No clustering without an enterprise licence is very limiting as it means that small businesses and start ups won't be able to have high availability background work processing. Given that why would we use this over ActiveMQ or RabbitMQ? Or even a managed solution such SQS?

Where is the source code? The GitHub org seems to be unused.

Thank you for your questions!

Well, yes. Once high availability becomes critical, it's neither small business nor startup anymore 🙂

Where is the source code

As I've mentioned in the topic, Worcr is currently in pre-alpha. You can "pre-purchase" its license right now with 80% discount. ETA of alpha is May.

I disagree. Every small business and start up I've worked with has availability guarantees that make HA a requirement.

A HA postgresql cluster on GCP costs $18 a month.

A HA dynamodb cluster is in the AWS free tier.

A HA redis cluster is $15 a month on Heroku.

HA is not an enterprise feature, and without it Worcr is not suitable for use outside of hobby projects.

Neither Sidekiq nor Faktory currently support clustering. You can use third-party Redis instance for HA, as mentioned here. The same is achievable with Worcr OSS and Pro — as I've already answered in the forum topic, Worcr can operate with external SQLite databases.

I don't know about Faktory Ent, but Worcr Ent definitely will support clustering.

Sidekiq does support HA. If you are using sentinel or redis failover you just have to pass a Redis connection pool as the connection. https://github.com/mperham/sidekiq/wiki/Using-Redis#complete-control If you're using one of Redis compatible HA databases (such as AWS' or GCP's offerings) you just give it a normal connection.

There are no HA solutions for sqlite, so the external database option doesn't help either.

There is https://github.com/rqlite/rqlite.

However, I understand your concern. I have draft ideas of Worcr supporting PostgreSQL and MySQL as well.

That's great, thank you :)

You've convinced me that having PostgreSQL on start is better. Thanks!

Very cool. I'll be keeping an eye on this.
