Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

scylladb-driver-alpha

v0.2.0

Published

Async CQL driver for Node.js, built on top of Rust driver, optimized for ScyllaDB!

Readme

ScyllaDB Node.js-RS Driver

test workflow quality workflow

This is a client-side driver for ScyllaDB written in Node.js and Rust. This driver is an overlay over the ScyllaDB Rust Driver, with the interface based on the DataStax Node.js Driver. Although optimized for ScyllaDB, the driver is also compatible with Apache Cassandra®.

This driver is currently in the experimental state. We are working on features necessary for the driver to be considered production ready.

Getting started

Installation

npm install scylladb-driver-alpha

Currently only linux x86_64 architecture is supported with planned support for other architectures in the future.

Documentation

The API (documentation) of the driver is based on the DataStax driver. Some of the endpoints are already implemented, others are planned, and some parts of the API (including features that were deprecated and are specific to DataStax databases) are removed. The status of each API endpoint is listed in this document and unimplemented features are tracked in the repository issues.

Examples

You can find example usages of the driver in the examples directory.

Features and roadmap

The driver supports the following:

  • Simple, Prepared, and Batch statements
  • Asynchronous IO, parallel execution, request pipelining
  • Token-aware routing
  • Shard-aware and Tablet-aware routing (specific to ScyllaDB)
  • CQL binary protocol version 4
  • Works with any cluster size
  • Both promise and callback-based API
  • Row streaming and pipes
  • Built-in TypeScript support
  • Password authentication

Features that are planned for the driver to become production ready:

  • Configurable load balancing and retry policies
  • Faster performance, compared to DataStax Node.js driver
  • SSL support
  • Error handling, based on the Rust driver
  • Migration guide from the DataStax driver
