Node.rack or node.rack_id

Elastic Stack Elasticsearch
1

in the default elasticsearch.yml file I see there is a node.rack
configuration parameter:

# A node can have generic attributes associated with it, which can later
be used
# for customized shard allocation filtering, or allocation awareness. An
attribute
# is a simple key value pair, similar to node.key: value, here is an
example:
#
#node.rack: rack314

but when I read the document there is only a node.rack_id parameter:

http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-cluster.html
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-cluster.html

so , is there any different between them ? or they are just the same ?

It doesn't matter, the value after "node." is just an arbitrary label.
