Our next major release ArangoDB 2.6 is on the finishing straight with an early alpha2 version for Linux released today.

UPDATE: New alpha3 release available.

We put great efforts in speeding-up core ArangoDB functionality to make AQL queries perform much better than in earlier versions of ArangoDB.

The queries that improved most in 2.6 over 2.5 include:

  • FILTER conditions: simple FILTER conditions we’ve tested are 3 to 5 times faster
  • simple joins using the primary index (_key attribute), hash index or skiplist index are 2 to 3.5 times faster
  • sorting on a string attribute is 2.5 to 3 times faster
  • extracting the _key or other top-level attributes from documents is 4 to 5 times faster
  • COLLECT statements: simple COLLECT statements we’ve tested are 7 to 15 times faster
