Hello reader! Welcome, let's start-

BenchBase (formerly OLTPBench) is a Multi-DBMS SQL Benchmarking Framework via JDBC.

To clone and build BenchBase using the postgres profile,

git clone –depth 1
cd benchbase
./mvnw clean package -P postgres
This produces artifacts in the target folder, which can be extracted,

cd target
tar xvzf benchbase-postgres.tgz
cd benchbase-postgres
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:

hyadapt — pending configuration files
Resource Stresser
TPC-DS — pending configuration files

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.)

Usage Guide
How to Build
Run the following command to build the distribution for a given database specified as the profile name (-P). The following profiles are currently supported: postgres, mysql, mariadb, cockroachdb, phoenix and spanner.

./mvnw clean package -P
The following files will be placed in the ./target folder:


How to Run
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:

usage: benchbase
-b,–bench [required] Benchmark class. Currently
supported: [tpcc, tpch, tatp, wikipedia,
resourcestresser, twitter, epinions, ycsb,
seats, auctionmark, chbenchmark, voter,
sibench, noop, smallbank, hyadapt]
-c,–config [required] Workload configuration file
–clear Clear all records in the database for this
–create Initialize the database for this benchmark
-d,–directory Base directory for the result files,
default is current directory
–dialects-export Export benchmark SQL to a dialects file
–execute Execute the benchmark workload
-h,–help Print this help
-im,–interval-monitor Throughput Monitoring Interval in
–load Load data using the benchmark’s data
-s,–sample Sampling window

How to Run with Maven
Instead of first building, packaging and extracting before running benchbase, it is possible to execute benchmarks directly against the source code using Maven. Once you have the project cloned you can run any benchmark from the root project directory using the Maven exec:java goal. For example, the following command executes the tpcc benchmark against postgres:

mvn clean compile exec:java -P postgres -Dexec.args=”-b tpcc -c config/postgres/sample_tpcc_config.xml –create=true –load=true –execute=true”

this is equivalent to the steps above but eliminates the need to first package and then extract the distribution.

How to Enable Logging
To enable logging, e.g., for the PostgreSQL JDBC driver, add the following JVM property when starting…


To modify the logging level you can update and/or

How to Release
./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 17.
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 (
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.
