JMH Benchmarks for RocksJava

These are micro-benchmarks for RocksJava functionality, using JMH (Java Microbenchmark Harness).

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

$ 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

$ mvn package

Running

$ 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.
