Google Professional Data Engineer Exam - Topic 6 Question 21 Discussion

You are running a pipeline in Cloud Dataflow that receives messages from a Cloud Pub/Sub topic and writes the results to a BigQuery dataset in the EU. Currently, your pipeline is located in europe-west4 and has a maximum of 3 workers, instance type n1-standard-1. You notice that during peak periods, your pipeline is struggling to process records in a timely fashion, when all 3 workers are at maximum CPU utilization. Which two actions can you take to increase performance of your pipeline? (Choose two.)
B) Use a larger instance type for your Cloud Dataflow workers and E) Create a temporary table in Cloud Spanner that will act as a buffer for new data. Create a new step in your pipeline to write to this table first, and then create a new pipeline to write from Cloud Spanner to BigQuery
A) Increase the number of max workers
C) Change the zone of your Cloud Dataflow pipeline to run in us-central1
D) Create a temporary table in Cloud Bigtable that will act as a buffer for new data. Create a new step in your pipeline to write to this table first, and then create a new pipeline to write from Cloud Bigtable to BigQuery

More workers and bigger instances should do the trick!

I think creating a buffer in Bigtable is overkill for this situation.

Wait, changing the zone to us-central1? Isn't that slower for EU data?

Increasing the number of max workers is a solid move!

Changing the zone to us-central1 doesn't seem right since we're already in europe-west4. I don't think that would help with performance.

I think we practiced a similar question where increasing workers helped. I feel like option A and B could work well together.

I'm a bit unsure about the instance types. Would switching to a larger instance type really make a significant difference?

I remember we discussed increasing the number of max workers to handle more load during peak times. That seems like a solid option.

Okay, let me break this down. The key here is that we need to give the User on the Reviewer_c record read-only access to the Defect_c record. I think Apex managed sharing or criteria-based sharing might be the way to go.

Hmm, I'm not too familiar with the Cisco Unity Connection restriction table. I'll need to think this through carefully.

Okay, I've got an idea. If we use Proof instead of [PREVIEW], that should prevent the prefix from deploying in the live sends. I'm feeling confident about that.

This looks like a pretty straightforward question about HTML5 audio support. I think I can handle this one.

Okay, let's see. I think the key here is whether the new requirements are immediately enforced on existing passwords or not. I'll have to weigh the options carefully.
