Discuss a scenario where data consistency is crucial and how you would ensure it while using a NoSQL database in Go.

In a scenario like implementing a real-time stock trading platform, data consistency is critical. Any inconsistency or delay in updating stock prices could lead to financial losses. To ensure data consistency while using a NoSQL database in Go, you would employ techniques like using a distributed database with strong consistency guarantees, implementing idempotent operations, and handling transactions carefully. Additionally, you could utilize Go's concurrency mechanisms to ensure that updates and reads are synchronized appropriately to maintain data integrity. For less critical applications, eventual consistency might be acceptable, but for financial systems like stock trading, strong consistency is a must.
