If I understand it correctly, What about writing one Hiera backend . This should be "easy", and you will leverage all the hiera puppet support and compatibility.
You could write a redis or riak hiera backend. I don't, think writing this using postgres or mysql would scale at least for writes. But writes are much less frequent than writes in this use case. Puppetdb does some magic to make the lowest writes as possible to the database. http://docs.puppetlabs.com/hiera/1/custom_backends.html Examples https://github.com/reliantsecurity/hiera-redis/blob/master/README.md http://beingasysadmin.wordpress.com/2012/11/24/hiera-http-and-riak/ https://github.com/garethr/hiera-etcd/blob/master/README.md Best lmello Em 15/09/2014 20:34, "Trevor Vaughan" <tvaug...@onyxpoint.com> escreveu: > I'm actually looking for a way to add dynamically created data items to a > common data store for multiple clustered puppet masters. > > Various Ideas: > > Redis or Riak: One per Puppet Master > Pros: Fast and probably redundant enough > Cons: Possibly not atomic enough and adds a lot of complexity > > Clustered MySQL or PostgreSQL: One per PM > Pros: Atomic and reliable > Cons: Complex > > Multi-Master LDAP > Pros: Atomic, fast reads > Cons: Not really all that many but why do this when we're already > sitting on a Postgres solution that will need to scale in the future anyway. > > But wait!
