ArangoDB

ArangoDB is the universal NoSQL database. Never before has it been so easy to setup a NoSQL database on your Mac. No installation of command-line tools required.

ArangoDB Features

• Schema-free schemata: let you combine the space efficiency of MySQL with the performance power of NoSQL.
• Use ArangoDB as an application server and fuse your application and database together for maximal throughput.
• JavaScript for all: no language zoo, you can just use one language from your browser to your back-end.
• ArangoDB is multi-threaded - exploit the power of all your cores.
• Flexible data modelling: model your data as combination of key-value pairs, documents or graphs - perfect for social relations.
• Free index choice: use the correct index for your problem, be it a skip list or geo index.
• Configurable durability: let the application decide if it needs more durability or more performance.
• No-nonsense storage: ArangoDB uses all of the power of modern storage hardware, like SSD and large caches.
• It is Open Source (Apache Licence 2.0)

• UI: added replicationFactor option during SmartGraph creation
• Make the MMFiles compactor perform less writes during normal compaction operation. This partially fixes issue #3144
• Make the MMFiles compactor configurable
• Fix downwards-incompatibility in /_api/explain REST handler
• Fix Windows implementation for fs.getTempPath() to also create a sub-directory as we do on linux
• Fixed a multi-threading issue in cluster-internal communication
• Performance improvements for traversals and edge lookups
• Removed internal memory zone handling code. the memory zones were a leftover from the early ArangoDB days and did not provide any value in the current implementation.
• (Enterprise only) Added `skipInaccessibleCollections` option for AQL queries: if set, AQL queries (especially graph traversals) will treat collections to which a user has no access rights to as if these collections were empty.
• Adjusted scheduler thread handling to start and stop less threads in normal operations
• Leader-follower replication catchup code has been rewritten in C++
• Early stage AQL optimization now also uses the C++ implementations of AQL functions if present. Previously it always referred to the JavaScript implementations and ignored the C++ implementations. This change gives more flexibility to the AQL optimizer.
• ArangoDB tty log output is now colored for log messages with levels FATAL, ERR and WARN.
• Changed the return values of AQL functions `REGEX_TEST` and `REGEX_REPLACE` to `null` when the input regex is invalid. Previous versions of ArangoDB partly returned `false` for invalid regexes and partly `null`.
• Added `--log.role` option for arangod
