@lakehouse-rs/flight-sql-client v0.0.10

@lakehouse-rs/flight-sql-client

A client library for interacting with Arrow Flight SQL enabled databases from Node.js.

This library provides a thin wrapper around the flight-sql client implementation in the arrow-flight crate. Node bindings are created with the help of napi-rs.

Usage

Install library

yarn add @lakehouse-rs/flight-sql-client
# or
npm install @lakehouse-rs/flight-sql-client
# or
pnpm add @lakehouse-rs/flight-sql-client

Create a new client instance

import { ClientOptions, createFlightSqlClient } from '@lakehouse-rs/flight-sql-client';
import { tableFromIPC } from 'apache-arrow';

const options: ClientOptions = {
  username: 'flight_username',
  password: 'testing123',
  tls: false,
  host: '127.0.0.1',
  port: 50051,
  headers: [],
};

const client = await createFlightSqlClient(options);

Execute a query against the service

const buffer = await client.query('SELECT * FROM my_tyble');
const table = tableFromIPC(buffer);

Or inspect some server metadata

const buffer = await client.getTables({ includeSchema: true });
const table = tableFromIPC(buffer);

Release

Releases are automated via github actions.

To create a release, first increment the version. (note the use of npm)

npm version <patch | minor | major | ...>

this will bump all version fields, and create a new commit with the version number.

Then trigger the release.

git push --follow-tags
