To clone and build BenchBase,

git clone --depth 1 https://github.com/cmu-db/benchbase.git
cd benchbase
./mvnw clean package

This produces artifacts in the target folder, which can be extracted,

cd target
tar xvzf benchbase-x-y-z.tgz # Change x-y-z appropriately.
cd benchbase-x-y-z           # Change x-y-z appropriately.

Inside this folder, you can run BenchBase. For example, to execute the tpcc benchmark,

java -jar benchbase.jar -b tpcc -c config/postgres/sample_tpcc_config.xml --create=true --load=true --execute=true

A full list of options can be displayed,

java -jar benchbase.jar -h

Benchmarking is incredibly useful, yet endlessly painful. This benchmark suite is the result of a group of PhDs/post-docs/professors getting together and combining their workloads/frameworks/experiences/efforts. We hope this will save other people's time, and will provide an extensible platform, that can be grown in an open-source fashion.

BenchBase 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.

The BenchBase framework has the following benchmarks:

• AuctionMark
• CH-benCHmark
• Epinions.com
• hyadapt -- pending configuration files
• NoOp
• Resource Stresser
• SEATS
• SIBench
• SmallBank
• TATP
• TPC-C
• TPC-H
• TPC-DS -- pending configuration files
• Twitter
• Voter
• Wikipedia
• YCSB

This framework is design to allow for easy extension. We provide stub code that a contributor can use to include a new benchmark, leveraging all the system features (logging, controlled speed, controlled mixture, etc.)

Run the following command to build the distribution:

./mvnw clean package

The following files will be placed in the ./target folder:

• benchbase-x.y.z.tgz
• benchbase-x.y.z.zip

Once you build and unpack the distribution, you can run benchbase just like any other executable jar. The following examples assume you are running from the root of the expanded .zip or .tgz distribution. If you attempt to run benchbase outside of the distribution structure you may encounter a variety of errors including java.lang.NoClassDefFoundError.

To bring up help contents:

java -jar benchbase.jar -h

To execute the tpcc benchmark:

java -jar benchbase.jar -b tpcc -c config/postgres/sample_tpcc_config.xml --create=true --load=true --execute=true

For composite benchmarks like chbenchmark, which require multiple schemas to be created and loaded, you can provide a comma separated list: `

java -jar benchbase.jar -b tpcc,chbenchmark -c config/postgres/sample_chbenchmark_config.xml --create=true --load=true --execute=true

The following options are provided:

 -im,--interval-monitor <arg>   Throughput Monitoring Interval in
                                milliseconds
    --load <arg>                Load data using the benchmark's data
                                loader
 -s,--sample <arg>              Sampling window

To enable logging, e.g., for the PostgreSQL JDBC driver, add the following JVM property when starting...

-Djava.util.logging.config.file=src/main/resources/logging.properties

To modify the logging level you can update logging.properties and/or log4j.properties.

./mvnw -B release:prepare
./mvnw -B release:perform

BenchBase is the official modernized version of the original OLTPBench.

The original OLTPBench code was largely written by the authors of the original paper, OLTP-Bench: An Extensible Testbed for Benchmarking Relational Databases, D. E. Difallah, A. Pavlo, C. Curino, and P. Cudré-Mauroux. In VLDB 2014. Please see the citation guide below.

A significant portion of the modernization was contributed by Tim Veil @ Cockroach Labs, including but not limited to:

• Built with and for Java 11.
• Migration from Ant to Maven.
  • Reorganized project to fit Maven structure.
  • Removed static lib directory and dependencies.
  • Updated required dependencies and removed unused or unwanted dependencies.
  • Moved all non .java files to standard Maven resources directory.
  • Shipped with Maven Wrapper.
• Improved packaging and versioning.
  • Moved to Calendar Versioning (https://calver.org/).
  • Project is now distributed as a .tgz or .zip with an executable .jar.
  • All code updated to read resources from inside .jar instead of directory.
• Moved from direct dependence on Log4J to SLF4J.
• Reorganized and renamed many files for clarity and consistency.
• Applied countless fixes based on "Static Analysis".
  • JDK migrations (boxing, un-boxing, etc.).
  • Implemented try-with-resources for all java.lang.AutoCloseable instances.
  • Removed calls to printStackTrace() or System.out.println in favor of proper logging.
• Reformatted code and cleaned up imports.
• Removed all calls to assert.
• Removed various forms of dead code and stale configurations.
• Removed calls to commit() during Loader operations.
• Refactored Worker and Loader usage of Connection objects and cleaned up transaction handling.
• Introduced Dependabot to keep Maven dependencies up to date.
• Simplified output flags by removing most of them, generally leaving the reporting functionality enabled by default.
• Provided an alternate Catalog that can be populated directly from the configured Benchmark database. The old catalog was proxied through HSQLDB -- this remains an option for DBMSes that may have incomplete catalog support.
