05/19/2022, 10:50 PMHi, beginner question ... As there's a limit of 5 targets with Event Bridge, is it more preferable to use SNS -> SQS -> Lambda, rather than EB -> SQS -> Lambda ?
I'm thinking the 5 target limit could be an issue as the application grows.

05/19/2022, 10:50 PMit's 5 targets per rule, in general you should really only have 1 target per rule

thdxr
05/19/2022, 10:51 PMshould create a rule per consumer
thdxr
05/19/2022, 10:51 PMthere's a 300 rule soft limit which as you approach you can request more

Rudi

05/19/2022, 11:21 PMAs a new user, I'm not sure if EB limits will be a factor, but I did see a youtube clip saying they'd only use EB for external integrations and use SNS+SQS for the internal parts of the app.
Rudi
05/19/2022, 11:22 PMI've done the basic POC with EB, so I might just roll with that.
If ever it's an issue, SST makes refactoring easy right 🙂

05/19/2022, 11:22 PMThe main nice thing is just having one place to throw everything, and subscribe everything. With SNS you need many places. It isn’t hard or anything, but it does take more deployments, usually.
Derek Kershner
05/19/2022, 11:23 PMFWIW, we were going to blow through the 300 rule limit in magnitudes, so we went SNS, backing your youtube video.
Derek Kershner
05/19/2022, 11:24 PMWe were all internal, at least for the use case being looked at.

05/19/2022, 11:25 PMHmm, that's interesting. More than 300 rules..

Derek Kershner
05/19/2022, 11:25 PMYeah, you need a rule for basically every subscription, as Dax said above.
Derek Kershner
05/19/2022, 11:26 PMWe are thousands to tens of thousands, most likely.

Rudi
05/19/2022, 11:28 PMI'm tinkering on search and report app, all internal with HTML the end output.
Think I'll be well under 300 for this app.

Derek Kershner
05/19/2022, 11:29 PMthen any will work
Derek Kershner
05/19/2022, 11:34 PMoh, one thing to keep in mind Rudi, is that
Cronr
Rudi
05/19/2022, 11:35 PMYep, always go non-default - thx!
Cron is also a core feature of the app, not so much API based.
