InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.
Hi Community,

The 2026.1 release of InterSystems IRIS® data platform, InterSystems IRIS® for Health, and InterSystems Health Connect™ is now Generally Available (GA). This is an Extended Maintenance (EM) release.
Hi Community,
Take a look at these new videos in online learning, and get familiar with new features and interfaces in the latest release of InterSystems® products. All videos are also available in the Learning Services YouTube channel.
Plus, check out a video for new ObjectScript developers, and a guide for HealthShare® users upgrading their deployments.
We were testing upgrades on our internal systems recently, and were initially surprised to see a change in some instances of SQL behavior. On further investigation, the changes make a lot of sense, and are easy to adapt to. But, to hopefully save you some time and provide additional information in case this is something you too find curious or interesting, we thought we would share our understanding of the changes and how we got around it to preserve previous behavior where desired.
Starting in IRIS version 2024.2.
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.
Hi, Community!
Are you working with large tables? See how partitioning helps you manage and query your data:
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.
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.
Since our previous announcement, we have introduced several incremental improvements to the client‑side editing experience in VS Code. These updates focus on preserving developer‑authored formatting when synchronizing with the server.
Client‑side *.cls files previously lost certain formatting details during compilation, including keyword casing (e.g., classmethod → ClassMethod), normalization of blank lines between class members, and removal of line breaks within parameter lists.
The George James Software team is looking forward to going to National Harbor for READY 2026!
As part of the conference, we'll be hosting our Deltanji Source Control User Group:
Date: Wednesday, April 29th
Time: 8 - 9am (breakfast will be provided)
Location: Azalea 1
RSVP by emailing laurelj@georgejames.com.
We'll be showing what will be included in the next release of Deltanji, version 8.2, as well as providing an opportunity for questions and discussion. We welcome both current and prospective users to join us.
The Management Portal doesn't have a native way to switch to Dark Mode. This can be resolved using a Chrome extension called Dark Reader. See the result:
To install and use the Dark Reader:
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.
This article reflects my recent experiences at trying to connect an IRIS Business Operation to a secure Kafka Server, using SSL tunnels to encrypt the communications and using SASL (Simple Authentication and Security Layer) password hashing with SCRAM-SHA-512.
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:
As mentioned the goal is to give you a smooth “first run” experience.
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:
Next, my ideas (none of them look like a silver bullet):
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.

During my work with customers and also following I often met the
explicit or embedded question: What is this "GLOBALS" ?
I'll try to explain the history to unfold the context.
Has anyone done this successfully? Customer wants to receive HL7 data over https using OAUTH 2.0 client credentials. I am assuming a custom Operation will be needed? I tried using CoPilot for assistance but was unsuccessful. I am not great with Object script :(
Hey Developers,

I'm a huge sci-fi fan, but while I'm fully onboard the Star Wars train (apologies to my fellow Trekkies!), but I've always appreciated the classic episodes of Star Trek from my childhood. The diverse crew of the USS Enterprise, each masterminding their unique roles, is a perfect metaphor for understanding AI agents and their power in projects like Facilis. So, let's embark on an intergalactic mission, leveraging AI as our ship's crew and boldly go where no man has gone before
Customer support questions span structured data (orders, products 🗃️), unstructured knowledge (docs/FAQs 📚), and live systems (shipping updates 🚚). In this post we’ll ship a compact AI agent that handles all three—using:

There is data, such as execution log data, that you do not want to return to its previous state even if a rollback occurs during a transaction. The above requirement can be met by placing that data in the IRISTEMP database, which will not be rolled back.
Temporary Globals and the IRISTEMP Database
By mapping the table entities you do not want to roll back to this database, you can retain the information after the rollback.
