TPC-C Driver for MySQL Compliant Databases

This driver is forked from github.com/Percona-Lab/tpcc-mysql

Build Binaries

Running make -C src/ will build two binaries: tpcc_load and tpcc_start.

Generate Dataset

The tpcc_load binary can be invoked to generate arbitrarily sized datasets, and can be parallelized in multiple ways. On every invocation, the -w (warehouse count), -m (minimum warehouse # to start generating data for), and -n (warehouse # to stop generating data at) flags must be passed. These can be used to generate only the slices of data that belong to those warehouses. Second, the -l flag can passed to generate data for only a subset of tables; passing no -l flag at all will cause all data types to be generated, while passing 1 - 4 will create the corresponding subset.

While running, the generator will write files to disk in the format {table}.{min warehouse}.{chunk #}. As files reach the size limit (20MB), the completed chunk's filename is written to stderr and the next chunk is begun. This allows scripting parallelized gzip and upload of the pipe separated value files.

Create a database

This repository contains schemas and indices for all tables. A single DDL file with a schema optimized for MemSQL is provided as memsql_create_table.sql, while create_table.sql and add_fkey_idx.sql are for MySQL. If using MemSQL, be sure to tune the replication, durability, and replication settings when you create your database. Run the DDL files against your database (mysql -h 127.0.0.1 ... database < memsql_create_table.sql).

Loading data

The dataset created by the generator is in pipe-separated values format, which can be loaded via LOAD DATA using either MySQL or MemSQL. MemSQL also has functionality for 'pipelines', which will allow you to easily and rapidly load the data from a cloud data store like S3. Documentation is available online: https://docs.memsql.com/memsql-pipelines/v6.7/pipelines-overview/

Run the Benchmark

The tpcc_start binary will run the actual workload against your database. It takes the following flags:

  • -h: host to connect to
  • -P: port to connect to
  • -d: database to connect to
  • -u: user to connect as
  • -p: password to use
  • -w: number of warehouses to run against
  • -r: warmup time (in seconds) before starting to gather results
  • -c: connections to run in parallel
  • -i: interval (in seconds) to report intermittent results
  • -l: duration to run the benchmark for (in seconds)

Output

With the defined interval (-i option), the tool will produce the following output:

  10, trx: 12920, 95%: 9.483, 99%: 18.738, max_rt: 213.169, 12919|98.778, 1292|101.096, 1293|443.955, 1293|670.842
  20, trx: 12666, 95%: 7.074, 99%: 15.578, max_rt: 53.733, 12668|50.420, 1267|35.846, 1266|58.292, 1267|37.421
  30, trx: 13269, 95%: 6.806, 99%: 13.126, max_rt: 41.425, 13267|27.968, 1327|32.242, 1327|40.529, 1327|29.580
  40, trx: 12721, 95%: 7.265, 99%: 15.223, max_rt: 60.368, 12721|42.837, 1271|34.567, 1272|64.284, 1272|22.947
  50, trx: 12573, 95%: 7.185, 99%: 14.624, max_rt: 48.607, 12573|45.345, 1258|41.104, 1258|54.022, 1257|26.626

Where:

  • 10 - the seconds from the start of the benchmark
  • trx: 12920 - New Order transactions executed during the gived interval (in this case, for the previous 10 sec). Basically this is the throughput per interval. The more the better
  • 95%: 9.483: - The 95% Response time of New Order transactions per given interval. In this case it is 9.483 sec
  • 99%: 18.738: - The 99% Response time of New Order transactions per given interval. In this case it is 18.738 sec
  • max_rt: 213.169: - The Max Response time of New Order transactions per given interval. In this case it is 213.169 sec
  • the rest: 12919|98.778, 1292|101.096, 1293|443.955, 1293|670.842 is throughput and max response time for the other kind of transactions and can be ignored
You can’t perform that action at this time.
