defmodule MyApp.RepoConnectionReaper do
  @moduledoc """
  Disconnect all connections after a X minutes to reset cache build-up and leaky memory on long-lived connections
  Especially useful for dynamic queries which contribute to this build-up.
  
  Alternatively, use this Repo option e.g. `Repo.all(query, prepare: :unnamed)` to avoid using named prepared statements
  on queries that are dynamic enough to not cache the prepared statement on the connection.
