And the functions that i have made are

get_bucket_keys(Bucket) ->
{ok, Pid} = riakc_pb_socket:start_link("127.0.0.1", 8087),
{ok, List} = riakc_pb_socket:list_keys(Pid, Bucket,infinity),
riakc_pb_socket:stop(Pid),
{ok,lists:foldr(fun(Key, Acc) ->
[binary_to_list(Key)|Acc]
end, [], List)}.
%% select the Key and get the values to return
select(DB, Key, Values_to_return) ->
{ok, Pid} = riakc_pb_socket:start_link("127.0.0.1", 8087),
Ret =
case riakc_pb_socket:get(Pid, list_to_binary(DB),
list_to_binary(Key)) of
{ok, FromDBObject} ->
Val = to_list(binary_to_term(riakc_obj:get_value(FromDBObject))),
riakc_pb_socket:stop(Pid),
Return =
lists:foldr(
fun(Key_for_return, Acc)->
case proplists:get_value(Key_for_return, Val) of
undefined -> Acc;
Sth -> [{Key_for_return,Sth} | Acc]
end
end, [], Values_to_return),
{ok, Return};
{error, Msg} ->
{error, Msg}
end,
Ret.
And I do the following to get all the keys in the bucket and then find some
field from that key and return the value.
{ok, Key_list} = db_api:get_bucket_keys("Games"),
lists:foldl(
fun(Key, Acc) ->
case db_api:select("Games", Key, ["game_name"]) of
{ok, []} ->
Acc;
{ok, List} -> [[{"game_id", Key} | List]|Acc]
end
end,[], Key_list).
It works for like around 2-3 seconds then it starts to timeout and
eventually crash..
