PACELC extension

What does PACELC add to CAP?
Options
  1. 1It replaces the consistency axis of CAP with durability, arguing writes must survive a majority node failure
  2. 2It applies only to single-node databases, adding a latency-versus-consistency choice when replication is absent
  3. 3It proves partition tolerance is fundamentally impossible, so every distributed system must sacrifice it in practice
  4. 4It states that even without partitions (else), a system must trade off latency versus consistency
