The Perils of CouchDB / Postgres to the rescue

CouchDB as an application database kind of sucks. Basically the only reason to use it is because it easily supports unstructured data. Even so, its limitations have a ton of negative ripple effects on basically the entire development process.

Luckily, Postgres has an hstore column type and has recently added a json column type. json supports arbitrary JSON but is stored as text so operations are slower. hstore stores only a flat mapping of string keys and values in a fast binary format, but nesting is on tap for 9.4 (Q3 2014) and non-string types are on the roadmap. In the meantime, nesting can be simulated by storing the full path to a value as the string key, and types can be handled in the application layer including with a query building abstraction that automatically casts hstore values to their expected types in database queries.

Postgres supports a number of other features that all together make it look like a great solution for scalably storing m

getting started with salt

a little adventurous tale of setting up salt on osx...

salt osx docs: http://goo.gl/E6ZtA

overall, seemed pretty straight forward...(?)

  • preliminary steps:
    • brew update (I did this to make sure I was up to date)
    • brew upgrade (I did this to upgrade what I was not up to date with)
  • brew doctor (I did this to make sure I was 'raring to brew')
