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.
Hey Community!
We're happy to share a new video from our InterSystems Developers YouTube:
The third developer previews of InterSystems IRIS® data platform, InterSystems IRIS® for Health, and HealthShare® Health Connect 2026.1 have been posted to the WRC developer preview site. Containers can be found on our container registry and are tagged latest-preview.
These developer previews includes the dropping of Mac Intel support starting from 2026.1.0, and the adding back of Windows Server 2019 support to 2026.1.0.
Initial documentation can be found at these links below:
TL;DR This article explains how to deploy InterSystems IRIS Community Edition on Azure using the Azure Marketplace and a Virtual Machine. It covers prerequisites, instance selection, authentication, SSH access, first verification steps, and how to delete resources to avoid charges. The deployment can typically be done using Azure free credits and is suitable for developers who want to quickly start working with IRIS in the cloud.
Who this guide is for. This guide is intended for developers, solution architects, and DevOps engineers who want to deploy InterSystems IRIS Community Edition on Microsoft Azure. No prior Azure automation experience is required, but basic familiarity with the Azure Portal and SSH is helpful.
After following this guide, you will be able to:

This feature works by default with all system Business Hosts. If a user writes their own Business Services, Processes, or Operations, they must implement the OnGetConnections method for this functionality to work with their custom Business Hosts (or use Ens.DataType.ConfigName properties for connections).
That said, the SMP shows only the first layer of connections of the selected Business Host. Sometimes, we need to get connections of connections recursively to build a complete data flow graph. Or we might need this connection information to check which downstream systems might be affected by a change upstream.
PEP 578 added Python Audit hooks. A rich variety of events (module load, os interactions and so on) triggers audit events which you can subscribe to.
Here's how to do that. First create an embedded python hook:
Class User.Python
{
/// do ##class(User.Python).Audit()ClassMethod Audit() [ Language = python ]
{
import sys
import time
def logger(event,args):
if event=='import':
module = args[0]
print(f"Loading {module}")
if module == "numpy":
print(f"Module {module} forbidden. Terminating process in 3.")
time.sleep(3)Who hasn't been developing a beautiful example using a Docker IRIS image and had the image generation process fail in the Dockerfile because the license under which the image was created doesn't contain certain privileges?
In my case, what I was deploying in Docker is a small application that uses the Vector data type. With the Community version, this isn't a problem because it already includes Vector Search and vector storage. However, when I changed the IRIS image to a conventional IRIS (the latest-cd), I found that when I built the image, including the classes it had generated, it returned this error:
In Part 1, we laid the technical foundation of MAIS (Multi-Agent Interoperability Systems). We have successfully wired up the 'Brain', built a robust Adapter using LiteLLM, locked down our API keys with IRIS Credentials, and finally cracked the trick code on the Python interoperability puzzle.
However, right now our system is merely a raw pipe to an LLM. It processes text, but it lacks identity.
Today, in Part 2, we will define the Anatomy of an Agent. We will move from simple API calls to structured Personas.
In my previous HttpRequests, I have used Content-Type = application/json but I have a vendor that is requesting we send application/x-www-form-urlencoded. How would I go about formatting the Payload as x-www-form-urlencoded?

Hi everyone,
Does anyone know how to export projects via VSC?
I opened the project through the "InterSystems Tools" plugin (command is "Edit Code in Project") and I can correctly work on it.
However, when I try using the "ObjectScript" plugin to export the project (right click on the project -> "Export Project Contents")
.png)
This message appears and it is not possible to export the project:

I've tried also to open a new window, then a folder and finally the project, but nothing changes.
This is an example of my workspace:

Anyone knows how to do it?
Thank you!
As applications grow, every database eventually hits scaling limits. Whether it's storage capacity, concurrent users, query throughput, or I/O bandwidth, single-server architectures have inherent constraints. This guide explains fundamental approaches to database scalability and shows how InterSystems IRIS implements these patterns to support enterprise-scale workloads.
We'll explore two complementary scaling strategies: horizontal scaling for user volume (distributing computational load) and sharding for data volume (partitioning datasets). Understanding the general principles behind these approaches will help you make informed decisions about when and how to scale your IRIS applications.
The examples in this guide use InterSystems IRIS in Docker containers.
IPM version 0.10.5 has been released on January 15, 2026. This new version contains a ton of improvements and bug fixes so be sure to check it out either directly from the GitHub page or from the Community Registry!
The big changes include the following:
I wanted to try vibecoding a real backend + frontend setup on InterSystems IRIS, ideally using something realistic rather than a toy example. The goal was simple: take an existing, well-known persistent package in IRIS and quickly build a usable UI and API around it — letting AI handle as much of the boilerplate as possible. Here is the result of the experiments.
I've modified the class file, but messages still arrive as a single line (e.g., "H|.../rQ|.../rL") instead of separate lines in the ASTM service. The <ENQ>..<EOT> header looks correct, logs show no errors, and the service receives messages fine. Is there an Ensemble 2018.1 engine setting (like line terminator handling or TCP framing) to fix the line splitting?
A quick question. What's the shortcut to uncomment multiple lines of code in Studio? And what's the shortcut to comment out multiple lines of code in Studio?
Thanks in advance!
Hello! In this article, I will be discussing database degrade, a type of data integrity issue one can face when using IRIS. First, I will be going over a review of the structure of IRIS databases. I'll then discuss how database degrade can manifest and common causes of degrade issues. I'll then conclude with general tips we give our customers about how to prevent or prepare for database degrade issues.
What exactly is a database?An IRIS database is a single file that consists of a fundamental unit called the "block".
Hello everybody,
I would like to export project contents using Visual Studio Code, as well as I do with InterSystems Studio.
However, while attempting the export through the InterSystems extension I get the following error:
- There are no folders in the current workspace that code can be exported to.

These are the step to reproduce my error:

Anyone can help me solving this issue?

Who this guide is for.
This guide is intended for developers, solution architects, and DevOps engineers who want to deploy InterSystems IRIS Community Edition on Amazon Web Services (AWS). No prior AWS automation experience is required, but basic familiarity with EC2 and SSH is helpful.
What you will achieve.
After completing this guide, you will be able to:

Before you begin, make sure you have:
Deployment overview
The deployment process consists of the following steps:
Hi Gang!
Did you know you can deploy InterSystems IRIS Community Edition on the cloud without paying for a license? You can try for free, and it could even come in handy if you want to show off that shiny new app you've created (maybe for the full stack competition..?)
In this article I will provide a complete walkthrough on how to deploy IRIS on Amazon Web Services (AWS), and will also add a follow up for deploying on Azure.
Now before I begin the walkthrough, I want to admit that I was terrified of using AWS the first time because I'd seen memes about how easy it is to rack up costs on AWS. So if you're thinking the same, I suggest you start by signing up to a Free Tier Account, which gives you $100 free credit to evaluate, and automatically shuts off to prevent charges. InterSystems IRIS Community Edition has a free license so if you pair the two, you can deploy without risk and completely for free. (Disclaimer: although I'm sure this is true, please do read the free account terms and make your own decisions 😅 )
Note, this article walks through deploying IRIS Community on AWS, however the same guide can be followed to deploy IRIS for Health Community Edition, or with Bring-your-own-licence editions of IRIS and IRIS for Health, to deploy a fully licensed, production version of IRIS on AWS.
Here at InterSystems, we often deal with massive datasets of structured data. It’s not uncommon to see customers with tables spanning >100 fields and >1 billion rows, each table totaling hundred of GB of data. Now imagine joining two or three of these tables together, with a schema that wasn’t optimized for this specific use case. Just for fun, let’s say you have 10 years worth of EMR data from 20 different hospitals across your state, and you’ve been tasked with finding….

Can the IRIS SQL engine be extended with custom optimization rules (e.g., prioritizing certain indices or join orders)? If not, is there a supported way to influence cost models?
Hi Community,

How many times have you had to receive or generate a JSON and wished you could work on it using DTLs without having to deal with DynamicObjects trying to remember the name of each field? Do you want to break down and make your giant JSON file more digestible?
In my case, never, but I thought that someone might find it useful to have a feature that captures your JSON and breaks it down into a series of ObjectScript classes that you can work with more easily and conveniently.
Well then...behold JSON2Class in all its glory!

Some concepts make perfect sense on paper, whereas others require you to get your hands dirty. Take driving, for example. You can memorize every component of the engine mechanics, but that does not mean you can actually drive.
You cannot truly grasp it until you are in the driver's seat, physically feeling the friction point of the clutch and the vibration of the road beneath. While some computing concepts are intuitive, Intelligent Agents are different. To understand them, you have to get in the driver's seat.
In my previous articles regarding AI agents, we discussed such tools as CrewAI and La
As mentioned in the previous article, it is possible to configure the way you wish your collections to be stored and queried in SQL.

To set this up, you will need to use the following field parameters and settings:
In InterSystems IRIS, when you compile a persistent class, you automatically get a SQL table. Sometimes, there are situations that require having a slightly (or not so slightly) different names/options in SQL compared to Object model. Here are some of the settings that you can change to make it happen.
They define the "Face" of your class when it appears as a table in the SQL catalog.
SqlTableName allows you to change the name of SQL table that holds objects from your class. This is especially useful, when your class name uses reserved SQL words in a name, e.g. Group.

A question that quickly arises when configuring IAM (aka Kong Gateway) is how many routes should be created to reach all the business objects in an IRIS API.
A common mistake is to create one route per business object, unnecessarily multiplying the number of routes.
Let's take the example of the Supply Chain Orchestrator Data Model API:
/api/SC/scmodel/v1/objects /api/SC/scmodel/v1/objects/BOM /api/SC/scmodel/v1/objects/Carrier /api/SC/scmodel/v1/objects/Customer /api/SC/scmodel/v1/objects/DemandPlan /api/SC/scmodel/v1/objects/InventoryThreshold /api/SC/scmodel/v1/objects/Issue

As mentioned the goal is to give you a smooth “first run” experience.
If you already know Java (or .Net) and perhaps also have used other document databases (or looking for one), but you are new to the InterSystems world, this post should help you.
InterSystems IRIS Cloud Document is a fully managed document database that lets you store JSON documents and query them with familiar SQL syntax, delivered as a cloud service managed by InterSystems.
