Hi , Can we ensure LevelDB store uses a JNI driver or not via logging? I have deployed brokers on two CentOS servers, one server with LevelDB installation while the other without installation. After changing the logging level to DEBUG, I still can not find logs to indicate that a JNI driver or a pure java implement is used. On the same server my broker was deployed without LevelDB installation at first, I use a simple load producer to send massive messages to measure performance,after that I installed LevelDB and restarted the broker and the load producer. What make me confused is that the performance measure is very close. So I suspect if the JNI driver is used or not. If not used the java LevelDB will be used?Can I assume the JNI driver always performs better than the java driver?
