Connect to AlloyDB Data in Airbyte ELT Pipelines

Airbyte empowers users to load your data into any data warehouse, data lake, or database. When combined with CData Connect Cloud, Airbyte users can create Extract, Load, Transform (ELT) pipelines directly from live AlloyDB data. This article illustrates the process of connecting to AlloyDB through Connect Cloud and constructing ELT pipelines for AlloyDB data within Airbyte.

CData Connect Cloud offers a dedicated SQL Server interface for AlloyDB, facilitating data querying without the need for data replication to a native database. With built-in optimized data processing capabilities, CData Connect Cloud efficiently directs all supported SQL operations, including filters and JOINs, straight to AlloyDB. This harnesses server-side processing to swiftly retrieve the desired AlloyDB data.

Configure AlloyDB Connectivity for Airbyte

Connectivity to AlloyDB from Airbyte is made possible through CData Connect Cloud. To work with AlloyDB data from Airbyte, we start by creating and configuring a AlloyDB connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "AlloyDB" from the Add Connection panel
3. Enter the necessary authentication properties to connect to AlloyDB.

   The following connection properties are usually required in order to connect to AlloyDB.

   • Server: The host name or IP of the server hosting the AlloyDB database.
   • User: The user which will be used to authenticate with the AlloyDB server.
   • Password: The password which will be used to authenticate with the AlloyDB server.

   You can also optionally set the following:

   • Database: The database to connect to when connecting to the AlloyDB Server. If this is not set, the user's default database will be used.
   • Port: The port of the server hosting the AlloyDB database. This property is set to 5432 by default.

   Authenticating with Standard Authentication

   Standard authentication (using the user/password combination supplied earlier) is the default form of authentication.

   No further action is required to leverage Standard Authentication to connect.

   Authenticating with pg_hba.conf Auth Schemes

   There are additional methods of authentication available which must be enabled in the pg_hba.conf file on the AlloyDB server.

   Find instructions about authentication setup on the AlloyDB Server here.

   Authenticating with MD5 Authentication

   This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to md5.

   Authenticating with SASL Authentication

   This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to scram-sha-256.

   Authenticating with Kerberos

   The authentication with Kerberos is initiated by AlloyDB Server when the ∏ is trying to connect to it. You should set up Kerberos on the AlloyDB Server to activate this authentication method. Once you have Kerberos authentication set up on the AlloyDB Server, see the Kerberos section of the help documentation for details on how to authenticate with Kerberos.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add AlloyDB Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Connect to AlloyDB from Airbyte

To establish a connection from Airbyte to CData Connect Cloud, follow these steps.

1. Log in to your Airbyte account
2. On the left panel, click Sources, then Add New Source
3. Set Source Type to MSSQL Server to connect the TDS endpoint
4. Set Source Name
5. Set Host URL to tds.cdata.com
6. Set Port to 14333
7. Set Database to the name of the connection you previously configured, e.g. AlloyDB1.
8. Set Username to your Connect Cloud username
9. Set SSL Method to Encrypted (trust server certificate), leave the Replication Method as standard, and set SSH Tunnel Method to No Tunnel
10. (Optional) Set Schema to anything you want to apply to the source
11. Set Password to your Connect Cloud PAT
12. (Optional) Enter any needed JBDC URL Params
13. Click Test and Save to create the data source.

Create ELT Pipelines for AlloyDB Data

To connect AlloyDB data with a new destination, click Connections and then Set Up Connection to connect to your destination. Select the source created above and your desired destination, then allow Airbyte to process. When it is done, your connection is ready for use.
