Query Phoenix Data as a SQL Server Database in Node.js
You can use CData Connect AI to query Phoenix data through a SQL Server interface. Follow the procedure below to create a virtual database for Phoenix in Connect AI and start querying using Node.js.
CData Connect AI provides a pure MySQL, cloud-to-cloud interface for Phoenix, allowing you to easily query live Phoenix data in Node.js — without replicating the data to a natively supported database. As you query data in Node.js, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc) directly to Phoenix, leveraging server-side processing to quickly return Phoenix data.
Configure Phoenix Connectivity for NodeJS
Connectivity to Phoenix from NodeJS is made possible through CData Connect AI. To work with Phoenix data from NodeJS, we start by creating and configuring a Phoenix connection.
- Log into Connect AI, click Sources, and then click Add Connection
- Select "Phoenix" from the Add Connection panel
-
Enter the necessary authentication properties to connect to Phoenix.
Connect to Apache Phoenix via the Phoenix Query Server. Set the Server and Port (if different from the default port) properties to connect to Apache Phoenix. The Server property will typically be the host name or IP address of the server hosting Apache Phoenix.
Authenticating to Apache Phoenix
By default, no authentication will be used (plain). If authentication is configured for your server, set AuthScheme to NEGOTIATE and set the User and Password properties (if necessary) to authenticate through Kerberos.
- Click Save & Test
-
Navigate to the Permissions tab in the Add Phoenix Connection page and update the User-based permissions.
Add a Personal Access Token
When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.
- Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
- On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
With the connection configured and a PAT generated, you are ready to connect to Phoenix data from Node.js.
Query Phoenix from Node.js
The following example shows how to define a connection and execute queries to Phoenix with the SQL Server module. You will need the following information:
- server: tds.cdata.com
- port: 14333
- user: a Connect AI user (e.g. [email protected])
- password: the PAT for the above user
- database: The connection you configured for Phoenix (ApachePhoenix1)
Connect to Phoenix data and start executing queries with the code below:
var sql = require('mssql')
var config = {
server: 'tds.cdata.com',
port: 14333,
user: '[email protected]', //update me
password: 'CONNECT_USER_PAT', //update me
options: {
encrypt: true,
database: 'ApachePhoenix1'
}
}
sql.connect(config, err => {
if(err){
throw err ;
}
new sql.Request().query('SELECT * FROM MyTable', (err, result) => {
console.dir(result)
})
});
sql.on('error', err => {
console.log("SQL Error: " ,err);
})
