Scalar DB example

A very small simple CLI application to use Scalar DB. This application supports some commands to create a player and make a player attack another player and etc.

Build

$ ./gradlew installDist

Database schema setup

This tool uses schema-loader. Build schema-loader in advance.

$ SCHEMA_LOADER_JAR_PATH=$HOME/src/scalardb/schema-loader/build/libs/scalardb-schema-loader-4.0.0-SNAPSHOT.jar ./setup.sh
