Gproc is an extended process registry and dictionary for Erlang/OTP, supporting arbitrary-term aliases, multiple registrations, counters, and a global (multi-node) registry. It also enables pub/sub messaging and QLC/match-spec based queries over registered process metadata.

Use cases

• register erlang processes under custom aliases
• build publish-subscribe messaging in erlang
• find processes by metadata in a running system
• wait for a process to register itself
• maintain aggregated counters across processes
• share a registry across a cluster of erlang nodes
• give away a registered name to another process atomically

When to choose

• you need richer process naming than Erlang's built-in `whereis/1` allows
• you want pub/sub or process discovery patterns in an Erlang/Elixir app
• you need a global registry spanning multiple nodes

When to avoid

• you only need simple single-name registration, which the built-in Erlang registry handles
• your system cannot tolerate the overhead of a central registry process
