Google Professional Cloud Database Engineer Exam - Topic 8 Question 13 Discussion

You need to perform a one-time migration of data from a running Cloud SQL for MySQL instance in the us-central1 region to a new Cloud SQL for MySQL instance in the us-east1 region. You want to follow Google-recommended practices to minimize performance impact on the currently running instance. What should you do?
A) Create and run a Dataflow job that uses JdbcIO to copy data from one Cloud SQL instance to another.
B) Create two Datastream connection profiles, and use them to create a stream from one Cloud SQL instance to another.
C) Create a SQL dump file in Cloud Storage using a temporary instance, and then use that file to import into a new instance.
D) Create a CSV file by running the SQL statement SELECT...INTO OUTFILE, copy the file to a Cloud Storage bucket, and import it into a new instance.

I vaguely remember something about using CSV files for data export, but I’m not confident it’s the right approach for migrating between regions.

I feel like the Dataflow job option could be efficient, but I can't recall if it’s recommended for this specific scenario.

I remember we discussed using Datastream for real-time data migration in class, but I'm not sure if it's the best option for a one-time migration.

Wait, is the exponent supposed to be applied to the whole expression or just the 3? I'm a little confused on how to approach this.

Option C is the way to go, but I gotta say, Option D with the CSV file is like trying to use a sledgehammer to crack a walnut. Sometimes, the simplest solutions are the best.
