*Root and child contexts*

Before reading further, please understand that –

 - Spring can have multiple contexts at a time. One of them will be root context, and all other contexts will be child contexts.
 - All child contexts can access the beans defined in root context; but opposite is not true. Root context cannot access child contexts beans.

The CAP theorem states that when a total partition (a network failure, for
example) or a temporary partition (the latency between data replication after a write
request, a full GC in the JVM, etc) happens in a distributed system, it has to choose
between consistency or availability. If the distributed system picks consistency over
availability, it will be unavailable until the partition is fixed. On the other hand, if it
picks availability over consistency, it will return a response for a request but this
may not contain the most up to date data.
