Databricks SQL Driver for Node.js

 

Description

The Databricks SQL Driver for Node.js is a Javascript driver for applications that connect to Databricks clusters and SQL warehouses. This project is a fork of Hive Driver which connects via Thrift API.

Requirements

• Node.js 14 or newer

Installation

npm i @databricks/sql

Usage

[examples/usage.js](examples/usage.js)

const { DBSQLClient } = require('@databricks/sql');

const client = new DBSQLClient();

client
.connect({
host: '********.databricks.com',
path: '/sql/2.0/warehouses/****************',
token: 'dapi********************************',
})
.then(async (client) => {
const session = await client.openSession();

const queryOperation = await session.executeStatement('SELECT "Hello, World!"');
const result = await queryOperation.fetchAll();
await queryOperation.close();

console.table(result);

await session.close();
await client.close();
})
.catch((error) => {
console.log(error);
});

Telemetry

The driver emits connection, statement, and CloudFetch metrics plus redacted error events to help Databricks improve driver reliability. No SQL text, parameter values, or row data is ever collected. Emission is gated by a server-side feature flag and can be disabled per-connection with telemetryEnabled: false or globally with the DATABRICKS_TELEMETRY_DISABLED env var.

See [docs/TELEMETRY.md](docs/TELEMETRY.md) for the full event payloads, tuning knobs, multi-tenant guidance, and troubleshooting.

Run Tests

Unit tests

You can run all unit tests, or specify a specific test to run:

npm test
npm test --

e2e tests

Before running end-to-end tests, create a file named tests/e2e/utils/config.local.js and set the Databricks SQL connection info:

{
host: '***.databricks.com',
path: '/sql/2.0/warehouses/***',
token: 'dapi***',
database: ['catalog', 'database'],
}

Then run

npm run e2e
npm run e2e --
