“Airbyte helped us accelerate our progress by years, compared to our competitors. We don’t need to worry about connectors and focus on creating value for our users instead of building infrastructure. That’s priceless. The time and energy saved allows us to disrupt and grow faster.”

Rupak Patel
"With Airbyte, we could just push a few buttons, allow API access, and bring all the data into Google BigQuery. By blending all the different marketing data sources, we can gain valuable insights."
How to Sync to Manually
Step 1: Understand Your Data Source
Begin by thoroughly understanding the structure and format of the data in your merge data source. Identify the types of data (e.g., CSV, JSON, SQL databases) and ensure you have the necessary permissions to access and extract this data. This foundational knowledge is crucial for planning the data transfer process effectively.
Step 2: Export Data from the Source
Export the data from your merge source into a format that is compatible with Databricks ingestion methods. Common formats include CSV, JSON, or Parquet files. Use built-in export functionalities provided by your data source to generate these files, ensuring that the export process covers all relevant data fields and respects any data formatting or transformation requirements.
Step 3: Prepare Your Databricks Environment
Set up your Databricks environment by creating a new workspace or using an existing one. Ensure you have access to a Databricks Lakehouse and the necessary permissions to create databases and tables. Configure your cluster settings appropriately, taking into consideration the size and complexity of the data you will be importing.
Step 4: Transfer Files to a Storage Solution
Move the exported data files into a cloud storage solution that Databricks can access, such as AWS S3, Azure Blob Storage, or Google Cloud Storage. Use command-line tools or cloud service web interfaces to upload your files. Ensure that the files are organized and named clearly to facilitate easy access and management during the ingestion process.
Step 5: Mount Storage in Databricks
In Databricks, use the Databricks File System (DBFS) to mount the cloud storage solution where your data files reside. This step involves writing a few lines of code in a Databricks notebook to establish a connection between your Databricks environment and the cloud storage. Verify that the mount is successful by listing the files to ensure they are accessible.
Step 6: Create Schema and Tables in Databricks
Define the schema for your data based on the structure of the exported files. Use Databricks SQL or PySpark to create tables within your Databricks Lakehouse. Ensure that the data types and structures match those of the source data to prevent issues during data import. This step sets up the necessary data structures to receive incoming data.
Step 7: Load Data into Databricks Lakehouse
Use Databricks notebooks to read the data files from the mounted storage and load them into the tables you created in the Lakehouse. Employ Spark's powerful data processing capabilities to handle data transformations and load operations efficiently. Verify the loaded data for accuracy and completeness by running queries and checking against expected results.
By following these steps, you can successfully move data from a merge data source to a Databricks Lakehouse without relying on third-party connectors or integrations.
