Data System Architecture


NewSQL are distributed database that prioritize consistency over availability - See Distributed Database - CAP Theorem (Consistency, Availability, Partition Tolerance)


Network failure

In the event of a network partition, A CP system:

  • will return an error or a time-out due because the information cannot be guarantee to be up to date
  • and therefore experience a reduction in availability.
