Predictable, straightforward pricing model that simplified budgeting and significantly reduced overall spend

Chase Zieman

“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: Set Up Google Cloud SDK
Before you begin, ensure that you have the Google Cloud SDK installed and configured on your local machine. This tool allows you to interact with Google Cloud services from the command line. Download and install it from the [Google Cloud SDK page](https://cloud.google.com/sdk/docs/install), and then initialize it by running `gcloud init` to set up authentication and configuration.
Step 2: Create a BigQuery Dataset and Table
Log into your Google Cloud Console, navigate to BigQuery, and create a new dataset if you don�t already have one. Within this dataset, define a table where your data will be stored. Specify the schema for the table, which includes defining the fields and their data types that match the structure of your data.
Step 3: Prepare Your Data for Upload
Convert your iterable data into a format that BigQuery can accept, such as CSV or JSON. This can be done programmatically. For example, if you have a list of dictionaries in Python, you can convert it to a JSON Lines file. Each line in the file represents a record in JSON format.
Step 4: Upload Data to Google Cloud Storage
Before you can load data into BigQuery, upload the prepared file to Google Cloud Storage (GCS), which acts as an intermediary storage. Use the `gsutil` command-line tool (included with the Google Cloud SDK) to upload your file. For example:
```bash
gsutil cp your_data_file.json gs://your-bucket-name/
```
Ensure that you have created a Google Cloud Storage bucket prior to this step.
Step 5: Load Data from GCS to BigQuery
Use the `bq` command-line tool to load data from GCS into your BigQuery table. You need to specify the dataset, table, and the path to your data file in GCS. Here is an example command:
```bash
bq load --source_format=NEWLINE_DELIMITED_JSON your_dataset.your_table gs://your-bucket-name/your_data_file.json
```
Adjust the `--source_format` flag based on the format of your data file.
Step 6: Verify Data Load in BigQuery
After loading the data, confirm that the data has been transferred successfully by querying the table in the BigQuery web interface or using the `bq` command-line tool. You can run simple SQL queries to check if the records are correctly inserted.
Step 7: Automate the Process with a Script
To streamline future data uploads, consider writing a script that automates the entire process. This script should handle data preparation, upload to GCS, and loading into BigQuery. Use a language like Python or Bash and make use of the Google Cloud SDK command-line tools to execute each step programmatically.
By following these steps, you can efficiently transfer data from an iterable to BigQuery without relying on third-party connectors or integrations, leveraging only Google Cloud's native tools.
