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?

ACreate and run a Dataflow job that uses JdbcIO to copy data from one Cloud SQL instance to another.

BCreate two Datastream connection profiles, and use them to create a stream from one Cloud SQL instance to another.

CCreate a SQL dump file in Cloud Storage using a temporary instance, and then use that file to import into a new instance.

DCreate 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.

Wait, can you really use a SQL dump for this? Seems risky!

A sounds interesting, but isn't Dataflow overkill for this?

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 think creating a SQL dump file is a common practice we went over, but I’m not clear on how it minimizes performance impact.

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.

Option C looks like the way to go. Using a SQL dump file and then importing it is a straightforward approach that should minimize impact on the running instance.
