public interface NettyCustomizer
Strategy interface to customize netty Bootstrap and Channel via callback hooks.
Extending the NettyCustomizer API

Contrary to other driver options, the options available in this class should be considered as advanced feature and as such, they should only be modified by expert users. A misconfiguration introduced by the means of this API can have unexpected results and cause the driver to completely fail to connect.
