BASE.
also: BASE propertiesBasically available, soft state, eventually consistent: the availability-first alternative to ACID used by many distributed stores.
the two-minute refresher
- Basically available: the system always answers, maybe with stale data.
- Soft state: data can change without new input as replicas converge.
- Eventually consistent: with no new writes, all replicas end up the same.
- Trade-off: high availability and scale in exchange for weaker guarantees.
