We now connect asynchronously to expose non-blocking connection behavior for reactive API usage. We also use a non-blocking, asynchronous pool implementation for connections that are used through a reactive API. Shared connection usage, which is blocking on the very first access can be pre-initialized during connection factory initialization instead of initialization on first access:
LettuceConnectionFactory connectionFactory = new LettuceConnectionFactory();
connectionFactory.setEagerInitialization(true);
connectionFactory.afterPropertiesSet();
We no longer require offloading of blocking connects to a dedicated scheduler which makes reactive API usage fully non-blocking.
