“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: Export Data from Dremio
Begin by exporting the data you wish to transfer from Dremio. This can be done by running a SQL query in Dremio's SQL Editor and exporting the result set. Save the exported data in a CSV or JSON format, as these are commonly used and supported by BigQuery.
Step 2: Prepare Data Locally
Once the data is exported, check the file for any issues or formatting that may not comply with BigQuery's requirements. Ensure that the data types are consistent and that there are no missing or corrupt entries. This step is crucial to avoid errors during the import process.
Step 3: Upload Data to Google Cloud Storage (GCS)
Next, upload the cleaned and prepared data file to Google Cloud Storage. Google Cloud Storage acts as an intermediary storage location from which BigQuery can easily access the data. Use the Google Cloud Console or the `gsutil` command-line tool to upload your file to a specified bucket.
Step 4: Configure Access Permissions
Ensure the necessary permissions are set on your Google Cloud Storage bucket. The service account used by BigQuery must have access to read the data from the bucket. Adjust the permissions in the Google Cloud Console if necessary to allow BigQuery to access the file.
Step 5: Create a BigQuery Dataset
In the BigQuery console, create a new dataset where your data will reside. A dataset is essentially a container for your tables and provides a way to organize and manage them. This step is necessary before you can import data into BigQuery.
Step 6: Load Data into BigQuery
Use the BigQuery web UI, the `bq` command-line tool, or a SQL query in the BigQuery console to load the data from Google Cloud Storage into a BigQuery table. Specify the data format (CSV or JSON), the schema, and the location of the file in Google Cloud Storage. If using the command-line tool, a typical command might look like this:
```
bq load --source_format=CSV [PROJECT_ID]:[DATASET].[TABLE] gs://[BUCKET]/[FILE].csv [SCHEMA]
```
Step 7: Verify and Validate Data in BigQuery
After the import process is complete, verify that the data has been imported correctly. Run queries in the BigQuery console to check the integrity and accuracy of the data. Ensure that all records are present and that there are no discrepancies. This step ensures the successful migration of data from Dremio to BigQuery.
By following these steps, you can successfully transfer data from Dremio to BigQuery without the need for third-party connectors or integrations.
