Blitz VS Sidekiq

Blitz is also an open-source project that allows users to access the code and allows to contribute. Their community has generated a lot of impact as well, and has grown rapidly over time since the creation in 2020:

Not yet, I actually just whipped it up quickly last week after I was browsing the Notion subreddit and it reminded me of myspace.

These are the tools I used:

* BlitzJS (https://github.com/blitz-js/blitz)

Hello, I'm the creator of Blitz.js (first announced 2.5 years ago)

Today the Blitz.js 2.0 pivot to a modular Next.js toolkit reached Beta status [1]

Previously Blitz abstracted Next.js, but Blitz 2.0 is now a modular toolkit that plugs into any new or existing Next.js app. Blitz picks up where Next.js leaves off, providing libraries and conventions for shipping and scaling small to large apps.

When I first created Blitz, my aim was to have an all-in-one fullstack framework for Javascript like Ruby on Rails. But that proved to be too difficult. I've decided that achieving an all-in-one framework for JS like Rails is too difficult unless you have a ton of funding and don't have to make meaningful money.

The difference with JS is that client-side frameworks like React have an incredible amount of complexity. Trying to manage all of that and all the other fullstack framework stuff like API layers, auth, file uploads, etc is too large of scope.

So now Blitz is no longer trying to do it all and is focusing on all the non-frontend functionality you need to ship web apps.

Going forward, we want to be the most trusted technical resource for rapidly building and scaling full-stack TypeScript apps.

There's something wrong at Redislabs, it took them over a year to get RESP3 rolled out into their hosted service, you'd expect a rollout of that to be a bit quicker when they're the owner of Redis.

It affected us when upgrading Sidekiq to version 7, which dropped support for older Redis, and their Envoy proxy setup didn't support HELLO and RESP3: https://github.com/sidekiq/sidekiq/issues/5594

That depends on how the `maxmemory-policy` is configured, and queue systems based on Redis will tell you not to allow eviction. https://github.com/sidekiq/sidekiq/wiki/Using-Redis#memory (it even logs a warnings if it detects your Redis is misconfigured IIRC).

Sidekiq https://sidekiq.org/: This one started as an open source project, once it got enough traction, the developer made a premium version of it, and makes money by selling licenses to businesses.

Sidekiq will drop in-progress jobs when a worker crashes. Sidekiq Pro can recover those jobs but with a large delay. Sidekiq is excellent overall but it’s not suitable for processing critical jobs with a low latency guarantee.

> I'm not sure feature withholding has traditionally worked out well in the developer space.

I think it's worked out well for Sidekiq (https://sidekiq.org). I really like their model of layering valuable features between the OSS / Pro / Enterprise licenses.

I was studying Sidekiq's page on rate limiters. The first type of rate limiting mentioned is the concurrent limiter: only n tasks are allowed to run at any point in time. Note that this is independent of time units (e.g. per second), or how long they take to run. The only limitation is the number of concurrent tasks/requests.

The code above isn't idempotent. If you run it twice, it will create two copies, which is probably not what you intended. Why is this important? Because most backend job processors like Sidekiq don't make any guarantees that your jobs will run exactly once.
