1. RocksDB 插件式存储引擎的优势：

• Document-level locks: performance boost for write intensive applications. Writes don’t block reads,and reads don’t block writes

• Support for large datasets: go beyond the limit of main memory and stay performant

• Persistent indexes: faster index build after restart

Check out the step by step guide to compare both storage engines for your use case and OS!

2.Pregel 分布式图形处理，您可以使用已有的很多著名的图形算法：

• PageRank

• Weakly Connected Components

• Strongly Connected Components

• HITS (hubs and authorities)

• Single-Source Shortest Path

• Community Detection via Label Propagation

• Vertex Centrality measure

3.容错机制的Foxx: 非常可爱的小狐狸 ：）

The Foxx management internals has been rewritten from the ground up to make sure multi-coordinator cluster setups always keep their services in sync and new coordinators are fully initialized even when all existing coordinators are unavailable.

5. Arango 数据导出：

6. 企业级版本更高的安全性和可扩展性：
