TL;DR

This can be done by building a data pipeline manually, usually a Python script (you can leverage a tool as Apache Airflow for this). This process can take more than a full week of development. Or it can be done in minutes on Airbyte in three easy steps:

1. set up Snowflake as a source connector (using Auth, or usually an API key)
2. set up S3 as a destination connector
3. define which data you want to transfer and how frequently

You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.

This tutorial’s purpose is to show you how.

What is Snowflake

Snowflake Data Cloud is a cloud-based data warehousing and analytics platform that allows organizations to store, manage, and analyze large amounts of data in a secure and scalable manner.

Prerequisites

1. A Snowflake account to transfer your customer data automatically from.
2. A S3 account.
3. An active Airbyte Cloud account, or you can also choose to use Airbyte Open Source locally. You can follow the instructions to set up Airbyte on your system using docker-compose.

Airbyte is an open-source data integration platform that consolidates and streamlines the process of extracting and loading data from multiple data sources to data warehouses. It offers pre-built connectors, including Snowflake and S3, for seamless data migration.

When using Airbyte to move data from Snowflake to S3, it extracts data from Snowflake using the source connector, converts it into a format S3 can ingest using the provided schema, and then loads it into S3 via the destination connector. This allows businesses to leverage their Snowflake data for advanced analytics and insights within S3, simplifying the ETL process and saving significant time and resources.

Methods to Move Data From Snowflake to s3

• Method 1: Connecting Snowflake to s3 using Airbyte.
• Method 2: Connecting Snowflake to s3 manually.

- Schema: the name of the schema you want to use

6. Click on "Test connection" to make sure that the connection is successful.

7. If the connection is successful, click on "Next" to proceed to the "Configuration" tab.

8. In the "Configuration" tab, select the tables or views that you want to replicate and configure any necessary settings.

9. Click on "Create source" to save your Snowflake Data Cloud source and start replicating data.

Step 2: Set up S3 as a destination connector

1. Log in to your Airbyte account and navigate to the "Destinations" tab on the left-hand side of the screen.

2. Click on the "Add Destination" button and select "S3" from the list of available connectors.

3. Enter your AWS access key ID and secret access key in the appropriate fields. If you don't have these credentials, you can generate them in the AWS console.

4. Choose the AWS region where you want to store your data.

5. Enter the name of the S3 bucket where you want to store your data. If the bucket doesn't exist yet, you can create it in the AWS console.

6. Choose the format in which you want to store your data (e.g. CSV, JSON, Parquet).

7. Configure any additional settings, such as compression or encryption, if desired.

8. Test the connection to ensure that Airbyte can successfully connect to your S3 bucket.

9. Save your settings and start syncing data from your source connectors to your S3 destination.

Step 3: Set up a connection to sync your Snowflake data to S3

Once you've successfully connected Snowflake as a data source and S3 as a destination in Airbyte, you can set up a data pipeline between them with the following steps:

1. Create a new connection: On the Airbyte dashboard, navigate to the 'Connections' tab and click the '+ New Connection' button.
2. Choose your source: Select Snowflake from the dropdown list of your configured sources.
3. Select your destination: Choose S3 from the dropdown list of your configured destinations.
4. Configure your sync: Define the frequency of your data syncs based on your business needs. Airbyte allows both manual and automatic scheduling for your data refreshes.
5. Select the data to sync: Choose the specific Snowflake objects you want to import data from towards S3. You can sync all data or select specific tables and fields.
6. Select the sync mode for your streams: Choose between full refreshes or incremental syncs (with deduplication if you want), and this for all streams or at the stream level. Incremental is only available for streams that have a primary cursor.
7. Test your connection: Click the 'Test Connection' button to make sure that your setup works. If the connection test is successful, save your configuration.
8. Start the sync: If the test passes, click 'Set Up Connection'. Airbyte will start moving data from Snowflake to S3 according to your settings.

Remember, Airbyte keeps your data in sync at the frequency you determine, ensuring your S3 data warehouse is always up-to-date with your Snowflake data.

Method 2: Connecting Snowflake to s3 manually

Prerequisites:

1. Snowflake Account: Access to a Snowflake account with the necessary privileges to read data from the tables/views and to execute data unloading commands.

2. AWS Account: Access to an AWS account with permissions to create and manage S3 buckets and IAM roles/policies.

3. Snowflake Role: Ensure you have a role with the necessary permissions to execute `COPY INTO <location>` commands.

4. AWS S3 Bucket: An S3 bucket where the data will be unloaded. Make sure it's in the same region as your Snowflake account to optimize transfer speeds and minimize costs.

5. AWS IAM User: An IAM user with an access key and secret access key, which will be used to authenticate from Snowflake to S3. This user must have the `s3:PutObject` permission for the target S3 bucket.

Step 1: Configure AWS IAM User and Policy

1. Log in to your AWS Management Console.

2. Navigate to the IAM service.

3. Create a new IAM user with programmatic access.

4. Attach a policy to the IAM user that allows access to the specific S3 bucket. Here's an example policy:

```json

{

    "Version": "2012-10-17",

    "Statement": [

        {

            "Effect": "Allow",

            "Action": "s3:PutObject",

            "Resource": "arn:aws:s3:::your-bucket-name/*"

        }

    ]

}

```

5. Note down the `Access Key ID` and `Secret Access Key` after creating the IAM user.

Step 2: Create an S3 Bucket (if not already created)

1. Navigate to the S3 service in the AWS Management Console.

2. Create a new S3 bucket or use an existing one where you want to store the data.

3. Note the bucket name and the region.

Step 3: Configure Snowflake Storage Integration

1. Log in to your Snowflake account and switch to a role with the necessary privileges.

2. Create a Snowflake storage integration object to delegate authentication to AWS. Replace the placeholders with your specific details:

```sql

CREATE OR REPLACE STORAGE INTEGRATION s3_integration

  TYPE = EXTERNAL_STAGE

  STORAGE_PROVIDER = S3

  ENABLED = TRUE

  STORAGE_AWS_ROLE_ARN = 'arn:aws:iam::<AWS_ACCOUNT_ID>:role/<ROLE_NAME>'

  STORAGE_ALLOWED_LOCATIONS = ('s3://your-bucket-name/');

```

3. Execute the statement and then describe the integration to get the `STORAGE_AWS_IAM_USER_ARN` and `STORAGE_AWS_EXTERNAL_ID`:

```sql

DESC INTEGRATION s3_integration;

```

4. Use the `STORAGE_AWS_IAM_USER_ARN` and `STORAGE_AWS_EXTERNAL_ID` to update the trust relationship of the IAM role in AWS.

Step 4: Create a File Format (if custom formatting is needed)

Create a file format in Snowflake that matches the format of the data you want to unload to S3:

```sql

CREATE OR REPLACE FILE FORMAT my_csv_format

  TYPE = 'CSV'

  FIELD_DELIMITER = ','

  SKIP_HEADER = 1

  NULL_IF = ('\\N');

```

Step 5: Unload Data from Snowflake to S3

1. Use the `COPY INTO` command to unload data from a Snowflake table or view to your S3 bucket. Replace the placeholders with your specific details:

```sql

COPY INTO 's3://your-bucket-name/path/to/folder/'

  FROM your_table_or_view

  STORAGE_INTEGRATION = s3_integration

  FILE_FORMAT = (FORMAT_NAME = my_csv_format)

  OVERWRITE = TRUE

  SINGLE = FALSE;

```

2. Execute the command. Snowflake will unload the data to the specified S3 path.

Step 6: Verify the Data Transfer

1. Go to the AWS S3 console.

2. Navigate to the bucket and the specific path where you unloaded the data.

3. Check that the files have been created and contain the expected data.

Step 7: Clean Up

1. If you created temporary IAM users, roles, or policies, remove them if they are no longer needed.

2. Drop any temporary Snowflake objects that were created for the data transfer.

Notes:

• Ensure that the `STORAGE_INTEGRATION` has been granted to the role you are using in Snowflake.
• The `COPY INTO` command can be customized with additional options, such as `MAX_FILE_SIZE` or `COMPRESSION`, according to your specific needs.
• Monitor the data transfer process and check for any errors or warnings in the Snowflake History tab.
• If you are dealing with sensitive data, consider using encryption options and other security best practices when transferring data to S3.

Use Cases to transfer your Snowflake data to S3

Integrating data from Snowflake to S3 provides several benefits. Here are a few use cases:

1. Advanced Analytics: S3’s powerful data processing capabilities enable you to perform complex queries and data analysis on your Snowflake data, extracting insights that wouldn't be possible within Snowflake alone.
2. Data Consolidation: If you're using multiple other sources along with Snowflake, syncing to S3 allows you to centralize your data for a holistic view of your operations, and to set up a change data capture process so you never have any discrepancies in your data again.
3. Historical Data Analysis: Snowflake has limits on historical data. Syncing data to S3 allows for long-term data retention and analysis of historical trends over time.
4. Data Security and Compliance: S3 provides robust data security features. Syncing Snowflake data to S3 ensures your data is secured and allows for advanced data governance and compliance management.
5. Scalability: S3 can handle large volumes of data without affecting performance, providing an ideal solution for growing businesses with expanding Snowflake data.
6. Data Science and Machine Learning: By having Snowflake data in S3, you can apply machine learning models to your data for predictive analytics, customer segmentation, and more.
7. Reporting and Visualization: While Snowflake provides reporting tools, data visualization tools like Tableau, PowerBI, Looker (Google Data Studio) can connect to S3, providing more advanced business intelligence options. If you have a Snowflake table that needs to be converted to a S3 table, Airbyte can do that automatically.

Wrapping Up

To summarize, this tutorial has shown you how to:

1. Configure a Snowflake account as an Airbyte data source connector.
2. Configure S3 as a data destination connector.
3. Create an Airbyte data pipeline that will automatically be moving data directly from Snowflake to S3 after you set a schedule

With Airbyte, creating data pipelines take minutes, and the data integration possibilities are endless. Airbyte supports the largest catalog of API tools, databases, and files, among other sources. Airbyte's connectors are open-source, so you can add any custom objects to the connector, or even build a new connector from scratch without any local dev environment or any data engineer within 10 minutes with the no-code connector builder.
