# Installing and Configuring the VAST Connector for Dremio

This topic describes how to configure Dremio to work with a VAST Database.

This involves the following:

- installing Dremio
- installing the VAST Dremio connector, which mediates between Dremio and the VAST Database.

## Prerequisites

- Java 11
- Python 3.6
- VAST Database

## Installing Dremio

The VAST Dremio connector can work with either the Dremio Community (open source) version, or the enterprise Commercial version. The commercial version includes add-ons and security features which are not available in the community version.

The instructions below explain how to install the Dremio Community version. See [dremio.com](http://dremio.com ) for details regarding the commercial version.

The connector was tested with Dremio v24.0.0, which can be downloaded from [https://download.dremio.com/community-server/24.3.2-202401241821100032-d2d8a497/](https://download.dremio.com/community-server/24.3.2-202401241821100032-d2d8a497/)

1. Run this command to create a Dremio user

```plaintext
useradd -c "Dremio User" -u 4853 dremio
```
2. Run these commands to install the Dremio community version

```plaintext
dnf install ./dremio-community-24.3.2-202401241821100032_d2d8a497_1.noarch.rpm
systemctl enable dremio
```
3. Run these commands to set up Dremio work directories

```plaintext
mkdir /opt/dremio/log /var/lib/dremio
chown dremio:dremio /opt/dremio/log /var/lib/dremio
```
4. Edit the file /etc/dremio/dremio-env and set the variable `DREMIO_MAX_MEMORY_SIZE_MB `to limit memory usage by Dremio. In this example, the limit is 200GB.

```plaintext
DREMIO_MAX_MEMORY_SIZE_MB=200000
```
5. Run this command

```plaintext
systemctl start dremio
```

## Downloading and Installing the VAST Connector

Download the latest Dremio Connector for VAST Database from here: [https://github.com/vast-data/vast-dremio-connector/releases](https://github.com/vast-data/vast-dremio-connector/releases). The connector is a jar file.

Copy the Dremio Connector jar file to `${DREMIO_HOME}/jars`.

## Configuring the Connector

After downloading the VAST Dremio Connector, follow these steps to configure a Data Source on Dremio with the connector.

1. Navigate to the Dremio UI (typically at http:/dremio_coordinator_host:9047), and then to Data Sets.
2. Click Add Source to add a Data Source.
3. In the Add Data Source dialog enter these details

  - **Name** - the name of the data source (any text)
  - **Endpoint**: An IP address in the VIP Pool on the VAST Cluster
  - **Region**: vast
  - **Access Key**: The Access Key for the service accessing VAST
  - **Secret Key**: the Secret key for the service accessing VAST
4. It is recommended, but optional, to add these advanced settings:

  - **Additional Endpoints**: A list of IPs from the VAST VIP Pool on the Cluster. Additional endpoints improves performance.
  - **Max Number of Splits**: typically the number of CPU threads available for each worker; recommended value 32
  - **Max Number of Subsplits**: 4
5. Click Save.

## Using the Dremio and the VAST Dremio Connector to Access a VAST Database

1. Run Dremio from your browser.
2. Select the VAST Data Source. This will show a list of Databases on the VAST Cluster.
3. Select a database.
4. Create and run queries from the query bar. See [https://docs.dremio.com](https://docs.dremio.com ) for more details for using Dremio.
