@Randgalt do you think this new feature would be useful for Curator and for
local testing of apps which use ZooKeeper ?
> Allow to subclass ClientCnxnSocketNetty and NettyServerCnxn in order to use
> Netty Local transport
> -------------------------------------------------------------------------------------------------
>
> Key: ZOOKEEPER-2755
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2755
> Project: ZooKeeper
> Issue Type: New Feature
> Components: java client, server
> Affects Versions: 3.5.2
> Reporter: Enrico Olivelli
>
> ClientCnxnSocketNetty and NettyServerCnxn use explicitly InetSocketAddress
> class to work with network addresses.
> We can do a little refactoring to use only SocketAddress and make it possible
> to create subclasses of ClientCnxnSocketNetty and NettyServerCnxn which
> leverage built-in Netty 'local' channels.
> Such Netty local channels do not create real sockets and so allow a simple
> ZooKeeper server + ZooKeeper client to be run on the same JVM without binding
> to real TCP endpoints.
> Usecases:
> Ability to run concurrently on the same machine tests of projects which use
> ZooKeeper (usually in unit tests the server and the client run inside the
> same JVM) without dealing with random ports and in general using less network
> resources
> Run simplified (standalone, all processes in the same JVM) versions of
> applications which need a working ZooKeeper ensemble to run.
> Note:
> Embedding ZooKeeper server + client on the same JVM has many risks and in
> general I think we should encourage users to do so, so I in this patch I will
> not provide official implementations of ClientCnxnSocketNetty and
> NettyServerCnxn. There will be implementations only inside the test packages,
> in order to test that most of the features are working with custom socket
> factories and in particular with the 'LocalAddress' specific subclass of
> SocketAddress.
> Note:
> the 'Local' sockets feature will be available on Netty 4 too
