What happens to new requests while the current transaction is being processed?

When a system is processing a current transaction, new requests are queued. This means that any additional requests that are made while the current transaction is still being handled will not be processed immediately. Instead, they will wait in a queue until the system is ready to process them.

Queuing is a common practice in transaction processing systems to ensure that transactions are handled in a reasonable order and that system performance remains stable. It prevents conflicts and errors that could arise from multiple transactions being processed simultaneously. This orderly management allows for efficient handling of requests without overwhelming the system, ensuring that each request is eventually addressed after the current transaction has been fully processed.

In contrast, automatic approval of transactions, open submissions during processing, or discarding new requests would not support systematic transaction management or integrity, which is why these alternatives are not the correct approach in this context.
