# Select API Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

Traditional retrieval of objects is always as whole entities, i.e GetObject for a 5 GiB object, will always return 5 GiB of data. S3 Select API allows us to retrieve a subset of data by using simple SQL expressions. By using Select API to retrieve only the data needed by the application, drastic performance improvements can be achieved.

# CI Pipeline Configuration

## Open & import the project

In your IDEA, `File` - `Open`, select `.teamcity/pom.xml`, `import as project`, and you'll have a Maven project.

## Project structure

Mostly a standard Maven project structure. The entry point `settings.kts` defines the TeamCity project.

There are 3 subprojects in the TeamCity project hierarchy: `Check` for Gradle builds, `Promotion` for releasing Gradle versions, `Util` for miscellaneous utilities.

    select("tr.severity-$severity").map { tr ->
        tr.select("td")[1]
            .select("span")
            .text()
            .substringBefore(" If you did this intentionally")
    }

    select("tr.severity-$severity").map { tr ->
        val entry = tr.select("td")[1]

by a different role than the prod version.

The intended users of this repo are users running Istio in production who want to select, tune
and understand each binary that gets deployed, and select which combination to use.

Note: each component can be installed in parallel with an existing Istio 1.0 or 1.1 installation in

* "Add configuration...".
* Select "Python"
* Run the debugger with the option "`Python: Current File (Integrated Terminal)`".

It will then start the server with your **FastAPI** code, stop at your breakpoints, etc.

Here's how it might look:

If you use Pycharm, you can:

* Open the "Run" menu.
* Select the option "Debug...".

the go_ios_$GOARCH_exec wrapper is found. For example, to run the archive/tar tests:

	export PATH=$GOROOT/bin:$PATH
	GOOS=ios GOARCH=amd64 CGO_ENABLED=1 go test archive/tar

The go_ios_exec wrapper uses GOARCH to select the emulator (amd64) or the device (arm64).
However, further setup is required to run tests or programs directly on a device.

First make sure you have a valid developer certificate and have setup your device properly
