Building your pipeline or Using Airbyte

Airbyte is the only open source solution empowering data teams  to meet all their growing custom business demands in the new AI era.

Building in-house pipelines
Bespoke pipelines are:
  • Inconsistent and inaccurate data
  • Laborious and expensive
  • Brittle and inflexible
Furthermore, you will need to build and maintain Y x Z pipelines with Y sources and Z destinations to cover all your needs.
After Airbyte
Airbyte connections are:
  • Reliable and accurate
  • Extensible and scalable for all your needs
  • Deployed and governed your way
All your pipelines in minutes, however custom they are, thanks to Airbyte’s connector marketplace and AI Connector Builder.

Start syncing with Airbyte in 3 easy steps within 10 minutes

Set up a n8n connector in Airbyte

Connect to n8n or one of 400+ pre-built or 10,000+ custom connectors through simple account authentication.

Set up Weaviate for your extracted n8n data

Select Weaviate where you want to import data from your n8n source to. You can also choose other cloud data warehouses, databases, data lakes, vector databases, or any other supported Airbyte destinations.

Configure the n8n to Weaviate in Airbyte

This includes selecting the data you want to extract - streams and columns -, the sync frequency, where in the destination you want that data to be loaded.

How to Sync n8n to Weaviate Manually

Begin by accessing your n8n instance and creating a new workflow. This will serve as the automated process to extract and structure your data. Add the necessary nodes to pull data from the source within n8n. Ensure you have the data ready in a JSON format to be compatible with Weaviate's API.

Add an HTTP Request node to your n8n workflow. This node will be responsible for sending data to Weaviate. Set the method to POST, as you'll be sending data to Weaviate, and configure the URL to point to your Weaviate instance (e.g., `http://your-weaviate-instance/v1/objects`).

Before sending data, ensure it is structured according to Weaviate's requirements. Weaviate expects data in a specific JSON format, typically including fields like `class`, `properties`, and `id`. Use n8n's Function Node to format your data appropriately, transforming any necessary fields to match Weaviate's schema.

If your Weaviate instance requires authentication, you must include the necessary credentials. In the HTTP Request node, set up the appropriate headers for authentication. This might include an API key or a token, which can be set in the Headers parameter of the HTTP Request node.

With your HTTP Request node configured, execute the workflow in n8n to send the data. Monitor the response from Weaviate to ensure that the data is being received correctly. If there are any errors, use the response to diagnose and resolve issues with data formatting or authentication.

After sending data, verify that it has been correctly stored in Weaviate. Access your Weaviate instance and use the Weaviate console or API to query the data. Check that all fields are correctly populated and that the data structure aligns with the intended schema.

Once verified, you can automate the n8n workflow to run at desired intervals, ensuring continuous data transfer. Use n8n's Trigger Nodes, like Cron or Webhook, to schedule the workflow based on your requirements, ensuring data between n8n and Weaviate remains synchronized over time.
With these steps, you can effectively move data from n8n to Weaviate without relying on third-party connectors or integrations.

ETL, an acronym for Extract, Transform, Load, is a vital data integration process. It involves extracting data from diverse sources, transforming it into a usable format, and loading it into a database, data warehouse or data lake. This process enables meaningful data analysis, enhancing business intelligence.

N8n is a free and open fair-code distributed node-based Workflow Automation Tool. You can self-host n8n, easily extend it, and even you can use it. n8n is an extendable workflow automation tool that enables you to connect anything to everything via its open, fair-code model. Berlin, Germany n8n. With a fair-code distribution model, n8n will always have visible source code, be available to self-host, and allow you to add your own custom functions, logic, and apps.

N8n's API provides access to a wide range of data types, including:  

1. Workflow data: This includes information about the workflows created in n8n, such as their names, descriptions, and trigger events.  
2. Node data: This includes data related to the individual nodes used in workflows, such as their names, types, and configurations.  
3. Execution data: This includes information about the execution of workflows, such as the start and end times, the status of each node, and any errors encountered.  
4. Credentials data: This includes data related to the credentials used to authenticate with external services, such as API keys and access tokens.  
5. Workflow run data: This includes data related to the runs of individual workflows, such as the input and output data, the status of each node, and any errors encountered.  
6. Node run data: This includes data related to the runs of individual nodes within workflows, such as the input and output data, the status of the node, and any errors encountered.  

Overall, n8n's API provides access to a comprehensive set of data types that can be used to monitor and manage workflows, troubleshoot issues, and optimize performance.

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 N8n to Weaviate as a source connector (using Auth, or usually an API key)
2. Choose a destination (more than 50 available destination databases, data warehouses or lakes) to sync data too and set it up as a destination connector
3. Define which data you want to transfer from N8n to Weaviate and how frequently
You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud. 

ELT, standing for Extract, Load, Transform, is a modern take on the traditional ETL data integration process. In ELT, data is first extracted from various sources, loaded directly into a data warehouse, and then transformed. This approach enhances data processing speed, analytical flexibility and autonomy.

ETL and ELT are critical data integration strategies with key differences. ETL (Extract, Transform, Load) transforms data before loading, ideal for structured data. In contrast, ELT (Extract, Load, Transform) loads data before transformation, perfect for processing large, diverse data sets in modern data warehouses. ELT is becoming the new standard as it offers a lot more flexibility and autonomy to data analysts.
