IT:AD:ArangoDB

ACiD:

• Advantages:
  • Free
  • http://www.tldrlegal.com/license/apache-license-2.0-(apache-2.0)
  • Takes up less space than MongoDB, IT:AD:CouchDB
    • Comparison info: https://www.arangodb.org/2012/11/13/comparing-arangodb-with-mongodb-and-couchdb
• Considerations:
  • Their faq recommends that it not be used for Very Large (Cassandra sized) terabyte scenarios.
  • Not clear on their strategy for UserAgent access to Services (pass-thru routing or Foxx?)
  • Schema-free schemas with shapes: Inherent structures at hand are automatically recognized and subsequently optimized.
  • Querying: ArangoDB is able to accomplish complex operations on the provided data (query-by-example and query-language).
  • Application Server: ArangoDB is able to act as application server on Javascript-devised routines.
  • Mostly memory/durability: ArangoDB is memory-based including frequent file system synchronizing.
  • AppendOnly/MVCC: Updates generate new versions of a document; automatic garbage collection.
  • ArangoDB is multi-threaded.
  • No indices on file: Only raw data is written on hard disk.
  • ArangoDB supports single nodes and small, homogenous clusters with zero administration.
• Disadvantages:
  • Trivial: their SVG graph viewer needs love.
