A customer has launched a data analytics initiative and has been transferring old data into the new data lake. The customer has discovered some data read errors during the transfer process.
In this scenario, how should the customer have avoided these data integrity issues?
Data integrity issues can often be prevented by ensuring that mechanisms for data assurance and media scanning are activated.
Data Assurance (DA) is a feature that verifies the integrity of the data as it is read from or written to the storage system, detecting and correcting errors.
Media scan is a background process that checks the entire disk surface for errors and corrects any found before they cause data integrity issues.
Together, these features ensure ongoing data integrity by preemptively identifying and fixing potential issues.
