WebMar 5, 2024 · CAP theorem states that a distributed data store can only have 2 of 3 properties. The properties are consistency, availability, and partition tolerance (network failure). As a result, designers were forced to pick a combinations of CA, CP, and AP. Another important feature of the SQL database is ACID compliance. WebJan 15, 2016 · Paxos and Raft are algorithms for doing this. In these systems, a write is considered to be committed if a majority of the nodes in the network accept it. ...

This was mostly during raft failovers or instability; because Consul uses a strongly-consistent store its availability will always be weaker ... WebThe CAP theorem states that it is impossible for a distributed database to provide consistency, availability, and partition tolerance simulataneously -- that, in the face of a network partition, the database can be available or consistent, but not both. Raft is a Consistency-Partition (CP) protocol.

WebIt does so by combining the Raft consensus algorithm for writes and a custom time-based synchronization algorithms for reads. ... In the CAP theorem, availability is a binary property, but for High Availability, we talk about availability as a spectrum (using terms like "five nines" for a system that is available 99.999% of the time).
