Configuration
=============

### Requirements

Synchronous replication requires an operational ArangoDB cluster.

### Enabling synchronous replication

Synchronous replication can be enabled per collection. When creating you can specify the number of replicas using *replicationFactor*. The default is `1` which effectively *disables* synchronous replication.

Example:

    127.0.0.1:8530@_system> db._create("test", {"replicationFactor": 3})

Any write operation will require 2 replicas to report success from now on.
