CData Connect Server


Use CData Connect Server to connect to Cassandra from Nintex Workflow Cloud and build custom workflows using live Cassandra data.

Nintex Workflow Cloud is a cloud-based platform where you can design workflows to automate simple or complex processes using drag-and-drop interactions — without writing any code. When paired with CData Connect Server, you get instant, cloud-to-cloud access to Cassandra data for business applications. This article shows how to create a virtual database for Cassandra in Connect Server and build a simple workflow from Cassandra data in Nintex.

CData Connect Server provides a pure MySQL, cloud-to-cloud interface for Cassandra, allowing you to build workflows from live Cassandra data in Nintex Workflow Cloud — without replicating the data to a natively supported database. Nintex allows you to access data directly using SQL queries. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc.) directly to Cassandra, leveraging server-side processing to quickly return the requested Cassandra data.

Create a Virtual MySQL Database for Cassandra Data

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Log into Connect Server and click Databases.
  2. Select "Cassandra" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Cassandra.

    Set the Server, Port, and Database connection properties to connect to Cassandra. Additionally, to use internal authentication set the User and Password connection properties.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Cassandra data from Nintex.

Connect to Cassandra in Nintex

The steps below outline creating a new connection for access to Cassandra CData Connect Server from Nintex to create a new Cassandra data source.

  1. Log into Nintex Workflow Cloud
  2. In the Connections tab, click "Add new"
  3. Select MySQL as the connector and click "Connect"
  4. In the MySQL connection wizard, set the following properties:
    • Connection Name: name the connection (e.g., CData Connect Server Cassandra Connection)
    • Username: your Connect Server username
    • Password: your Connect Server password
    • Database Host: your Connect Server MySQL endpoint (e.g., myinstance.cdatacloud.net)
    • Database Name: the virtual Cassandra database (e.g., Cassandra1)
  5. Click "Connect"
  6. Configure the connection permissions and click "Save permissions"

Create a Simple Cassandra Workflow

With the connection to CData Connect Server configured, we are ready to build a simple workflow to access Cassandra data. Start by clicking the "Create workflow" button.

Configure the Start Event Action

  1. Click the start event task and select the "Form" event
  2. Click "Design form"
  3. Drag a "Text - Long" element onto the Form and click the element to configure it
    • Set "Title" to "Enter SQL query"
    • Set "Required" to true
  4. Drag a "Text - Short" element onto the Form and click the element to configure it
    • Set "Title" to "Enter desired result column"
    • Set "Required" to true

Configure an "Execute a Query" Action

  1. Add an "Execute a query" action after the "Start event: Form" action and click to configure the action
  2. Set "SQL Script" to the "Enter SQL Query" variable from the "Start event" action
  3. Set "Column to retrieve" to the "Enter desired result column" variable from the "Start event" action
  4. Set "Retrieved column" to a new variable (e.g., "values")

Configure a "Send an Email" Action

  1. Add a "Send an email" action after the "Execute a query" action and click to configure the action
  2. Set the "Recipient email address"
  3. Set the "Subject"
  4. Set the "Message body" to the variable created for the retrieved column

Once you configure the actions, click "Save," name the Workflow, and click "Save" again. You now have a simple workflow that will query Cassandra using SQL and send an email with the results.
