# Upload a Parquet file

> Upload a Parquet file into NexusOne.

This tutorial walks you through how you can upload a Parquet file into the NexusOne platform.

## Prerequisite

Appropriate permission: `nx1_ingest`, `nx1_monitor`, `nx1_s3_admin`, `airflow_user`, `superset_user`,
`spark_sql`, and `trino_admin`

## Download a Parquet file

Use this [user dataset](https://rapid-file-tutorial.s3.us-east-1.amazonaws.com/customers.parquet) provided by team.

## Upload it to the portal

1. Log in to NexusOne.
2. On the NexusOne homepage, navigate to **Ingest > File**.
3. In the File Details section, click **Upload File > Choose file**.

## Add ingest details

Add the following information to the fields:

* **Name**: `parquet`
* **Schema**: `parquet_schema`
* **Table**: `parquet_table`
* **Schedule**: `Run Once`
* **Mode**: `append`
* **Tags**: Don't add any tags

After adding these details, click **Ingest**. Wait for a few minutes until you see a success message appear.

## Monitor job

When you ingest the file, this creates an Airflow job. To monitor the status of the job,
use the following steps:

1. Click **View Jobs** or navigate to the NexusOne homepage and click **Monitor**.
2. Find your job name, `parquet`, in the list, and watch its current status.
3. Wait for a few minutes and refresh your browser until the status changes to `Completed`.

## Visualize your dataset

Use the following steps to visualize your dataset:

1. On the NexusOne homepage, click **Discover** to launch Superset.
2. Hover your mouse over **SQL**, and then select **SQL Lab**.
3. Enter the following command in the query box:

```sql theme={null}
SELECT * FROM parquet_schema.parquet_table
```
