All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler

public class P2PFileTransferClientHandler
extends io.netty.channel.SimpleChannelInboundHandler<io.netty.handler.codec.http.HttpObject>

The client-side Netty handler to process responses for P2P file transfer. It's not shareable among multiple requests since it maintains the states for a single partition. It's important to note that this handler is operated in a single thread, and it processes file transfers sequentially.
