Phoenix PubSub adapter based on PG2. To use it as your PubSub adapter, simply add it to your Endpoint's config file (see e.g.: test/test.config):

   [
    {ebus,
     [
      {pubsub,
       [
        {adapter, ebus_ps_pg2},
        {pool_size, 5},
        {name, ebus_ps_test}
       ]
      }
     ]
    }
   ].

• name: The name to register the PubSub processes, ie: ebus_ps.
• pool_size: Both the size of the local pubsub server pool and subscriber shard size. Defaults 1. A single pool is often enough for most use cases, but for high subscriber counts on a single topic or greater than 1M clients, a pool size equal to the number of schedulers (cores) is a well rounded size.
