TPCC benchmark

This is a fork of OLTPBench that is used to run the TPCC benchmark. All the other benchmarks have been removed.

Just like the original benchmark this is a multi-threaded load generator. The framework is designed to be able to produce variable rate, variable mixture load against any JDBC-enabled relational database. The framework also provides data collection features, e.g., per-transaction-type latency and throughput logs.

Dependencies

• Java (+1.7)
• Apache Ant

Environment Setup

• Install Java, Ant and Ivy.
• Download the source code.

  git clone https://github.com/yugabyte/tpcc.git
  

• Run the following commands to build:

  ant bootstrap
  ant resolve
  ant build
  

Setup of the Database

The DB connection details should be as follows:

<!-- config/sample_tpcc_config.xml -->
    <!-- Connection details -->
    <dbtype>postgres</dbtype>
    <driver>org.postgresql.Driver</driver>
    <DBUrl>jdbc:postgresql://<ip>:5433/yugabyte</DBUrl>
    <username>yugabyte</username>
    <password></password>
    <isolation>TRANSACTION_REPEATABLE_READ</isolation>

The details of the workloads have already been populated in the sample config present in /config. The workload descriptor works the same way as it does in the upstream branch and details can be found in the on-line documentation.

Running the Benchmark

A utility script (./tpccbenchmark) is provided for running the benchmark. The options are

-c,--config <arg>            [required] Workload configuration file
   --clear <arg>             Clear all records in the database for this
                             benchmark
   --create <arg>            Initialize the database for this benchmark
   --execute <arg>           Execute the benchmark workload
-h,--help                    Print this help
   --histograms              Print txn histograms
   --load <arg>              Load data using the benchmark's data loader
-o,--output <arg>            Output file (default System.out)
   --runscript <arg>         Run an SQL script
-s,--sample <arg>            Sampling window
-v,--verbose                 Display Messages

Example

The following commands initialize a tpcc database (--create=true --load=true) and a then run a workload (--execute=true) as described in config/workload_all.xml file. The results (latency, throughput) are summarized and written to stdout:

./tpccbenchmark -c config/workload_all.xml --create=true
./tpccbenchmark -c config/workload_all.xml --load=true
./tpccbenchmark -c config/workload_all.xml --execute=true
