Discuss Salesforce Salesforce Certified MuleSoft Developer II (Mule-Dev-301) Exam Topic 2 Question 34

Refer to the exhibit.

A Mute Object Store is configured with an entry TTL of one second and an expiration interval of 30 seconds.

What is the result of the flow if processing between os'store and os:retrieve takes 10 seconds?

AnullPayload

BoriginalPayload

COS:KEY_NOT_FOUND

DtestPayload

Suggested Answer: A

The result of the flow is nullPayload if processing between os:store and os:retrieve takes 10 seconds. This is because the entry TTL of the object store is one second, which means that any stored value expires after one second and is removed from the object store. The expiration interval of 30 seconds only determines how often the object store checks for expired values, but it does not affect the TTL. Therefore, when os:retrieve tries to get the value after 10 seconds, it returns nullPayload because the value has already expired and been removed.

I agree, C makes the most sense here.

Definitely going with C, OS:KEY_NOT_FOUND.

But what if the processing time was shorter? Would it change?

Bo 11 months ago

Wait, how can it expire that fast? Sounds off.

Huey 11 months ago

The entry TTL is 1 second, so it expires quickly.

I practiced a similar question, and I think if the processing takes too long, we might end up with a null payload or something like that.

I’m a bit confused about the expiration interval. Does it mean the object is still available for 30 seconds after being stored?

This kind of question seems familiar; I think if the object expires before retrieval, we might get a key not found error.

I remember that the TTL is really short, just one second, so I'm not sure how that interacts with the 10 seconds processing time.

I'm a bit confused by the different time constraints at play here. I'll need to make sure I fully understand how the Mute Object Store works before I can confidently select the right answer.

Okay, let's think this through. The 30-second expiration interval means the object should still be in the store, but the 1-second TTL means it might have expired by the time it's retrieved. I'll have to weigh the options carefully.

Hmm, the 10-second processing time between os'store and os:retrieve is key here. Given the 1-second TTL, I'm guessing the original payload won't be available by the time it reaches os:retrieve.

This seems like a tricky one. I'll need to carefully consider the time constraints and the Mute Object Store's configuration to determine the outcome.

Kindra 1 year ago

I'm leaning towards originalPayload as the result.

Karl 1 year ago

I believe it will be OS:KEY_NOT_FOUND.

Zack 1 year ago

I think the result will be nullPayload.
