A quick run script to get a AWS DynamoDB Local instance going

install_dynamo_db(){
    mkdir -p $1
    curl -L $2 | tar xvz -C $1
}

if [ ! -f ${RUN_DIR}/DynamoDBLocal.jar ]; then
    install_dynamo_db ${RUN_DIR} ${DYNAMODB_LOCAL}
fi
    `which java` -Djava.library.path=${RUN_DIR}/DynamoDBLocal_lib -jar ${RUN_DIR}/DynamoDBLocal.jar ${ARGS}
