Google Professional Cloud Database Engineer Exam - Topic 10 Question 14 Discussion

You are choosing a database backend for a new application. The application will ingest data points from IoT sensors. You need to ensure that the application can scale up to millions of requests per second with sub-10ms latency and store up to 100 TB of history. What should you do?
C) Use Memorystore for Memcached, and add nodes as necessary to achieve the required throughput.
A) Use Cloud SQL with read replicas for throughput.
B) Use Firestore, and rely on automatic serverless scaling.
D) Use Bigtable, and add nodes as necessary to achieve the required throughput.

Wait, can Memorystore even manage that kind of load?

D sounds solid, but can it really handle 100 TB?

Bigtable sounds like a good fit since it’s designed for high throughput and can scale easily, so I’m leaning towards option D.

I feel like Memorystore is more for caching rather than long-term storage, so option C seems off to me.

I think Firestore could work for automatic scaling, but I’m not confident it can handle the latency requirements.

I'm a bit confused by the wording of these options. I'll need to re-read them a few times to make sure I understand the differences.

I think the best option is definitely A, since we want to follow the requirements clearly for naming in the SOAP message.

Hmm, I'm a bit confused on this one. I thought there was a way to prevent the contract address from changing, but I can't remember the details. I'll have to think this through carefully.

B seems right - there's no guaranteed order of execution, so I'll need to design my code to handle that scenario.

Cloud SQL with read replicas? Really? That's like trying to use a bicycle to haul a freight train. This application needs serious big-data firepower, not your grandpa's SQL database.

Ooh, Memorystore for Memcached? That's an interesting idea! But I'm not sure if it can keep up with the insane throughput and data volume this application needs. Definitely not a good fit in my opinion.

I'm not so sure about Bigtable. What about Firestore? It's serverless, so you don't have to worry about scaling it up yourself. And it can probably handle the data volume and throughput requirements.

Hmm, I think option D is the way to go. Bigtable can handle massive amounts of data and scale up to millions of requests per second. Plus, it's designed for time-series data like IoT sensor data.
