Google Professional Cloud Database Engineer Exam - Topic 13 Question 27 Discussion

Actual exam question for Google's Professional Cloud Database Engineer exam
Question #: 27
Topic #: 13
[All Professional Cloud Database Engineer Questions]

You are using Compute Engine on Google Cloud and your data center to manage a set of MySQL databases in a hybrid configuration. You need to create replicas to scale reads and to offload part of the management operation. What should you do?

Show Suggested Answer Hide Answer
Suggested Answer: D

PgBouncer maintains a pool for connections for each database and user combination. PgBouncer either creates a new database connection for a client or reuses an existing connection for the same user and database. + PgBouncer is a simple PostgreSQL connection pool that allows for several thousand connections at a time. Using Kubernetes Engine to run a Helm Chart w/ PgBouncer based on the great article from futuretech-industries, we were able to set up an easily deployable system to get the most out of our CloudSQL DBs without breaking the bank. https://medium.com/google-cloud/increasing-cloud-sql-postgresql-max-connections-w-pgbouncer-kubernetes-engine-49b0b2894820#:~:text=That%20is%20where,breaking%20the%20bank.

Using mysqldump and binary logs sounds familiar, but I don't think that's the most efficient way to handle replication in this scenario.

I feel like the Data Migration Service is more for moving data rather than creating replicas, but I could be wrong.

I think using Cloud SQL for MySQL external replica might be the best option since it simplifies management, but I'm not entirely sure.

This seems like a classic cloud migration scenario. I'd start by looking at the Cloud SQL external replica option, as that seems like it would integrate well with the Compute Engine infrastructure we're already using.

I'm a bit confused by the hybrid configuration mentioned in the question. Does that mean we need to consider on-premises servers as well as the cloud? I'll need to make sure I understand the full context before deciding.

Okay, let's think this through step-by-step. We need to scale reads and offload management, so I'm thinking either the Cloud SQL external replica or the Data Migration Service could be good options.

This question kind of reminds me of a similar one about Layer 2 interworking. I feel like nonrouted setups could be an option, but I'm not confident.
