Cache:

|
Assume you want to configure stuff one host ("monitor node"),
|
|
|
|
|
depending on the configuration of other hosts ("cluster nodes").
|
|
|
|
|
|
|
|
|
|
For instance, the monitor host would like to know,
|
|
|
|
|
which hosts are configured with the provider
|
|
|
|
|
"apache" and option --start true.
|
|
|
|
|
|
|
|
|
|
This requires the monitor node to be able to
|
|
|
|
|
query all other configured nodes. It can't
|
|
|
|
|
ask for all hosts, because cdist does not
|
|
|
|
|
know which hosts are configured or may exist.
|
|
|
|
|
|
|
|
|
|
Example implementation
|
|
|
|
|
|
|
|
|
|
If cdist keeps ("caches") the configuration of every
|
|
|
|
|
node it configures, each new node can query the
|
|
|
|
|
cache for existing nodes that acquired the given
|
|
|
|
|
configuration.
