### Before submit

- [X] 我已经确认现有的 [Issues](https://github.com/apache/hugegraph/issues) 与 [FAQ](https://hugegraph.apache.org/docs/guides/faq/) 中没有相同 / 重复问题 (I have confirmed and searched that there are no similar problems in the historical issue and documents)

### Environment (环境信息)

- Server Version: 1.0.0 (Apache Release Version)
- Backend: RocksDB x nodes, HDD or SSD
- OS: xx CPUs, xx G RAM, Ubuntu 2x.x / CentOS 7.x
- Data Size: xx vertices, xx edges

### Expected & Actual behavior (期望与实际表现)

请问当hugegraph存储是memory时，存的数据量是不是有限制，我同步了100w多条边，但通过hubble的g.E().count()查看边却只有2w条

### Vertex/Edge example (问题点 / 边数据举例)

### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构)
