Exploring Graphs with Elixir

Trying Out the Bolt Driver

Before we get down to the nitty-gritty of querying graphs, let’s look at some raw Bolt.Sips responses to gain some familiarity with how graph data is shipped across our comms channel—the Bolt connection.

Let’s first take a quick peek at the %Bolt.Sips.Response{} struct to get a feel for how this is structured and what kinds of data fields are supported:

iex> %Bolt.Sips.Response{}
%Bolt.Sips.Response{
  bookmark: nil,
  fields: nil,
  notifications: [],
  plan: nil,
  profile: nil,
  records: [],
  results: [],
  stats: [],
  type: nil
}

For now, we are going to be mainly looking at the results and stats fields, and later we’ll use the type field as a means to select between the two.

We’ll keep things simple ...
