All right, you have made it to section 10.
This is the last real section before the wrap-up.
In this section, we're going to talk about "Optimizing
"and Troubleshooting Data Storage and Processing."
So just for reference, you are right here.
Yeah, that's right.
You're at the very end.
So make sure that you keep focused, and let's jump through
and finish out this section.
So in this section, we're going to talk about handling.
So how do we handle data skew?
How do we handle data spill?
We're going to talk about tuning.
So how do we shuffle partitions?
And how do we do queries using indexers?
And queries using cache?
And then we'll talk about optimizing.
So resource management, pipelines, and I'll tell you,
this is a pretty big section.
So there's actually quite a bit more
in little, small topics that we'll mix
into these 3 main points for optimization.
Some key points to remember as you jump into this section.
1: Focus, this is the last section before the end.
Don't get distracted. Push through and finish strong.
Don't forget about the big picture.
So when we talk about all these little individual topics,
make sure that you're keeping the service in mind,
and make sure that you're keeping the big picture.
And that ties into: don't forget scenarios and labs.
Right? So as we think about the big picture of how all
of this optimization and security plays in together,
you want to think about that in terms of scenarios as well.
So how could you use that in your work?
Or how could you use that if you were standing up
a big data environment, right?
And don't forget about labs.
Labs help you on the exam. Make sure
that you're doing the labs.
And make sure that you're not just doing the labs once,
but you're doing the labs enough
that you can do those on your own.
With that, hey, let's jump in to section 10.
See you there.
