Configurable Channel Duration

[vidalborromeo]

Hi there. I ran into a minor hurdle with this. It would be helpful to be able to configure the channel duration when creating the channel. For example, with the burstiness of my current project, I would be setting the duration to just 30 minutes or less, whereas the default is 2 hours.

For reference, the Channel API has rate-limiting for the number of channel-hours requested per minute...

• Free Tier: 12 hours requested/minute (i.e. max of 6 people open channels within a minute).
• Paid Tier: 180 hours requested/minute (i.e. max of 90 people open channels within a minute).

One possible approach (which is also backwards-compatible) might look like this:

public abstract class ChannelServer extends RemoteServiceServlet implements ChannelService {

    // ADDED THIS
    /**
     * Defaults to 2 hours. Override if needed.
     */
    protected int getChannelDuration() {
        return 2*60;
    }

    protected static void send(String channel, Object o) {
        AutoBean bean = AutoBeanUtils.getAutoBean(o);
        String serialized = AutoBeanCodex.encode(bean).getPayload();

        ChannelServiceFactory.getChannelService().sendMessage(new ChannelMessage(channel, serialized));
    }

    @Override
    public final String join(String channelName) {
        // MODIFIED THIS
        String token = ChannelServiceFactory.getChannelService().createChannel(channelName, getChannelDuration());

        onJoin(token, channelName);
        return token;
    }

    protected abstract void onJoin(String token, String channelName);
}

That's my 2 cents. Cheers :)
