I've created a set of functions that exposes the PuppetDB query API

with any bugs or feedback.

They require ruby-restclient, ruby-json and the puppetdb-terminus.
To give you an example of a query you can do inside puppet code using
these functions and PuppetDB:
# Return an array of active nodes with an uptime more than 30 days and
# having the class 'apache'
$hosts = pdbnodequery([ 'and', [ '=', [ 'node', 'active' ], true ],
['>', [ 'fact', 'uptime_days' ], 30 ] ],
[ 'and', [ '=', 'type', 'Class' ], [ '=', 'title', 'Apache' ] ] )"
This can be used for example to populate lists of nodes behind load
balancers and such dynamically instead of writing them down in your
puppet code.
Nice! Do you have any number comparing the performance of this against
collection of a similar amount of resources by the puppetmaster?
