Grant the following IAM roles to the service account that you want to use for the connector:
roles/secretmanager.viewer
roles/secretmanager.secretAccessor
A service account is a special type of Google account intended to represent a non-human
user that needs to authenticate and be authorized to access data in Google APIs.
If you don't have a service account, you must create a service account. The connector and the service account must belong to the same project. For more
information, see
Creating a service account.
If these services or permissions have not been enabled for your project previously, you are prompted to enable them
when configuring the connector.
Configure the connector
A connection is specific to a data source. It
means that if you have many data sources, you must create a separate connection
for each data source. To create a connection, do the following:
In the Cloud console, go to the Integration Connectors > Connections page
and then select or create a Google Cloud project.
Click + CREATE NEW to open the Create Connection page.
In the Location section, choose the location for the connection.
Region: Select a location from the drop-down list.
For the list of all the supported regions, see Locations.
Click NEXT.
In the Connection Details section, complete the following:
Connector: Select MariaDB from the drop down list of available Connectors.
Connector version: Select the Connector version from the drop down list of available versions.
In the Connection Name field, enter a name for the Connection instance.
Connection names must meet the following criteria:
Connection names can use letters, numbers, or hyphens.
Letters must be lower-case.
Connection names must begin with a letter and end with a letter or number.
Connection names cannot exceed 49 characters.
Optionally, enter a Description for the connection instance.
Optionally, enable Cloud logging,
and then select a log level. By default, the log level is set to Error.
Service Account: Select a service account that has the required roles.
Optionally, configure the Connection node settings:
Minimum number of nodes: Enter the minimum number of connection nodes.
Maximum number of nodes: Enter the maximum number of connection nodes.
A node is a unit (or replica) of a connection that processes transactions.
More nodes are required to process more transactions for a connection and conversely,
fewer nodes are required to process fewer transactions.
To understand how the nodes affect your connector pricing, see
Pricing for connection nodes. If you don't enter any values, by default
the minimum nodes are set to 2 (for better availability) and the maximum nodes are set to 50.
Database: The name of the MariaDB database.
Allow User Variables: When set to True, user variables (prefixed by an @) can be used in SQL queries.
Zero Dates To Null: Whether or not to return Date and DateTime values consisting of all zeros as NULL.
Optionally, click + ADD LABEL to add a label to the Connection in the form of a key/value pair.
Click NEXT.
In the Destinations section, enter details of the remote host (backend system) you want to connect to.
Destination Type: Select a Destination Type.
To specify the destination hostname or IP address, select Host address and
enter the address in the Host 1 field.
To establish a private connection, select Host Address and add the endpoint attachment created for the SAP Gateway using the HTTPS protocol.
If you want to establish a public connection to your backend systems with additional security, you can
consider configuring static outbound
IP addresses for your connections, and then configure
your firewall rules to allowlist only the specific static IP addresses.
To enter additional destinations, click +ADD DESTINATION.
Click NEXT.
In the Authentication section, enter the authentication details.
Select an Authentication type and enter the relevant details.
The following authentication types are supported by the MariaDB connection:
Review: Review your connection and authentication details.
Click Create.
Configure authentication
Enter the details based on the authentication you want to use.
Username and password
Username: Username for connector
Password: Secret Manager Secret containing the password associated with the connector.
Entities, operations, and actions
All the Integration Connectors provide a layer of abstraction for the objects of
the connected application. You can access an application's objects only through
this abstraction. The abstraction is exposed to you as entities, operations, and actions.
Entity: An entity can be thought of as an object, or a collection of properties, in the
connected application or service. The definition of an entity differs from a connector to a
connector. For example, in a database connector, tables are the entities, in a
file server connector, folders are the entities, and in a messaging system connector,
queues are the entities.
However, it is possible that a connector doesn't support or have any entities, in which case the
Entities list will be empty.
Operation: An operation is the activity that you can perform on an entity. You can perform
any of the following operations on an entity:
Selecting an entity from the available list, generates a list of
operations available for the entity. For a detailed description of the operations, see the Connectors task's
entity operations.
However, if a connector doesn't support any of the entity operations, such unsupported
operations aren't listed in the Operations list.
Action: An action is a first class function that is made available to the integration
through the connector interface. An action lets you make changes to an entity or entities, and
vary from connector to connector. Normally, an action will have some input parameters, and an output
parameter. However, it is possible
that a connector doesn't support any action, in which case the Actions list will be empty.
System limitations
The MariaDB connector can process 10 transaction per second,
per node,
and throttles any transactions
beyond this limit.
By default, Integration Connectors allocates 2 nodes (for better availability) for a connection.
For information on the limits applicable to Integration Connectors, see Limits.
To view a sample terraform template for connection creation, see sample template.
When creating this connection by using Terraform, you must set the following variables in your Terraform configuration file:
Parameter name
Data type
Required
Description
database
STRING
True
The name of the MariaDB database.
allow_user_variables
BOOLEAN
False
When set to True, user variables (prefixed by an @) can be used in SQL queries.
zero_dates_to_null
BOOLEAN
False
Whether or not to return Date and DateTime values consisting of all zeros as NULL.
Use the MariaDB connection in an integration
After you create the connection, it becomes available in both
Apigee Integration and Application Integration. You can use the connection
in an integration through the Connectors task.
To understand how to create and use the Connectors task in Apigee Integration, see Connectors task.
To understand how to create and use the Connectors task in Application Integration, see Connectors task.
