But if I need to call 2i query from inside of another mapreduce job (from
erlang module), how could I use riakc_pb_socket?

Hi Derek,
The Riak Erlang client (https://github.com/basho/riak-erlang-client) has good
support for mapreduce, so it may be worthwhile switching to this.
Here is an example of how to count records returned by a 2i lookup using a map
reduce query:
riakc_pb_socket:mapred(Pid, {index, <<"bucket"
Note that this uses the luke mapreduce subsystem, which isn't a good
idea as it's been deprecated going forward.
Unfortunately there doesn't seem to be a way that's as simple to do
pipe mapreduce jobs. I'll ping people and see if we can't get you all
some code that's slightly easier to use.

I love this mailing list
Thank you Daniil! I had almost exactly the first thing you recommended, but
the example I found had a slightly different notation, and was throwing
errors that I couldn't figure out.
Your example seems to be working, and I think I can get past my issue
Thanks again

{ok, C} = riak:local_client(),
{ok, Keys} = C:get_index(
Another option, if you want range query:
{ok, C} = riak:local_client(),
{ok, Keys} = C:get_index(<<"bucket_name">>, {range, <<"key_name_bin">>,
KeyStart, KeyTo}),
...
