[erlang-questions] API design and pgapp
Tue Sep 5 18:21:37 CEST 2017
I'm jumping back into the world of Erlang, and among other things,
work on pgapp, a higher level interface for Postgres.
This came up, lately: https://github.com/epgsql/pgapp/issues/22
Which seems to pit two things against one another:
* On one hand, using the process registry to keep track of the Conn
(connection) is not very Erlang-y and might introduce errors.
* That said, it's also nice for things to be composable in the sense
that you can write, say, update_stats() either within the transaction
or outside and have it 'just work' without having to provide both an
update_stats() and update_stats(Conn).
