1. RocksDB 插件式存儲引擎的優點： 

 

• 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 分佈式圖形處理，您可使用已有的不少著名的圖形算法：

• PageRank

• Weakly Connected Components

• Strongly Connected Components

• HITS (hubs and authorities)

• Single-Source Shortest Path

• Community Detection via Label Propagation

• Vertex Centrality measure

3. 容錯機制的 Foxx: 很是可愛的小狐狸 ：）

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.

new fully documented REST API for managing Foxx services

 

4.  Geo_cursor:

Get documents sorted by the distance to a certain point in space. You can also apply filters and limits to geo_cursor.

 

5.  Arango 數據導出：

Export data as JSON, JSONL and even graphs as XGMML for visualization in Cytoscape. You can find details in the Alpha2 release post.

 

6. 企業級版本更高的安全性和可擴展性：

• Enhanced Authorisation with LDAP

• Encryption at Rest

• Satellite Collections ，with SatelliteCollections you can define collections to shard to a cluster and collections to replicate to each machine.  take it for a spin
