In this post I'll look at some of our recent work for benchmark enthusiasts: a TPCC-like workload for Sysbench (version 1.0 or later).
Despite being 25 years old, the TPC-C benchmarkcan still provide an interesting intensive workload for a database in my opinion. It runs multi-statement transactions and is write-heavy. We also decided to use Sysbench 1.0, which allows much more flexible LUA scripting that allows us to implement TPCC-like workload.
Pioneer ddj- t1 midi mapping virtual dj download. For a long time, we used the tpcc-mysql (https://github.com/Percona-Lab/tpcc-mysql) tool for performance evaluations of MySQL and Percona Server for MySQL, but we recognize that the tool is far from being intuitive and simple to use. So we hope the adaptation for Sysbench will make it easier to run.
Although we are trying to mimic the TPC-C standard guidance, there are some major variations we decided to introduce.
First, we do not use fully random text fields. These are hard to compress, and we want to be able to evaluate different compression methods in InnoDB and MyRocks.
Second, we allow you to use multiple table sets, compared to the standard one set of nine tables. The reason is that we want to test workloads on multiple tables and to somewhat emulate SaaS environments, where multiple clients share the same database.
So, there is a DISCLAIMER: this benchmark script was not validated and certified by the TPC organization. The results obtained can't be named as TPC-C results, and the results are not comparable with any official TPC-C results: http://www.tpc.org/information/results_spreadsheet.asp
How to run the benchmark:
We tried to make it as easy as possible to run the benchmark. You still need to take the following steps:
- Make sure you have Sysbench 1.0+ properly installed
- Get our scripts, located at https://github.com/Percona-Lab/sysbench-tpcc
- Prepare the dataset
- Run
The command line might look like this:
2 | ./tpcc.lua--mysql-socket=/tmp/mysql.sock--mysql-user=root--mysql-db=sbr--threads=20--tables=10--scale=100--use_fk=0 --mysql_storage_engine=rocksdb--mysql_table_options='COLLATE latin1_bin'--trx_level=RC prepare |
As MyRocks does not support Foreign Keys, so --use_fk=0. also MyRocks in Percona Server for MySQL does not support Repeatable-Read, so we use READ-COMMITTED (--trx_level=RC). MyRocks also requires a binary collation for string fields in indexes (--mysql_table_options='COLLATE latin1_bin').
To run the benchmark, execute:
