Highlights

Version 3.3

Datacenter to Datacenter Replication: Replicatethe entire structure and content of an ArangoDB cluster asynchronously toanother cluster in a different datacenter with ArangoSync. Multi-datacentersupport means you can fallback to a replica of your cluster in case of adisaster in one datacenter.
Encrypted Backups:Arangodump can create backups encrypted with a secret key using AES256block cipher.

Server-level Replication:In addition to per-database replication, there is now an additionalglobalApplier. Start the global replication on the slave once and allcurrent and future databases will be replicated from the master to theslave automatically.
Asynchronous Failover:Make a single server instance resilient with a second server instance, oneas master and the other as asynchronously replicating slave, with automaticfailover to the slave if the master goes down.

RocksDB Storage Engine: You can now useas much data in ArangoDB as you can fit on your disk. Plus, you can enjoyperformance boosts on writes by having only document-level locks
Pregel:We implemented distributed graph processing with Pregel to discover hiddenpatterns, identify communities and perform in-depth analytics of large graphdata sets.
Fault-Tolerant Foxx: The Foxx managementinternals have been rewritten from the ground up to make suremulti-coordinator cluster setups always keep their services in sync andnew coordinators are fully initialized even when all existing coordinatorsare unavailable.
Enterprise: Working with some of our largest customers, we’ve addedfurther security and scalability features to ArangoDB Enterprise likeLDAP integration,Encryption at Rest, and the brand newSatellite Collections.

SmartGraphs: Scale with graphs to acluster and stay performant. With SmartGraphs you can use the “smartness”of your application layer to shard your graph efficiently to your machinesand let traversals run locally.
Encryption Control: Choose your level of SSL encryption
Auditing: Keep a detailed logof all the important things that happened in ArangoDB.
