BASE josedacruz, September 11, 2023 BASE Transactions is a transaction model often used on databases that rely heavily on horizontal scaling and performance. BA: Basic Availability: The database looks like it is always available. S: Soft-state: The database doesn’t enforce consistency. Developers should have this responsibility. E: Eventual consistency: The consistency can be delayed. Some “reads” can still use “old” values. NoSQL databases tend to use this kind of transaction model. It is commonly used in large-scale, performant systems using sharding and horizontal scale-out. Don’t require locking or rollback actions. Eventual synchronization and reconciliation of nodes should be enough. Data replication can use a Master-Slave, Master-Master, Multi-Master, and Peer-to-Peer configuration. Products: Cassandra, Hadoop, DynamoDB, BigTable, MongoDB, Redis. ACID: Provides a consistent system. BASE: Provided high availability.
