hardware?

The mysqlslap utility makes it possible to benchmark and compare MySQL performance on different hardware, as well as accurately quantify the effect of a change in database design. This tutorial shows how you can use mysqlslap to run tests involving multiple clients, custom queries, different table engines, and much more.

Who is the creator of SQL query stress simulator?

SQL query stress simulator originally created by Adam Machanic http://sqlblog.com/blogs/adam_machanic/archive/2016/01/04/sqlquerystress-the-source-code.aspx SQLQueryStress is a simple, lightweight performance testing tool, designed to load test individual queries.

What’s the best way to stress test a database?

The defacto standard for comparing one database solution to another is the TPC-C benchmark. The latest definition of this benchmark can be downloaded from http://www.tpc.org/tpcc/default.asp along with existing benchmark result sets.

Which is the best tool to Test SQL queries?

SQLQueryStress is a simple, lightweight performance testing tool, designed to load test individual queries. It includes support for randomization of input parameters in order to test cache repeatability, and includes basic capabilities for reporting on consumed server resources.

What does MySQL 5.1.4 load emulator do?

One of the interesting new tools in MySQL 5.1.4 is mysqlslap, a load emulator that lets you see how well a particular query set or table engine performs under high-load conditions. A query that consumes too many database resources may be the result of designing tables incorrectly, choosing the wrong table type, or creating an inefficient query.

How to force MySQL to run more than once?

You need to adjust MySQL’s ‘max_connections’ variable, which controls the maximum number of concurrent connections allowed by the server. You can force mysqlslap to run a particular test more than once by adding the –iterations switch to the command line. This example runs the same test five times and prints a composite result:

How to analyse MySQL general query log in real time?

I also thought of another approach: turn on genlog; tail -f it and send out the log; periodically truncate the logfile (with “> xxx.log” or “cat /dev/null >xxx.log”). I’m wondering whether it’s practical.

Can you bypass auto generate SQL in MySQL?

While the –auto-generate-sql option is fine for general load testing, you may want to test the performance of a specific query on a database that already exists. In these situations, you can bypass the –auto-generate-sql switch and instead tell mysqlslap to use your own custom query with the –query switch. Here’s the next example:
