# Installing Bulk Data Import

You can import data using Treasure Data’s open-source bulk data loader Embulk. Embulk helps transfer data between various databases, storage locations, file formats, and cloud services. For more information, see the [Embulk documentation](http://www.embulk.org/docs/).

## Prerequisites

* Basic knowledge of Treasure Data
* Basic knowledge of [Embulk](http://www.embulk.org/docs/)
* Java installed (Embulk is a Java application)
* [JRuby](https://www.jruby.org/download) installed and configured (Embulk v0.10.50 and v0.11.0 do not include JRuby; see the "JRuby" section of [Embulk v0.11 is coming soon](https://www.embulk.org/articles/2023/04/13/embulk-v0.11-is-coming-soon.md))


## Installing Embulk from the Command Line

| Platform | Steps |
|  --- | --- |
| Linux / macOS / BSD (UNIX) | Run: |



```bash
curl --create-dirs -o ~/.embulk/bin/embulk -L "http://dl.embulk.org/embulk-latest.jar"
chmod +x ~/.embulk/bin/embulk
echo 'export PATH="$HOME/.embulk/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc
```

Windows (PowerShell)|Run:


```powershell
Invoke-WebRequest http://dl.embulk.org/embulk-latest.jar -OutFile embulk.bat
```

## Installing the Embulk Treasure Data Plugin

Embulk plugins load data to or from various systems and file formats. See the [list of Embulk plugins](https://plugins.embulk.org/).

Install the `embulk-output-td` plugin (imports records to Treasure Data):


```bash
embulk gem install embulk-output-td
```

## Using a Proxy Server

If you cannot upload, verify whether your network uses a proxy. Set the proxy with command-line options:

Linux:


```bash
embulk -J-Dhttp.proxyHost=HOST -J-Dhttp.proxyPort=PORT -J-Dhttp.proxyUser=USER -J-Dhttp.proxyPassword=PASS run config.yml
```

Windows:


```powershell
embulk.bat "-J-Dhttps.proxyHost=HOST" "-J-Dhttps.proxyPort=PORT" "-J-Dhttp.proxyUser=USER" "-J-Dhttp.proxyPassword=PASS" run config.yml
```

Or run via Java directly:


```bash
java -Dhttps.proxyHost=HOST -Dhttps.proxyPort=PORT -jar embulk.bat run config.yml
```
