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?


Thanks,
SuoNayi
