Adds a new node to ThingsDB. Nodes are used for scaling and high availability.

Before using this command, make sure another node is started and waiting for a join. This can be done by starting thingsdb with the --secret argument, for example:

$ thingsdb --secret "my-one-time-serect"

Next, you will see something like this:

Waiting for an invite from a node to join ThingsDB...

You can use one of the following queries to add this node:

  interface: eth0
    new_node('my-one-time-serect', '', 9220);

Now you can use the new_node(..) function to add the node to ThingsDB.

This function generates an event.


new_node(secret, ip_address [, port]);


Argument Type Description
secret str (required) Secret used to initially connect to the new node.
ip_address str (required) IP Address (IPv4 or IPv6) of the new node.
port int (optional) Node port (listen_node_port), an integer between 0 an 65535, default 9220.

Return value

Returns the new node id if successful.


Add a new node to ThingsDB:

// ThingsDB must be started on node2 using the `--secret ...` argument
new_node('my-one-time-serect', 'node2.local');

Example return value in JSON format (the new node id)
