Sample Question:
Your company plans to relocate an essential MySQL database from an on-site server to Cloud SQL for MySQL. The on-premises database utilizes a MySQL version compatible with Cloud SQL and leverages the InnoDB storage engine. Your task is to ensure a migration process that maintains transaction integrity with minimal downtime. How should you proceed?
Answer Options:
A. Utilize Database Migration Service to establish connectivity with the on-premises database, opting for continuous replication. Once the migration is done, promote the Cloud SQL for MySQL instance and redirect your applications to this instance.
B. Create a distinct Cloud Data Fusion pipeline for each table to transition data from the on-premises MySQL database to Cloud SQL for MySQL. Arrange a downtime period to execute each Cloud Data Fusion pipeline. Confirm the success of the migration. Relink the applications to the Cloud SQL for MySQL instance.
C. Halt the on-premises applications. Apply the mysqldump tool to back up the database content in a compressed format. Employ gsutil –m to transfer the dump file to Cloud Storage. Utilize Cloud SQL for MySQL's import feature. Upon completion of the import, redirect the applications to the Cloud SQL for MySQL instance.
D. Halt the on-premises applications. Apply the mysqldump tool to back up the database content in CSV format. Employ gsutil –m to transfer the dump file to Cloud Storage. Utilize Cloud SQL for MySQL's import feature. Upon completion of the import, redirect the applications to the Cloud SQL for MySQL instance.
Correct answer below
Correct Answer: A
Explanation: Database Migration Service supports continuous replication, ensuring transaction integrity and minimizing downtime during migration. Other options increase downtime or complexity, making them less ideal.
Why Other Options Are Incorrect:
Option B:
This approach uses Cloud Data Fusion pipelines, which adds unnecessary complexity. Creating individual pipelines for each table can lead to increased operational overhead and potential risks of data consistency issues. Additionally, this method involves scheduling a downtime period, which fails to meet the "minimal downtime" requirement.
Option C:
Using mysqldump with compressed backups, followed by transferring the dump file to Cloud Storage and importing it into Cloud SQL, requires halting the applications during the process. This approach introduces significant downtime. Furthermore, mysqldump doesn’t inherently preserve ongoing transactions, making it less suitable for scenarios where transaction integrity is critical.
Option D:
Similar to Option C, this option relies on mysqldump, but in CSV format. While the method aligns with traditional migration techniques, it involves stopping the applications, leading to extended downtime. CSV files can also cause formatting issues or loss of database constraints, further complicating the migration and potentially compromising data integrity.
