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

What is DynamoDB

Prerequisites

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

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

Step 1: Set up BigQuery as a source connector

Step 2: Set up DynamoDB as a destination connector

Step 3: Set up a connection to sync your BigQuery data to DynamoDB

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

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

Use Cases to transfer your BigQuery data to DynamoDB

Integrating data from BigQuery to DynamoDB provides several benefits. Here are a few use cases:

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

Wrapping Up

To summarize, this tutorial has shown you how to:

1. Configure a BigQuery account as an Airbyte data source connector.
2. Configure DynamoDB as a data destination connector.
3. Create an Airbyte data pipeline that will automatically be moving data directly from BigQuery to DynamoDB after you set a schedule
