What it shows

  • Network Partitions are inevitable physical realities across distributed nodes.
  • CP systems reject requests to prevent serving stale or conflicting writes.
  • AP systems accept writes and reads, trading off immediate global consistency.

The takeaway

In a network partition, you must choose between stale data or system errors.
