Another implementation could potentially retrieve or write records to or from a file system.
Any changes made by a writer will not be seen by other users of the database until the changes have been completed (or, in database terms: until the transaction has been committed.) When an MVCC database needs to update a piece of data, it will not overwrite the original data item with new data, but instead creates a newer version of the data item.
To optimize database connectivity, connection pool configurations should be carefully aligned with the database's capacity and the application's specific workload, ensuring efficient connection reuse without overburdening the database server and maintaining a balance between connection availability and resource utilization.
