Due to the Google BigQuery SDK client limitations, using INSERT is 10x slower than using a Google Cloud Storage bucket, and you may see some failures for big datasets and slow sources (For example, if reading from a source takes more than 10-12 hours). While this is faster to set up initially, we strongly recommend not using this option for anything other than a quick demo. You can use BigQuery's INSERT statement to upload data directly from your source to BigQuery. You can view this setting under the "Configuration" tab of your GCS bucket, in the Encryption type row. We currently do not support buckets using customer-managed encryption keys (CMEK). Your bucket must be encrypted using a Google-managed encryption key (this is the default setting when creating a new bucket). The easiest way to verify if Airbyte is able to connect to your bucket is via the check connection tool in the UI. Make sure your Cloud Storage bucket is accessible from the machine running Airbyte.Grant the Storage Object Admin role to the Google Cloud Service Account.Make sure the bucket does not have a retention policy. Create a Cloud Storage bucket with the Protection Tools set to none or Object versioning.(Recommended) Using a Google Cloud Storage bucket Setup guide Step 1: Set up a data loading method Īlthough you can load data using BigQuery's INSERTS, we highly recommend using a Google Cloud Storage bucket not only for performance and cost but reliability since larger datasets are prone to more failures when using standard inserts. Airbyte does not support normalization for this option at this time. BigQuery (Denormalized): Leverages BigQuery capabilities with Structured and Repeated fields to produce a single "big" table per stream.BigQuery: Produces a normalized output by storing the JSON blob data in _airbyte_raw_* tables and then transforming and normalizing the data into separate tables, potentially exploding nested streams into their own tables if basic normalization is configured.While setting up the connector, you can configure it in the following modes: (Required for Airbyte Cloud Optional for Airbyte Open Source) A Google Cloud Service Account with the BigQuery User and BigQuery Data Editor roles and the Service Account Key in JSON format. For more information, read Introduction to Datasets If you plan on combining the data that Airbyte syncs with data from other datasets in your queries, create the datasets in the same location on Google Cloud. Note: Queries written in BigQuery can only reference datasets in the same physical location. Prerequisites įor Airbyte Open Source users using the Postgres source connector, upgrade your Airbyte platform to version v0.40.0-alpha or newer and upgrade your BigQuery connector to version 1.1.14 or newerĪ Google Cloud project with BigQuery enabled This page guides you through setting up the BigQuery destination connector. There are also a wide range of third-party tools that can be used with BigQuery for data visualization and other tasks.Setting up the BigQuery destination connector involves setting up the data loading method (BigQuery Standard method and Google Cloud Storage bucket) and configuring the BigQuery destination connector using the Airbyte UI. The Google Cloud platform also provides access to a variety of tools from Google and its partners, including Cloud Dataprep to automate the creation of data cleansing pipelines as well as built-in machine learning capabilities to generate insights from large-scale datasets. Like other relational database management systems (RDBMS), BigQuery uses the Structured Query Language or SQL to enable users to quickly store, retrieve, manage, and manipulate data. By using cloud computing to enable rapidly-scalable analysis over petabytes of data, BigQuery is an important software as a service (SaaS) solution for companies looking to harness the power of big data flexibly and cost-effectively. Data warehouses are critical components of data infrastructure required to collect and store data from a variety of sources for use within an organization, but building and maintaining warehouses at the scale necessary for today’s massive datasets can be expensive and time-consuming. BigQuery is a serverless data warehouse that uses the Google Cloud platform.
