Using Pinecone Vector Database with IBM App Connect Enterprise

Pinecone Vector Database is a purpose-built platform for indexing and searching dense vectors. It supports use cases like semantic search, recommendation systems, and AI-powered data analysis.

The following steps show you how to connect to a Pinecone Vector Database account and configure a Pinecone Vector Database Request node by using connector discovery.

1. In the IBM App Connect Enterprise Toolkit, create a flow that contains a Pinecone Vector Database Request node.
2. Select the Pinecone Vector Database Request node in the flow to show the node properties in the editor.
3. On the Basic tab, click Launch Connector Discovery.
   A panel is displayed in which you specify the name of the policy project and vault details to be used during connector discovery.
4. Specify the details of the policy project and vault to be used during connector discovery:
   1. In the Policy Project field, specify the policy project that is used to store the policies that are created during connector discovery.
      Alternatively, you can create a new policy project by clicking New and then specifying the name of the new policy project. Then click Finish.
   2. Specify the vault to be used during connector discovery. By default, credentials that are used during connector discovery are stored in an external directory vault, which is an App Connect Enterprise vault that can be used by any integration server. Alternatively, you can store the credentials in an integration server vault, which is created in the integration server's work directory and can be used only by that specific integration server.
      To specify the vault to be used for storing the credentials, complete the steps in the Using the Connector Discovery wizard section of one of the following topics:

      • Configuring an external directory vault
      • Configuring an integration server vault
   3. In the Vault key field, enter the vault key that is used to access the credentials stored in the vault. The vault key must be at least 8 characters in length.
   4. Optional: By default, the specified vault location and vault key are saved as preferences in the Toolkit so that the values are preset when you launch Connector Discovery. If you do not want the preferences to be saved, deselect Save in vault preferences.
5. Click Launch Discovery to start the Connector Discovery wizard for the Pinecone Vector Database connector.
   The Connector Discovery window is displayed. If existing Pinecone Vector Database connections (accounts) are available, a list of those connections is displayed. If there are no existing connections, the status of the Pinecone Vector Database connector is shown as Not connected.
   • If one or more Pinecone Vector Database connections (accounts) are available, complete the following steps:
     1. Select the connection (account) that you want to use by clicking it.
     2. Click the required object type and then select the action that you want to perform on the object. For example, to retrieve all indexes from Pinecone Vector Database, click Indexes and then Retrieve all indexes.
   • If there are no existing connections (accounts), complete the following steps:
     1. Click the required object type and then select the action that you want to perform on that object. For example, to retrieve all indexes from Pinecone Vector Database, click Indexes and then Retrieve all indexes.
     2. Click Connect.
        A window is displayed in which you enter the connection details for your Pinecone Vector Database account. Enter the following information in the connector wizard:

        • Server URL: Specify the URL for the API server that makes runtime calls.
        • API key: The API key used to access Pinecone Vector Database
        • Allow self-signed certificates: Set to true or false. Set to true if you want to be able to accept self-signed certificates that are trusted and used only in a nonproduction environment. The default is false.
        • Override server URL: Required if you want to connect to an endpoint in a private network by using the private network client, or if you want to override the server URL. Specify an override value for the host and port for the connector in the format <http or https>://<host_name>:<port>. If you are not using the private network client or do not require an override, leave this field blank.
     3. Click Connect.

     For more information about identifying these connection details, see Obtaining connection values for Pinecone Vector Database in the IBM App Connect Enterprise as a Service documentation.

6. Set the required connector properties in the wizard.
   You can also set properties that specify the maximum number of records to retrieve and the action to be taken if that limit is exceeded.
7. When you have finished specifying the properties in the Connector Discovery wizard, click Save.
   The credential that is used for connecting to Pinecone Vector Database is stored in the vault, and the other connection details are saved in the Pinecone Vector Database policy. The values of the properties that you set in the wizard are returned to the Pinecone Vector Database Request node in the IBM App Connect Enterprise Toolkit.
8. When you finish discovery and save the property values, exit the Connector Discovery wizard by clicking the X in the upper-right corner of the window or by pressing Alt+F4.
9. Return to editing the Pinecone Vector Database Request node in the IBM App Connect Enterprise Toolkit.
   The connector properties that were set in the Connector Discovery wizard (in step 6) are now visible on the Pinecone Vector Database Request node in the property editor. The Basic tab shows the values of the Action and Object properties that you set in the wizard. For example, if you selected Indexes > Retrieve all indexes in the wizard, the following properties are visible on the Basic tab of the node:

   • Action - getIndexes
   • Object - Indexes

   The values of the Action and Object properties are displayed in read-only format. If you want to change these values, you can do so by clicking Launch Connector Discovery again and setting new values in the Connector Discovery wizard.

   The Schema base name property specifies the base name of the schema files that describe the format of the request and response messages that are sent and received from the Pinecone Vector Database connector. The schema base name is set automatically the first time that you run discovery for the node, and it is based on the current flow name and node name. If you set this property manually before you run discovery for the first time, the value that you set is used. If you rename the schemas after discovery, you must edit this property so that it matches the schema base name that is used by the renamed schemas in the project. If you change this property after discovery, you must either rename the schema names to match or run discovery again.

   Depending on the action that was selected during discovery, the Connector Discovery wizard generates either a request schema and a response schema, or a response schema only. A request schema is generated only if the selected action and object require a request message. The generated request schema is used for validation of the request message. If the action was RETRIEVE or DELETE, only the response schema is returned by the connector.

   The generated schema files are added to the project and can be used by a Mapping node for transforming input or output data. The full filename of the schema is derived from the schema base name (such as gen/MyMessageFlow.Pinecone_Vector_Database_Request), suffixed with either response.schema.json or request.schema.json. You can open the schema by clicking Open request schema or Open response schema.

10. Check that the property settings on the Pinecone Vector Database Request node are correct and then save the message flow.
11. On the Connection tab of the Pinecone Vector Database Request node, the Policy property shows the name of the policy that contains the details of the security identity to be used for the connection. The policy has a type of Pinecone Vector Database.
    For more information, see Pinecone Vector Database policy.
12. Optional: Set the Timeout property on the Connection tab to specify the time (in seconds) that the node waits for Pinecone Vector Database to process the operation.
13. The Filter tab of the Pinecone Vector Database Request node contains properties that control how the message flow selects data. The initial values of these properties are taken from the property values that were set for the Pinecone Vector Database connector in the Connector Discovery wizard, including the filter options properties and any conditions that were specified (as described in step 6). Then, if you return to the Connector Discovery wizard and change the values of any properties (by adding new conditions, for example) those updates are reflected in the properties set on the node.

    The Filter Options properties control which objects are to be operated upon when the Pinecone Vector Database Request node executes. The Filter Limit properties control the maximum number of items to be retrieved and the action to be taken if the limit is exceeded.

    You can modify the values by clicking Edit next to the value that you want to modify in the Filter Options section, and by changing the property values that have been set in the Filter Limit section.

    The property values can be either text values or ESQL or XPATH expressions that are resolved from the contents of the message that is passed to the Pinecone Vector Database Request node as it executes.

14. On the Request tab, set the Data location property to specify the location in the incoming message tree that contains the object data to be created in Pinecone Vector Database. This data forms the request that is sent from the Pinecone Vector Database Request node to the Pinecone Vector Database system.
15. On the Result tab, set the Output data location property to specify the location in the output message tree to contain the data of the record that is created in Pinecone Vector Database.
16. By default, request messages are validated against the request schema that was generated during connector discovery. You can turn off request validation or change the validation settings by using the Validation properties of the Pinecone Vector Database Request node.
17. Save the message flow.
