Which of the following is NOT one of the three main types of triggers that Dataflow supports?

Show Suggested Answer Hide Answer
Suggested Answer: A

There are three major kinds of triggers that Dataflow supports: 1. Time-based triggers 2. Data-driven triggers. You can set a trigger to emit results from a window when that window has received a certain number of data elements. 3. Composite triggers. These triggers combine multiple time-based or data-driven triggers in some logical way

I thought size was a factor too, but I guess not!

Wait, is there really no size-based trigger?

B is actually a valid type, so A must be the answer.

I remember studying the three main types, but I can't shake the feeling that element size might actually be one of them.

I’m pretty sure that triggers based on time and count are correct, but I’m unsure about the combination one.

I vaguely recall a practice question about triggers, and I don't think element size was mentioned as a main type.

I think the triggers are based on time, count, and something else, but I can't remember if size is one of them.

I'm pretty confident the answer is A. Dataflow's main trigger types are time-based, element count-based, and composite triggers that combine other triggers. Element size in bytes doesn't sound like one of the core trigger options.

Okay, let me see. I know Dataflow has triggers based on time, element count, and a combination of other triggers. I don't think element size in bytes is one of the main trigger types, so I'll go with A.

Hmm, I'm a bit unsure about this one. I know Dataflow has different types of triggers, but I can't remember the exact three main ones off the top of my head. I'll have to think this through carefully.

I'm pretty sure the answer is A. Dataflow supports triggers based on element count, time, and a combination of other triggers, but I don't think it supports triggers based on element size in bytes.

Time-based triggers? How about a trigger that only fires when the moon is full and the stars align? Just keeping it realistic, you know.

Hmm, I'd say the answer is B. A combination of other triggers sounds like a fun way to complicate things.

A trigger based on element size in bytes? What kind of sorcery is this? Surely that's not a real option.
