尝试配置ArangoDB复制时出错

Question

While trying to configure an async replication on an ArangoDB database (using the document https://docs.arangodb.com/3.3/Manual/Administration/Replication/Asynchronous/Components.html ) I got this error:

JavaScript exception in file 
'/usr/share/arangodb3/js/client/modules/@arangodb/replication.js' at 209,7: 
ArangoError 1470: replication API is not supported on a coordinator
!      throw err;
!      ^
stacktrace: ArangoError: replication API is not supported on a coordinator

Any idea what could have caused it? I'm on the latest 3.3.3 version with a cluster up and running on 3 different machines.

Answer 1

You are accessing a coordinator. The replication API resides only on DB servers in an ArangoDB cluster. You will see a different behavior if you move to DB servers.
