Senior engineering is defined not by the volume of code produced, but by the strategic avoidance of it. In complex integration environments, the tendency to utilize general-purpose libraries for every niche requirement introduces unnecessary overhead. True architectural maturity requires a commitment to "minimalist tooling"—prioritizing resilient, battle-tested system utilities over custom logic. This assessment examines our PGP encryption/decryption pipeline to demonstrate how shifting from application-level libraries to OS-native delegation enhances system durability.

Question Scott Roth · 5 hr ago

Was wondering if anyone had a Dynamic way to see if a Global is still being used by a Class File. 

We have been monitoring our Global Size recently, and I am trying to find problematic Class files that are not being cleaned up or used appropriately. I have come across some globals that do not seem to have a Class attached to them anymore, and instead of deleting globals 1 by 1, I was looking for a way that we could dynamically do this since the globals have data that is stale in them.

Thanks

Scott

Hey Community, 

Yeah, I know we have a lot of tips & tricks articles - we even have a special tag for it, right? But I can not share my own collection. In this collection, you can find snippets for beginners, as well as some everyday ObjectScript constructions. In fact, it's also a way to learn something new about my favorite programming language. So, if you guys have anything to add, you are welcome!

Today I have published a new Open Exchange package for generation of Synthetic Data directly into IRIS.

 It can be a frustrating process to find decent datasets when you are looking to make a demo app. Maybe the dataset doesn't matter that much, but you still want it to appear somewhat genuine and with several linked tables that are usable directly within IRIS with the neat implicit joins with ->. Maybe you just want linked tables that are easily installable with IPM to benchmark queries, this dataset generation would be perfect.

Table Partitioning Demo

This demo walks you through the new Table Partitioning feature in IRIS SQL, explaining what it does and how it works along the way. We'll only use a few dozen rows to prove the concept, but obviously the capability is focused on datasets many orders of magnitude larger.

If you'd like a shorter, higher-level introduction to Table Partitioning, check out the online learning module Managing Tables with Partitioning in InterSystems IRIS

 

ℹ️ Table Partitioning is included in IRIS 2026.1 as an experimental feature

In last post I talked about iris-copilot, an apparent vision that in near future any human language is a programming language for any machines, systems or products. Its agent runners were actually using such so-called 3rd generation of agents. I want to keep/share a detailed note on what it is, for my own convenience as well. It was mentioned a lot times in recent conversations that I was in, so probably worth a note.

>> Answer the question below to be entered in the raffle!


⏯️ AI-Assisted Rare and Complex Disease Detection

This demo shows how InterSystems Health Gateway can be used to pull in outside patient records from networks like Carequality, CommonWell, and eHealth Exchange, creating a more complete longitudinal view in a clinical viewer. That full record is then analyzed by AI to surface potential rare disease considerations with clear reasoning, helping clinicians see patterns they might otherwise miss.

Question Mark Charlton · Apr 13

I'm starting to play more with AI enabled coding. 
I've been using Github Copilot inside Visual studio code, which is very good at coming up with autocomplete suggestions that are accurate and useful. (Along with some utter rubbish, naturally).
For web development I'm starting to use Claude Code in VS Code to help create web sites and integrations. I want to see how it can help with IRIS development. 

However I can't get claude to read any iris code directly as I'm connected to my server via isfs server connections.

Most IRIS developers use $LISTBUILD every day — often without even noticing it.

It is not just a convenient function for building lists. It is also the default internal format used to store row data, global values, and many intermediate structures inside the database engine.

Despite this, the actual binary representation of $LISTBUILD values is rarely discussed. Most developers rely on its behavior, but never look at how the data is really stored.

This article focuses strictly on the binary layout of $LISTBUILD values, based on direct inspection via zzdump.

This is the second part of an article pair where I walk you through:

  • Part I - Intro and Quick Tour (the previous article)
    • What is it?
    • Spinning up an InterSystems IRIS Cloud Document deployment
    • Taking a quick tour of the service via the service UI
  • Part II - Sample (Dockerized) Java App (this article)
    • Grabbing the connection details and TLS certificate
    • Reviewing a simple Java sample that creates a collection, inserts documents, and queries them
    • Setting up and running the Java (Dockerized) end‑to‑end sample

As mentioned the goal is to give you a smooth “first run” experience.

Question Andrew Sklyarov · Apr 18

I need a %SYS.Python object that will be accessible from different processes. The goal is to avoid reinitializing the Python object whenever it is called. Ways that I checked and decided that it is NOT what I want:

  • %-variables (process variables). Reusing only in the same process
  • Save-and-restore via globals. Restoring means heavy initialization, which I want to avoid

Next, my ideas (none of them look like a silver bullet):

  • Using Interoperability Production.

Hello, community.

I've been working with Intersystem Caché for two years, and right away I was excited about the rich ecosystem that Caché provides. However, I was disappointed with calls using #call, and I understand that it was a limitation of the time. Well, the frustration is that #call returns null by default, meaning an AJAX request is executed, but there's no hook to retrieve the return from that request. The only way to retrieve the data from that request is by building a callback on the server side using &js<>.

What is a Microservice?

A microservice is an architectural style that structures an application as a collection of small, autonomous services. Each component is developed around a specific business capability, can be deployed independently, and is typically managed by a miniature, specialized, self-governing team.
