问题
I'd like to compile a reasonably complete list of distributed process registry libraries for Erlang.
Such libraries need to support basic operations like register_name(Pid, Name) and whereis_name(Name) (and ideally registered_names/0). Names shouldn't be restricted to atoms only, and these registration/lookup operations need to work reasonably reliably with multiple nodes participating in the registry (ignoring partitions for now).
So far I've come up with global, gproc and nprocreg. What others are available?
回答1:
I would argue that riak_core is such. I use its partition ring + consistent hashing to find the node, together with a local gproc instance to find the exact process. Thus I get very fine balance between fault tolerance, availability and speed.
回答2:
Locker is used in several projects at wooga for registering processes.
Riak PG is a "work in progress" alternative to pg2. The source code also serves as a nice example of how to use riak_core.

Regarding Riak PG:
It's mainly considered a "work in progress," because it was the result of some research that wasn't tested in production. Here's a link to the Erlang Workshop 13 paper.
If anyone has any questions regarding Core, or using PG in particular, I'd be happy to help out any way that I can.
