Instructor: The optimize ribbon in Power BI Desktop

is set up to help report authors and developers

more effectively build and create reports.

Now, it's important to note

that while the features included in this ribbon

can be useful for all reports,

they may be specifically useful

for reports built using direct query data sources.

So, if you think back to that lecture

in the power query section

where we talked about the different types

of connections and storage modes,

well, here's an area where understanding the pros and cons

that we outlined in that lecture

of the different storage modes

really come into play.

Now, the main reason why direct query reports

will find these features particularly useful

is because reports built with direct query connections

send all of those queries back to the data source

every time something changes.

So, using these features, like pausing queries,

are helpful because it allows you

to make a bunch of changes to a report

and not send the query back to the data source

after each change or update is made to the report.

Our next option here, optimization presets.

These contain a few different

predefined optimization presets

that can be applied

based on your data connection and storage method.

So, we'll dig into these options in a bit more detail later.

But again, these presets

are geared towards direct query connections.

Next up, we've got performance analyzer,

which is a fantastic tool

that can be used regardless

of the connection method or type.

Now the performance analyzer,

it basically records all of the interactions

and query load times within your report,

and then it displays them for you in meaningful categories.

Now, if you're using a visual

that is built from a direct query source,

the performance analyzer

will actually include a specific row

just for that direct query data source.

If not, it's still a great tool

to help report authors understand their report performance

and also identify areas that may need to be optimized.

And then, last but not least here,

there's an apply all slicers option

which allows report authors

to either apply or clear all slicers on our page.

Now, this optimization tool is most useful

when your report contains multiple slicers.

All right, so I just wanna mention one more thing

before we move on.

The optimization tab,

it's currently a preview feature, right?

So it actually needs to be enabled

from the preview features menu.

Keep in mind that it'll likely change or evolve

before it becomes generally available.

So, the goal of the next few lectures

isn't to provide a comprehensive guide,

but it's really just to get you acquainted

with the features that are available

and how they can be used

to optimize your Power BI report development.
