ArangoDB 2.5.1 is available for download.
It mainly adds slow-query log and killing running queries through the Http API and the web-interface.
ArangoDB has an Http interface for retrieving the lists of currently executing AQL queries and the list of slow AQL queries.The added option
--database.slow-query-threshold could be used to change the default AQL slow query threshold value on server start.
Running AQL queries can also be killed on the server. ArangoDB provides a kill facility via an Http interface. To kill a running query, its id (as returned for the query in the list of currently running queries) must be specified. The kill flag of the query will then be set, and the query will be aborted as soon as it reaches a cancellation point.
