Conditional Update. What if D is a third-party key-value storage that does not support Conditional Update? At this time, we can add a P between L and D as the proxy. All CRUD operations must pass through P, so that P can perform condition checks, while the actual data operations are placed in D. This method achieves the separation of condition checks and data operations, but also reduces the performance. You need to add cache in P to improve the performance. Because P is the only client of D, t

is that the above approach assumes that D is capable of supporting conditional update. So. What if D is a third-party Key-value store that does not support conditional update? At this point, we can add a p as a proxy between L and D, and all crud operations must go through p. Let p do the condition check. and the actual data operations are placed in D. This approach enables the separation of condition checking and data manipulation. But at the same time reducing performance, you need to add the
