- bounded staleness
- consistent prefix
Strong - This consistency level offers serving requests concurrently and the reads are guaranteed to return the most recent (last committed) version of the item.
Bounded Staleness - This consistency level offers consistent prefix guarantee where by reads might lag behind writes by at most "K" versions (i.e., "updates") of an item or by "T" time interval.
Session - This consistency level offers consistent prefix monotonic reads, monotonic writes, read-your-writes, and write-follows-reads guarantees. Clients outside of the session performing writes will see eventual consistency.
Consistent Prefix - This consistency level offers guarantee that reads never see out-of-order writes.
Eventual - There's no ordering guarantee for reads. In the absence of any further writes, the replicas eventually converge.
