Loading stuff into neo via the batch API

neo_loading.rb

# So the problem is inserting data into neo using the batch API. So we have a bunch of people and we want to put them into the graph and also
# add to to the index so that we can search for them. 
# The way the batch API works is that you can refer to previous commands by referencing their index in the list of commands (zero indexed)
# e.g. if I want to reference the person added in the first command I would reference that node as {0} 
# You should be able to see how that works in the code below.  

neo_people_to_load = Set.new
neo_people_to_load << { :name => "Mark Needham", :id => 1 }
neo_people_to_load << { :name => "Jenn Smith", :id => 2 }
neo_people_to_load << { :name => "Chris Ford", :id => 3 } 

command_index = 0
people_commands = neo_people_to_load.inject([]) do |acc, person| 
  acc << [:create_node, {:id => person[:id], :name => person[:name]}]
  acc << [:add_node_to_index, "people", "name", person[:name], "{#{command_index}}"]
  command_index += 2
  acc
end

# So what we want to get is the following:
# [
#  [:create_node, {:id=>"1", :name=>"Mark Needham"}], [:add_node_to_index, "people", "name", "Mark Needham", "{0}"], 
#  [:create_node, {:id=>"2", :name=>"Jenn Smith"}], [:add_node_to_index, "people", "name", "Jenn Smith", "{2}"], 
#  [:create_node, {:id=>"3", :name=>"Chris Ford"}, [:add_node_to_index, "people", "name", "Chris Ford", "{4}"]
# ]
