What happens when multiple transactions occur in a short time?

When multiple transactions occur in a short time, it is important to understand the system's capacity to handle these transactions. The scenario where transactions may be rejected is plausible when a system's processing capability is overwhelmed. This can happen due to factors like system overload, insufficient resources, or predetermined limits on transaction volume. When too many transactions are submitted simultaneously, the system might not be able to validate or process them all. As a result, it may reject some transactions to maintain overall system performance or integrity.

Other potential outcomes, such as prioritizing transactions or saving them for later processing, may occur in well-structured systems with robust handling capabilities. However, a system under pressure can default to rejecting some transactions to prevent failures or errors, emphasizing the importance of capacity and transaction management in real-time systems.
