 declaration also includes how the entity's commands are processed, and how events are applied to state. Note that it is 
 impossible to update state from a command handler as it is immutable by design. Updating state only via
 the event handler enables entities to be sourced from their stored events without effects.

 establish a TLS-based connection or even a Unix Domain Socket based connection if desired.
