You've probably encountered the terms Data Lake, Data Warehouse, and Data Fabric everywhere over the last 10-15 years. Everything can be solved with one of these three things, or a combination of them ( here and here are a couple of articles from our official website in case you have any doubts about what each of these terms means). If we had to summarize the purpose of all these terms visually, we could say that they all try to solve situations like this:

Our organizations are like that room, a multitude of drawers filled with data everywhere, in which we are unable to find anything we nee

In IRIS, every time a request need to be processed, a specific IRIS process (IRISDB.EXE) need to be assigned to handle that request.

If there is no spare IRIS process at that time, process will need to be created (and later destroyed). On some Windows systems (especially with security/antimalware solutions being active) creating new processes can be slow, which can results in delays during peak times (due to inrush of requests).

Because of that, it's sometimes useful to have some a certain number of processes already created and idling, for handling requests, especially during peak times (eg

1. I like the Application Error Log functionality a lot. However, it becomes time consuming to inspect it date by date and directory by directory on a multidirectory server. Ideally, I would use an existing error class to write a custom error report by date, selected namespaces, etc. Does such a system class actually exist? Not that I found. The detail level on the screenshot below is enough.  
2. Some Application Error Logs go back a couple of years and load for a long while. Is there any programmatic way to clean them? Deleting errors in GUI date by date and directory by directory is rather ted

Hi Community

I'm working on a complex piece of rules that needs to check each OBX and evaluate if 3 of the fields match certain criteria. I've tried to achieve this using a Foreach loop, which does work, however it is not as clean as I wanted it. I was hoping I could assign temp variables inside the foreach loop to make the rules more easier to read, for example @testCode @resultText. This is not support as you can only assign inside a when condition. Before I raise this as an idea, i wondered if there was an alternative way to achieve the same thing?

I seem to remember making this work before, but I'm not having any luck digging up examples.

I've defined some custom properties for a business operation that could definitely benefit from having popup descriptions available in the Production Configuration. I have triple-slash comments before each property that do just that in the source. I thought those provided the text for the popup descriptions when clicking on the property name, but apparently not.

Any thoughts?

is there a way to include a pdf in a zen report in  a stream field?

I am looking to create a Python virtual environment (venv) so that my imported/installed python packages can be separate on different namespaces in IRIS. I am able to go and create an environment, activate it, and install packages, but I am not sure how to ensure that Embedded Python methods actually point to this virtual environment. 

Is the best solution to just load the virtual environment at runtime, in each method? That seems like a bad solution. Has anyone run into this and found a good solution?

Is there a programmatic method or specific property to differentiate system-defined (/csp/altelier , /api/mgmnt and so on)  or user-defined web applications in IRIS?

Thanks!

Hey Community!

We're excited to introduce a new way to interact with the Developer Community AI — you can now have a real conversation with it!

Instead of just asking one-off questions, you can chat with DC AI in a more natural, back-and-forth format. This way, whether you're exploring InterSystems technologies, debugging code, or learning something new, DC AI is here to help, just like a fellow developer.

Hi everyone,

I'm working with JavaScript in InterSystems IRIS, specifically in CSP pages. One issue I'm running into during development is that the browser keeps loading the cached version of my JavaScript files, even after I’ve made changes or recompiled the code.
I would have to clear my cache files or browser history for it to reload and work.

Is there a recommended way or best practice in IRIS to automatically clear or bypass the browser cache for JavaScript? Ideally, I’m looking for a way to ensure that the latest version of the script is always loaded without manually clearing the cache

Hi fellow developers!

Curious if you guys use CreatedAt and LastUpdated properties in your classes?

Created to stamp when the record was created and LastUpdated when it was last updated. Where it can be useful - almost everywhere )) I find it convenient in records sorting (e.g. by creation or last update), in sync (with other systems), and so on, for better analytics.

Do you use it all the time for all the classes?

If don't, why not? What do you use instead?

What property type do you use - %TimeStamp? %DateTime?

What is the best practice to have CreatedAt filled automatically during creation and LastUpdated on every successful save (guess it could be in %OnSave)?

Please share your experience /thoughts?
