Ah, if EventBridge was there from the day one, it makes more sense.

Nonetheless, we now have two services where I can send my customers events, with similar features.

Would it be safe to say that SQS is better for my app events, while EventBridge is more for AWS events?

But, when EventBridge was introduced in 2019, every service had to be modified to write events to it. Surely it would be possible to add SQS target instead?

Thanks. It seems Gemini API does have context caching, so I might give it a try.
