Hey all,
I have a patch that allows you to specify Erlang funs as strings for
use in map/reduce via both the REST and protocol buffer APIs. So you
can do things like:
## For REST
{"reduce":{"language":"erlang",
"source":"
fun(ValueList, _Arg) ->
[lists:foldl(fun erlang:'+'/2, 0, ValueList)]
end.",
"keep":true}}
## For pb
Mapper = "fun(G, _X, _Y) ->
O = riak_object:get_value(G),
[proplists:get_value(blah, O)]
end.".
riakc_pb_socket:mapred(Pid, Input, [{map, {strfun, Mapper}, unset, true}]).
I posted a note about this to the list a month ago, but haven't
received any response. Curious if this is of interest to other users.
Basho team, comments?
