How to load data from SFTP to Weaviate

Learn how to use Airbyte to synchronize your SFTP data into Weaviate within minutes.

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 SFTP as a source connector (using Auth, or usually an API key)
  2. set up Weaviate 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 SFTP

SFTP (Secure File Transfer Protocol) is a secure way to transfer files between two computers over the internet. It uses encryption to protect the data being transferred, making it more secure than traditional FTP (File Transfer Protocol). SFTP is commonly used by businesses and organizations to transfer sensitive data such as financial information, medical records, and personal data. It requires authentication using a username and password or public key authentication, ensuring that only authorized users can access the files. SFTP is also platform-independent, meaning it can be used on any operating system, making it a versatile and reliable option for secure file transfers.

What is Weaviate

Weaviate is an open-source, cloud-native, real-time vector search engine that allows developers to build intelligent applications with natural language processing (NLP) capabilities. It uses machine learning algorithms to understand the meaning of unstructured data and provides a semantic search engine that can retrieve relevant information from large datasets. Weaviate can be used to build chatbots, recommendation systems, and other intelligent applications that require NLP capabilities. It is designed to be scalable, flexible, and easy to use, with a RESTful API that allows developers to integrate it into their applications quickly. Weaviate is built on top of Kubernetes and can be deployed on-premises or in the cloud.

Prerequisites

  1. A SFTP account to transfer your customer data automatically from.
  2. A Weaviate 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 SFTP and Weaviate, for seamless data migration.

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

Step 1: Set up SFTP as a source connector

1. Open the Airbyte platform and navigate to the "Sources" tab on the left-hand side of the screen.
2. Click on the "Create a new connection" button and select "SFTP" as the source connector.
3. Enter a name for the connection and click "Next".
4. In the "Connection Configuration" section, enter the hostname or IP address of the SFTP server, as well as the port number (usually 22).
5. Enter the username and password for the SFTP server in the "Authentication" section.
6. If your SFTP server requires a private key for authentication, select the "Private Key" option and enter the path to the key file.
7. In the "Advanced" section, you can specify additional options such as the path to the remote directory and the file pattern to use for selecting files.
8. Click "Test" to verify that the connection is working correctly.
9. If the test is successful, click "Create" to save the connection and start syncing data from the SFTP server.

Step 2: Set up Weaviate as a destination connector

1. First, navigate to the Weaviate destination connector on Airbyte's website.
2. Click on the "Get Started" button to begin the setup process.
3. Enter the required credentials for your Weaviate instance, including the URL, API key, and schema name.
4. Test the connection to ensure that the credentials are correct and the connection is successful.
5. Choose the tables or collections that you want to sync from your source connector to Weaviate.
6. Map the fields from your source connector to the corresponding fields in Weaviate.
7. Set up any necessary transformations or filters to ensure that the data is formatted correctly for Weaviate.
8. Schedule the sync to run at regular intervals or manually trigger it as needed.
9. Monitor the sync to ensure that the data is being transferred correctly and troubleshoot any issues that arise.
10. Once the sync is complete, verify that the data has been successfully transferred to Weaviate.

Step 3: Set up a connection to sync your SFTP data to Weaviate

Once you've successfully connected SFTP as a data source and Weaviate 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 SFTP from the dropdown list of your configured sources.
  3. Select your destination: Choose Weaviate 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 SFTP objects you want to import data from towards Weaviate. 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 SFTP to Weaviate according to your settings.

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

Use Cases to transfer your SFTP data to Weaviate

Integrating data from SFTP to Weaviate provides several benefits. Here are a few use cases:

  1. Advanced Analytics: Weaviate’s powerful data processing capabilities enable you to perform complex queries and data analysis on your SFTP data, extracting insights that wouldn't be possible within SFTP alone.
  2. Data Consolidation: If you're using multiple other sources along with SFTP, syncing to Weaviate 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: SFTP has limits on historical data. Syncing data to Weaviate allows for long-term data retention and analysis of historical trends over time.
  4. Data Security and Compliance: Weaviate provides robust data security features. Syncing SFTP data to Weaviate ensures your data is secured and allows for advanced data governance and compliance management.
  5. Scalability: Weaviate can handle large volumes of data without affecting performance, providing an ideal solution for growing businesses with expanding SFTP data.
  6. Data Science and Machine Learning: By having SFTP data in Weaviate, you can apply machine learning models to your data for predictive analytics, customer segmentation, and more.
  7. Reporting and Visualization: While SFTP provides reporting tools, data visualization tools like Tableau, PowerBI, Looker (Google Data Studio) can connect to Weaviate, providing more advanced business intelligence options. If you have a SFTP table that needs to be converted to a Weaviate table, Airbyte can do that automatically.

Wrapping Up

To summarize, this tutorial has shown you how to:

  1. Configure a SFTP account as an Airbyte data source connector.
  2. Configure Weaviate as a data destination connector.
