Schema Registry for BigQuery

Olay Ufku is a schema registry for BigQuery.

Installation & Running

You need Erlang & Elixir installed on your system. Minimal Erlang/OTP version should be 18.0.0. Minimal Elixir version should be 1.4 or greater. You can install Elixir via:

$ brew install elixir

After installing Elixir you need to update hex package management:

$ mix local.hex

After that you need to fetch Phoenix framework tooling:

$ mix archive.install https://github.com/phoenixframework/archives/raw/master/phx_new.ez

Fetch the dependencies inside the directory:

$ mix deps.get

Export related environment variables:

$ export SECRET_KEY_BASE=SomeStringThatIsLong # Optional
$ export GCP_PROJECT=gcp-project-id
$ export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json

Run the server:

$ mix phx.server

Now you can visit localhost:4000 from your browser.

What does "Olay Ufku" means?

"Olay Ufku" is Turkish translation of term "Event Horizon" which ain't a direct borrow from Quantum Mechanics but Ray Kurzweil's Singularity definition.

To me, the concept of the Singularity as a “wall” implies a period of infinite change, that is, a mathematical Singularity. If there is a point in time in which change is infinite, then there is an inherent barrier in looking beyond this point in time. It becomes as impenetrable as the event horizon of a black hole in space, in which the density of matter and energy is infinite.

– Ray Kurzweil

compilation errors

Hello, this looks like an interesting project. There is definitely a need for a bigquery schema registry. I wanted to check it out, but I cannot get passed the 1st step! I'm on a mac and installed elixir with brew.

elixir -v
Erlang/OTP 21 [erts-10.3.2] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe] [dtrace]

Elixir 1.8.1 (compiled with Erlang/OTP 21)

I should say that I have absolutely no erlang experience:

mix local.hex
** (FunctionClauseError) no function clause matching in IO.chardata_to_string/1

    The following arguments were given to IO.chardata_to_string/1:

        # 1
        nil

    Attempted function clauses (showing 2 out of 2):

        def chardata_to_string(string) when is_binary(string)
        def chardata_to_string(list) when is_list(list)

I'm probably missing something and I am looking for pointers. Thanks!
