Consistency patterns

• Eventual consistency: Eventually, all reads will return the last updated value
• Monotonic reads: A read will always return the same value or a more recent value than the previous read
• Monotonic writes: For a given process, any write is completed before any successive write operation
• Read-your-writes: Any write by a given process will be available to that same process for read operations
• Sequential consistency: Writes aren't necessarily seen instantaneously, but ordering of writes appears consistent across all processes
• Strict consistency: Every parallel process observes the same consistent state
