Hi Christopher,
thank you for your answer.
Honestly we work with ugameDb and order is next
we start executing code (using C# in Unity3d), it goes to ugame db, than after
ugamedb it goes to Riak(i think ugameDB use RIAK), and after this it sends us
answer.
What code should i send you???
it is first time we are working with ugamedb and riak at all, so we are some
sort of noobs)
here is some code that i’m using in Unity3d (C#)
public IEnumerator eMapQuery()
{
var map = buck.MapReduce(new ErlangMapPhase("unity", "map_phase"), new
ErlangReducePhase("unity", "reduce_phase"));
Debug.Log("Start");
yield return map.WaitUntilDone();
if(map.isSuccessful)
foreach (var item in map.GetResult<Interactor>())
{
Debug.Log("Ok");
foreach (var pair in item.Fields) Debug.Log(pair.Key + " = " +
pair.Value.ToString());
}
else
{
Debug.Log("Fail");
}
}
Erlang code here
>> module(unity).
>> -export([map_phase/3, reduce_phase/2]).
>>
>> map_phase(Value, KeyData, Arg) ->
>> [dict:from_list([{I, 1}
>> || I <- binary_to_term(riak_object:get_value(Value))])].
>>
>>
>> reduce_phase(ValueList, _Arg) ->
>> [lists:foldl(fun(Value, Acc) ->
>> dict:merge(fun(_, X, Y) -> X+Y end,
>> Value, Acc)
>> end,
>> dict:new(),
>> ValueList)].
ugameDB i don’t know it is their own code.
Ildar.
