How to run a process on an interval or schedule?

When I started my journey with InterSystems IRIS, especially in Interoperability, one of the initial and common questions I had was: how can I run something on an interval or schedule? In this topic, I want to share two simple classes that address this issue. I'm surprised that some similar classes are not located somewhere in EnsLib. Or maybe I didn't search well? Anyway, this topic is not meant to be complex work, just a couple of snippets for beginners.

Interoperability Naming Convention (IRIS Project Organization Guide)

Over time, while I was working with Interoperability on the IRIS Data Platform, I developed rules for organizing a project code into packages and classes. That is what is called a Naming Convention, usually. In this topic, I want to organize and share these rules. I hope it can be helpful for somebody.

What strategy do you use to maintain different settings of Interoperability Productions across DEV, TEST, and PROD environments?

I know the next ones:

1. Place all different settings in environment variables. You have a different .env file for each environment, and you must add some code to Production for reading and setting these values. It's good for deploying into containers, but challenging for management when we have a large production. I mean, we have many settings that can vary depending on the environment: active flag, pool size, timeouts, and so on. Not only endpoints.

Why does InterSystems have no out-of-the-box ESB solution? Let’s try to fix it!

I was really surprised that such a flexible integration platform with a rich toolset specifically for app connections has no out-of-the-box Enterprise Service Bus solution. Like Apache ServiceMix, Mule ESB, SAP PI/PO, etc, what’s the reason? What do you think? Has this pattern lost its relevance completely nowadays? And everybody moved to message brokers, maybe?

"Bad value for type long" on select from PostgreSQL via EnsLib.SQL.OutboundAdapter

Here is my code:

Method getStocks(pRequest As Stock.Message.Req, Output pResponse As Ens.StreamContainer) As %Status
{
     s tSC = pRequest.NewResponse(.pResponse)
     q:$$$ISERR(tSC) tSC

     #dim pRS As EnsLib.SQL.GatewayResultSet

     s tSC = ..Adapter.ExecuteQuery(.pRS, "select jsonb_agg(s) #>> '{}' FROM prod.stocks s where s.""Warehouse"" = ?", pRequest.Warehouse)
     q:$$$ISERR(tSC) tSC

     s pResponse = ##class(Ens.StreamContainer).%New()
     s pResponse.Stream = ##class(%GlobalCharacterStream).%New()
