FunctionGraph

The FunctionGraph connector is used to interconnect with FunctionGraph to call created functions to process data. The processing result can be referenced in subsequent nodes by referencing variables.

Prerequisites

To use FunctionGraph, you need to have the FunctionGraph Administrator permission for project-level services.

Creating a FunctionGraph Connection

  1. Log in to the new ROMA Connect console.
  2. In the navigation pane on the left, choose Connector. On the page displayed, click New Connection.
  3. Select the FunctionGraph connector.
  4. In the dialog box displayed, configure the connector and click OK.

    Parameter

    Description

    Name

    Authenticated By

    Select an authentication mode for the connector.

    Access Key

    Mandatory when Authentication Mode is set to AK/SK.

    Access key ID (AK) of the current account. Obtain the AK by referring to Access Keys. If an AK/SK pair has been generated, find the downloaded AK/SK file (such as credentials.csv).

    Secret Access Key

    Mandatory when Authentication Mode is set to AK/SK.

    Secret access key (SK) of the current account. Obtain the SK by referring to Access Keys. If an AK/SK pair has been generated, find the downloaded AK/SK file (such as credentials.csv).

Action

Invoking a function

Configuration Parameters

Parameter

Description

Region

Region where FunctionGraph is located.

Project

Project to which FunctionGraph belongs.

Function

Select the function to be invoked.

Calling Method

Select an invocation mode for the function. Currently, only Synchronous is supported.

Request Data

The request body for executing a function must be in JSON format. You can use data from previous nodes by referencing variables.

FunctionGraph provides powerful data processing capabilities in various scenarios. For example, when you use a Data Source component to query BLOB data (such as images) from a database (such as MySQL), the query result is in byte arrays. In this case, the queried data can be further processed with FunctionGraph, for example, Base64 data encoding.
