It's easy to achieve this in a `single-node` database. But for a `Distributed System`, such as `Milvus`, it's a little difficult; the following problems need to be solved: It's easy to achieve this in a `single-node` database. But for a `Distributed System`, such as `Milvus`, it's a little difficult; the following problems need to be solved:
1. If `u1` and `u2` are on different nodes, and their time clock is not synchronized. To give an extreme example, suppose that the time of `u2` is 24 hours later than `u1`, then all the operations of `u1` can't be seen by `u2` until next day. 1.

To give an extreme example, suppose that the time of `u2` is 24 hours later than `u1`, then all the operations of `u1` can't be seen by `u2` until the next day.
2. Network latency. If `u2` starts the `Search on C0` at `t17`, then how can it be guaranteed that all the `events` before `t17` have been processed? If the events of `delete A1 from C0` has been delayed due to the network latency, then it would lead to incorrect state: `u2` would see both `A1` and `A2` at `t17`. 2. Network latency.
