pub enum StreamConsistencyLevel {

}Expand description
Consistency semantics for stream read and write operations.
These map to well-known distributed-systems consistency models.
Variants§
Eventual
Replicas converge eventually; no ordering guarantees.
ReadYourWrites
A client always reads values it previously wrote.
MonotonicRead
Read responses are non-decreasing in version for a session.
MonotonicWrite
Write responses are non-decreasing in version for a session.
Strong
All reads reflect all preceding writes globally.
Linearizable
Operations appear instantaneous and globally ordered.
