Netty: configure timeout for channel read per channel

I am using Netty framework and implemented client and server. I am making many connections as high as 1000. I want to configure timeout values in multiple places. Some of them i am able to figure out. So, here's the netty behavior of my netty implementation:
1. Many async connections starts from client with the timeout(configured using ChannelOption.CONNECT_TIMEOUT_MILLIS).
2. Those client connections which are able to connect sends HTTP request using channelActive and receives response using channelRead0.

Problem - I want to place timeout value between sending the request and receiving the data for a particular channel.
I read the netty documentation and come up with two solutions:
1. https://netty.io/4.0/api/io/netty/channel/ChannelConfig.html#setConnectTimeoutMillis-int-
2. https://netty.io/4.0/api/io/netty/handler/timeout/ReadTimeoutHandler.html

I am confused which option to choose and which one is better or is there any other option.

You will need to set multiple limits (most likely). As you already found out you may want to set a connect timeout via setConnectTimeoutMillis but also have a ChannelDuplexHandler that will ensure you receive the response to a request in the expected time. You may also want to have a look at IdleStateHandler which will allow to fire events through the ChannelPipeline if the Channel idles for too long.
