EnterpriseDB
The EnterpriseDB connector lets you perform insert, delete, update, and read operations on a EnterpriseDB database.
Before you begin
Before using the EnterpriseDB connector, do the following tasks:
- In your Google Cloud project:
- Grant the roles/connectors.admin IAM role to the user configuring the connector.
- 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. For more information, see Creating a service account.
- Enable the following services:
secretmanager.googleapis.com
(Secret Manager API)connectors.googleapis.com
(Connectors API)
To understand how to enable services, see Enabling services.
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
Configuring the connector requires you to create a connection to your data source (backend system). 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 steps:
- 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.
- Region: Select a location from the drop-down list.
- In the Connection Details section, complete the following:
- Connector: Select EnterpriseDB 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 63 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 EnterpriseDB database.
- Browsable Schemas: This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.
- Allow Prepared Statement: Prepare a query statement before its execution.
- Fetch Result Set Metadata: This field sets whether the provider is getting detailed information about resultset columns from the server.
- Include Table Types: If set to true, the provider will query for the types of individual tables and views.
- Visibility: Visibility restrictions used to filter exposed metadata for tables with privileges granted to them for current user.'SELECT,INSERT' filter is restricting metatdata visibility only for those tables which may be accessed by current user for SELECT and INSERT operations. Supported privilege values are SELECT, INSERT, UPDATE, DELETE, REFERENCES.
- UseSSL: This field sets whether SSL is enabled.
- 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.
- Select Host address from the list to specify the hostname or IP address of the destination.
- If you want to establish a private connection to your backend systems, select Endpoint attachment from the list, and then select the required endpoint attachment from the Endpoint Attachment list.
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.
- Destination Type: Select a Destination Type.
-
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 EnterpriseDB connection:
- Username and password
- Click NEXT.
To understand how to configure these authentication types, see Configure authentication.
- Select an Authentication type and enter the relevant details.
- 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.
Use terraform to create connections
You can use the Terraform resource to create a new connection.To learn how to apply or remove a Terraform configuration, see Basic Terraform commands.
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 EnterpriseDB database. |
browsable_schemas | STRING | False | This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC. |
allow_prepared_statement | BOOLEAN | False | Prepare a query statement before its execution. |
fetch_result_set_metadata | BOOLEAN | False | This field sets whether the provider is getting detailed information about resultset columns from the server. |
include_table_types | BOOLEAN | False | If set to true, the provider will query for the types of individual tables and views. |
use_ssl | BOOLEAN | False | This field sets whether SSL is enabled. |
visibility | STRING | False | Visibility restrictions used to filter exposed metadata for tables with privileges granted to them for current user.'SELECT,INSERT' filter is restricting metatdata visibility only for those tables which may be accessed by current user for SELECT and INSERT operations. Supported privilege values are SELECT, INSERT, UPDATE, DELETE, REFERENCES. |
Use the EnterpriseDB 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.
