How to stream data from a teradata database in node.js?

@ryleigh 

To stream data from a Teradata database in Node.js, you can use the Teradata Node.js Driver which provides a way to interact with Teradata databases using Node.js.

Here is an example code snippet to stream data from a Teradata database in Node.js using the Teradata Node.js Driver:

const teradata = require('teradata');

const connection = teradata.connect({
  host: 'your-teradata-host',
  user: 'your-teradata-username',
  password: 'your-teradata-password',
  log: 'debug'
});

connection.then(client => {
  const queryStream = client.stream('SELECT * FROM your_table', []);

  queryStream.on('data', data => {
    console.log(data);
  });

  queryStream.on('error', err => {
    console.error(err);
  });

  queryStream.on('end', () => {
    console.log('Finished streaming data');
  });
});

In this example, we first connect to the Teradata database using the teradata.connect method and then use the client.stream method to run a query and stream the data from the result set. We listen for the data, error, and end events on the queryStream object to handle the streaming process.

Make sure to install the Teradata Node.js Driver by running npm install teradata before running the above code.

Remember to replace 'your-teradata-host', 'your-teradata-username', 'your-teradata-password', and 'your_table' with your actual Teradata database details and query.

This is a basic example to get you started with streaming data from a Teradata database in Node.js. Additional configurations and error handling may be required depending on your specific use case.
