preconnect()

public

Preconnect all connections in the pool. This saves pool users from having to wait for a connection to be established when first using it after checkout.

      def preconnect
        sequential_maintenance -> c { (!c.connected? || !c.verified?) && c.allow_preconnect } do |conn|
          conn.connect!
        rescue
          # Wholesale rescue: there's nothing we can do but move on. The
          # connection will go back to the pool, and the next consumer will
          # presumably try to connect again -- which will either work, or
          # fail and they'll be able to report the exception.
