temporal VS Faktory

I don't know if I agree with the argument regarding durability vs elastic execution. If I can get both (with a nice API/DX) via something like Temporal (https://github.com/temporalio/temporal), what's the drawback here?

However, as we mentioned, each shard needs management. Part of the management includes a cache of Workflow histories for that shard. We can see the History pods’ memory usage is rising quickly. If the pods run out of memory, Kubernetes will terminate and restart them (OOMKilled). This causes Temporal to rebalance the shards onto the remaining History pod(s), only to then rebalance again once the new History pod comes up. Each time you make a scaling change, be sure to check that all Temporal pods are still within their CPU and memory requests—pods frequently being restarted is very bad for performance! To fix this, we can bump the memory limits for the History containers. Currently, it is hard to estimate the amount of memory a History pod is going to use because the limits are not set per host, or even in MB, but rather as a number of cache entries to store. There is work to improve this: github.com/temporalio/temporal/issues/2941. For now, we’ll set the History memory limit to 8GB and keep an eye on them—we can always raise it later if we find the pod needs more.

Correct, the workflow's guarantee to always complete executing independent of hardware failures is dependent on the database not losing data. You host your workflow code with Temporal's Worker library, which talks to an instance of the Temporal Server [1], which is an open-source set of services (hosted by you or by Temporal Cloud), backed by Cassandra, MySQL, or Postgres. [2] So for instance increasing Cassandra's replication factor increases your resilience to disk failure.

Re:graph frameworks - thanks for the pointers, hadn't heard about them! I'd heard of temporal which I believe provides a similar memoization capability with the purpose of not losing work in workflows that failed partway through?

Documentation

Personally I am leveraging the knowledge and momentum of Replay to dive into the Python SDK, build out a couple of applications to deepen my knowledge around Workflows, Activities, and metrics, and continue inhaling knowledge via the monthly meetup, the application development guide, and documentation. By next year I’ll experience the conference, not as one new to Temporal, but as an expert—maybe even as one of the people helping with the architecture review or running a Birds of a Feather; if anything, I know I look forward to seeing YOU at next year’s event!

Mike Perham (the sidekiq maintainer) also maintains the less well known faktory[0] which is language agnostic and has runners for both Ruby and Python

Zen and the Art of Motorcycle Maintenance's entire thesis is "What is Quality?" How do you define it? How does it come about?

You can still get software quality but you have to be willing to devote time and effort to it. The binary for my modern, commercial background job engine written in Go, Faktory, is 5MB in size.

https://github.com/contribsys/faktory/releases/tag/v1.8.0

I know when I see an iOS app that is 5-10MB in size, I know it was crafted by someone who cares.

My recent queue foray put me on the scent of Faktory, a language-agnostic queue server made by Sidekiq's author. I noticed there wasn't a good PHP client (the one linked in the docs is pretty old), so I decided to build one.

At work we use https://github.com/contribsys/faktory

Have you heard of faktory before? Made by the sidekiq guy and allows you to d a similar thing.

I’ve started using Faktory with the Faktory Worker Python it also supports workers in any language.

Try https://github.com/contribsys/faktory which is written in go but you interact with it as a service.

There is faktory, from the author of Sidekiq, which is language-agnostic (the server is written in Go).
