# JMH Benchmarks for RocksJava
These are micro-benchmarks for RocksJava functionality, using [JMH (Java Microbenchmark Harness)](https://openjdk.java.net/projects/code-tools/jmh/).
## Compiling
**Note**: This uses a specific build of RocksDB that is set in the `<version>` element of the `dependencies` section of the `pom.xml` file. If you are testing local changes you should build and install a SNAPSHOT version of rocksdbjni, and update the `pom.xml` of rocksdbjni-jmh file to test with this.
For instance, this is how to install the OSX jar you just built for 6.26.0
```bash
$ mvn install:install-file -Dfile=./java/target/rocksdbjni-6.26.0-SNAPSHOT-osx.jar -DgroupId=org.rocksdb -DartifactId=rocksdbjni -Dversion=6.26.0-SNAPSHOT -Dpackaging=jar
```
```bash
$ mvn package
```
## Running
```bash
$ java -jar target/rocksdbjni-jmh-1.0-SNAPSHOT-benchmarks.jar
```
NOTE: you can append `-help` to the command above to see all of the JMH runtime options.
