Project Modules

There are no modules declared in this project.

An implementation of natural batching for netty channels to gather writes into fewer syscalls.

Usage

Replace calls to Channel.flush() and ChannelHandlerContext.flush() with calls to BatchFlusher.flush(). BatchFlusher will then gather multiple flushes into fewer calls to Channel.flush().

At that point the actual gathering write can be left to Netty to perform using the underlying GatheringByteChannel. Alternatively the write() and flush() methods of ChannelOutboundHandler can be implemented to perform custom e.g. ByteBuf consolidation.
