Scheduling and Recurring Jobs with MassTransit

[@michaelgraf4612]

Not mentioned in this video, but I see Job Distribution Strategies were delivered in 8.3.0. This is huge for folks building multi-tenant apps that unfortunately have to route jobs for some clients to specific machines. I'm really excited to try it. Thanks!

I pulled job distribution from the concepts column after this video was published, but yes, that's coming as well and already in the documentation.

​@@PhatBoyGfor some reason I thought 8.3.0 had already been released. My mistake. Looking forward to it then!

[@PhatBoyG]

@@michaelgraf4612 Only the pre-release builds are available now, under the 8.2.6-develop lineage.

Very nice stuff! 🙂 When is this going to land on main branch? 🙂

[@PhatBoyG]

The next release will have it, either 8.2.6 or I might bump to 8.3.0 since it's a schema change on the job service sagas.

Cool stuff! This is probably capable of scheduling messages in single digit second frequencies, I assume? I'm currently running a selfmade redis round robin lock-based scheduler, but I would like to replace that one. I didn't use Quartz yet, but Hangfire did fail miserably at frequencies of

[@PhatBoyG]

I mean, technically it should be capable of that, but this is not meant to be a generalized scheduling solution. I have other videos giving more details on what job consumers are and how they should be used that might be worth watching.

Can recurring jobs be used with Azure servicebus or only with Postgres?

[@PhatBoyG]

Any transport can be used, for Azure Service bus, you'd just change the SQL scheduler to the UseServiceMessageMessageScheduler.

Amazing library but so complicated to use it.

[@PhatBoyG]

Building distributed systems is hard. MassTransit makes it easier, but the complexity cannot be avoided without serious downstream consequences. This isn't beginner-level material, it's for people building durable, reliable applications that operate at scale. That stated, there are over one hundred videos and more than a dozen samples showing how to use MassTransit, not including content created by others.

Please lower your noise cancelling on your recording. It was hard to listen to.

I'm not sure what happened, the audio is normally fine but this video's audio is really off. Some of the tools I use were updated, I wonder if they somehow changed a setting.
