Avoiding Duplicate Invoice Numbers Due to Sync Timing Issues

Concurrent requests may assign the same invoice number when the new value is fetched before the previous order is stored.

public void ProcessOrder(object orderInfo) {
    lock(lockObj) {
        int uniqueId = GetUniqueId();
        orderInfo.Id = uniqueId;
        CommitOrder(orderInfo);
    }
}

i think addin a distrubuted sequence gen or use a db sequence can help. lock alone may not be enuf in real distributed enviroments. might also be worth checkin on race condtions with network lag

In practice, the approach of using a simple local lock may work for small-scale systems, but as the system scales to multiple nodes, this technique often becomes a bottleneck. Experience has shown that integrating a centralized service, such as a database sequence or a dedicated ID generation service, provides a more robust solution. This not only mitigates race conditions across distributed environments but also simplifies consistency checks when the system experiences heavy concurrent load. It is advisable to evaluate the performance characteristics of your solution as you scale to ensure ongoing reliability.

hey, i think the lock helps, but im wonderin if its enuf for distributed systems. have u looked into sequence services to handle unique ids across nodes? any experince with that idea?
