This tutorial demonstrates how to configure Pixeltable to use
[Tigris](https://tigrisdata.com) for storage. This lets you store
unlimited amounts of images in Tigris’ global data plane, allowing your
images to load fast everywhere.
## Prerequisites
* A Tigris account, bucket, and access keypair
([https://storage.new](https://storage.new))
## Important notes
* Tigris usage may incur costs based on your plan.
* Be mindful of sensitive data and consider security measures when
integrating with external services.
First you need to install required libraries and enter a Tigris access
keypair obtained via the Tigris Admin Console.
## Set up environment
First, let’s install Pixeltable:
```python theme={null}
%pip install -qU pixeltable boto3 datasets
```
## Configure authentication
These steps will have you enter in your Tigris credentials:
```python theme={null}
import os
from getpass import getpass
os.environ['AWS_ACCESS_KEY_ID'] = getpass('Tigris access key ID')
os.environ['AWS_SECRET_ACCESS_KEY'] = getpass('Tigris secret access key')
bucket_name = getpass('Tigris bucket name')
os.environ['AWS_ENDPOINT_URL_S3'] = 'https://t3.storage.dev'
os.environ['AWS_REGION'] = 'auto'
os.environ['PIXELTABLE_INPUT_MEDIA_DEST'] = f's3://{bucket_name}/input/'
os.environ['PIXELTABLE_OUTPUT_MEDIA_DEST'] = f's3://{bucket_name}/output/'
```
## Create a table for images
Now let’s create a table that will contain images from the
[XeIaso/botw-screenshots-captioned](https://huggingface.co/datasets/XeIaso/botw-screenshots-captioned)
dataset:
```python theme={null}
import pixeltable as pxt
from datasets import load_dataset
# Create directory for this demo
pxt.drop_dir('tigris', force=True)
pxt.create_dir('tigris', if_exists='replace')
# Load the dataset
ds = load_dataset('XeIaso/botw-screenshots-captioned')
# Import it to pixeltable with the name screenshots
pxt.drop_table('tigris/screenshots', force=True)
screenshots = pxt.create_table(
'tigris/screenshots', source=ds, if_exists='replace'
)
```
Created directory 'tigris'.
Created table 'screenshots'.
Inserting rows into \`screenshots\`: 100 rows \[00:01, 51.72 rows/s]
Inserting rows into \`screenshots\`: 100 rows \[00:01, 55.57 rows/s]
Inserting rows into \`screenshots\`: 100 rows \[00:01, 52.74 rows/s]
Inserting rows into \`screenshots\`: 100 rows \[00:02, 33.96 rows/s]
Inserting rows into \`screenshots\`: 100 rows \[00:02, 42.64 rows/s]
Inserting rows into \`screenshots\`: 100 rows \[00:02, 39.65 rows/s]
Inserting rows into \`screenshots\`: 100 rows \[00:02, 47.36 rows/s]
Inserting rows into \`screenshots\`: 28 rows \[00:00, 6786.12 rows/s]
Inserted 728 rows with 0 errors.
Once the import is done, you can create thumbnails with a [computed
column](/tutorials/computed-columns):
```python theme={null}
# Add a computed column for thumbnails
# Uses output_media_dest by default, or specify a custom destination
screenshots.add_computed_column(
thumbnail=screenshots.image.resize((256, 256)),
destination=f's3://{bucket_name}/botw-screenshots/thumbnails/',
)
```
Added 728 column values with 0 errors.
728 rows updated, 728 values computed.
And then inspect that with the `collect` method:
```python theme={null}
results = screenshots.limit(1).collect()
results
```
## Getting URLs for your files
When your files are in object storage, you can get URLs that point
directly to them. These URLs work in HTML, APIs, or any application you
need to serve media with. Fetch them with the `.fileurl` property:
```python theme={null}
screenshots.select(
image=screenshots.image,
image_url=screenshots.image.fileurl,
thumbnail=screenshots.thumbnail,
thumbnail_url=screenshots.thumbnail.fileurl,
).limit(1).collect()
```
## Generating Presigned URLs
For private buckets or when you need time-limited access to files, use
presigned URLs. These are temporary, authenticated URLs that allow
anyone to access your files for a limited time without needing
credentials.
Use the `presigned_url` function from `pixeltable.functions.net`:
```python theme={null}
from pixeltable.functions import net
# Generate presigned URLs with 1-hour expiration (3600 seconds)
screenshots.select(
image=screenshots.image,
image_url=screenshots.image.fileurl,
image_presigned=net.presigned_url(screenshots.image.fileurl, 3600),
thumbnail=screenshots.thumbnail,
thumbnail_url=screenshots.thumbnail.fileurl,
thumbnail_presigned=net.presigned_url(
screenshots.thumbnail.fileurl, 3600
),
).limit(1).collect()
```
### Common expiration times
## What you learned
* When you configure Pixeltable to use Tigris to store images, adding
images transparently uploads them into Tigris for global
distribution.
* You can override where images are stored in Tigris using the
`destination=` kwarg when creating computed columns.
* Use the `.fileurl` property in queries to get URLs for your stored
files.
* Use `net.presigned_url()` to generate time-limited, authenticated
URLs for private bucket access.
Pixeltable handles everything else for you.
