> The RocksDB JNI interface {{RocksObject}} has a dispose() function which need
> to be explicitly triggered after it is not reused, otherwise GC may not be
> able to de-reference it off-heap and hence effective lead to memory leak.
> See: https://github.com/facebook/rocksdb/issues/752#issuecomment-146511412
> We need to make sure all library-controlled RocksDB objects are disposed
> after usage, and also indicate users to {{close}} those out-of-control
> objects.
> Note that RocksDB community is also going to replace the {{dispose}} API by
> extending {{AutoClosable}} in the future, so this ticket may need to be
> re-visited when upgrade RocksDB versions:
