I&#x27;d like to know more about:<p>* clustering - what kinds of clusters are supported? How do they scale? Do they favor availability or consistency?<p>* security - is there any authentication? authorization for certain resources? TLS?<p>* guarantuees for delivery? Transactional modes?<p>* what does the wire protocol look like? Support for meta data?<p>I clicked around the website and documentation a bit, and didn&#x27;t find any answers.
