Distributed Systems  System Design Interview 

Consistency patterns are a set of techniques used to ensure data consistency across distributed systems. They are used to ensure that data is consistent across multiple nodes in a distributed system and that any changes made to the data are propagated to all nodes in the system.

There are several different types of consistency patterns, including:

  1. Eventual Consistency: Eventual consistency is a pattern that ensures that all nodes in the system eventually have the same data, even if it takes some time for the data to propagate.
  2. Strong Consistency: Strong consistency is a pattern that ensures that all nodes in the system have the same data at the same time.
  3. Quorum Consistency: Quorum consistency is a pattern that ensures that a majority of nodes in the system have the same data at the same time.
  4. Read-Your-Writes Consistency: Read-your-writes consistency is a pattern that ensures that any changes made to the data are immediately visible to the node that made the change.
  5. Linearizability: Linearizability is a pattern that ensures that all nodes in the system have the same data in the same order.
