Variables

ConsistencyLevel.Strong

str

Strong Consistency guarantees that read operations always return the value that was last written.

ConsistencyLevel.BoundedStaleness

str

Bounded Staleness guarantees that reads are not too out-of-date. This can be configured based on number of operations (MaxStalenessPrefix) or time (MaxStalenessIntervalInSeconds).

ConsistencyLevel.Session

str

Session Consistency guarantees monotonic reads (you never read old data, then new, then old again), monotonic writes (writes are ordered) and read your writes (your writes are immediately visible to your reads) within any single session.

ConsistencyLevel.Eventual

str

Eventual Consistency guarantees that reads will return a subset of writes. All writes will be eventually be available for reads.

ConsistencyLevel.ConsistentPrefix

str

ConsistentPrefix Consistency guarantees that reads will return some prefix of all writes with no gaps. All writes will be eventually be available for reads.
