Introduction

The InterSystems IRIS Data Platform has long been known for its performance, interoperability, and flexibility across programming languages. For years, developers could use IRIS with Python, Java, JavaScript, and .NET — but Go (or Golang) developers were left waiting.

That wait is finally over.

The new go-irisnative driver brings GoLang support to InterSystems IRIS, implementing the standard database/sql API. This means Go developers can now use familiar database tooling, connection pooling, and query interfaces to build applications powered by IRIS.

Why GoLang Support Matters

GoLang is a language designed for simplicity, concurrency, and performance — ideal for cloud-native and microservices-based architectures. It powers some of the world’s most scalable systems, including Kubernetes, Docker, and Terraform.

Bringing IRIS into the Go ecosystem enables:

• Lightweight, high-performance services using IRIS as the backend.
• Native concurrency for parallel query execution or background processing.
• Seamless integration with containerized and distributed systems.
• Idiomatic database access through Go’s database/sql interface.

This integration makes IRIS a perfect fit for modern, cloud-ready Go applications.

Following 2 local Webinars we had focused on VS Code ["Intro" and "Beyond Basics"; in Hebrew], I prepared for the participants some related links of relevant resources which we sent as a follow-up. Sharing them here as well for the benefit of the Community.
You are all of course welcome to add more useful resources.

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.

Window functions in InterSystems IRIS let you perform powerful analytics — like running totals, rankings, and moving averages — directly in SQL.
They operate over a "window" of rows related to the current row, without collapsing results like GROUP BY.
This means you can write cleaner, faster, and more maintainable queries — no loops, no joins, no temp tables.

In this article let's understand the mechanics of window functions by addressing some common data analisys tasks.

Introduction to SQL Window Functions in InterSystems IRIS

SQL window functions are a powerful tool for data analysis.

Hi Guys,

I'm a newbie in term of MQTT clients & brokers, and I've created a MQTT adapter to connect to a broker and I asked our system admin for the user/pass and the URL and this where we got stuck.

The admin is saying that all he has is IP address to the PEM key to the server itself, so my question is, is the broker the server itself and the url is the url to the server or is the Broker an application (eg. Mosquito) that runs in a server and if that's the case and if its Mosquito,  where do I find the connection details to it (user/pass & URL) ?
Thanks

Thanks

InterSystems FAQ rubric

When exporting using the Export() method of the %Library.Global class, if the export format (fourth argument: OutputFormat) is set to 7, "Block format/Caché block format (%GOF)," mapped globals cannot be exported (only globals in the default global database of the namespace are exported). To export mapped globals in "Block format/Caché block format (%GOF)," specify the database directory to which you want to map them in the first parameter of %Library.Global.Export().

An example of execution is shown below.

What is XML?

XML (eXtensible Markup Language) is a flexible, text-based, and platform-independent format used to store and transport data in a well-structured way that is both human- and machine-readable. XML permits users to define custom tags to describe the meaning and organization of their data. For example: <book><title>The Hitchhiker's Guide</title></book>.

An XML document is self-descriptive and structured as a hierarchical tree of elements. Every document has a single root element that encapsulates all other content.

There is documentation for single dolalr macros but $$$ dollar seems to be referenced on individual pages or not at all.

InterSystems IRIS Adaptive Analytics version 2025.4.1 is now available from the InterSystems Software Distribution page.  This release includes AtScale 2025.4.1 and is compatible with the existing  Adaptive Analytics User-Defined Aggregate Function (UDAF) file - 2024.1.  New features included in AtSCale's 2025 releases include:

• Several MDX improvements to better handle null values and semi-additive measures like year-to-date.
• New parameters to enable setting the visibility of calculations and calculation groups in BI tools.

ObjectScript doesn't include any built-in method for appending one JSON dynamic array to another. Here's a code snippet I use that's equivalent to the JavaScript concat() method.

Call it with any number of arguments to concatenate them into a new array. If an argument is a dynamic array, its elements will be added. Otherwise the argument itself will be added.

ClassMethod ConcatArrays(pArgs.) As %DynamicArray
{
	set outArray = ##class(%DynamicArray).%New()
	for i=1:1:pArgs {
		set arg = pArgs(i)
		if ($IsObject(arg) && arg.%IsA("%DynamicArray")) {
			set iter = arg.

CCR users can now take advantage of an enhanced syntax for substituting pre-defined tokens with live URL links within phase-related text fields. In addition to the existing <env> token which automatically updates to reflect the Environment of the relevant CCR Record, CCR now introduces three new keywords: <smp> , <smpPrefix> , and <homepage>.

The new <smp> token automatically replaces itself with the URL of the Management Portal's homepage for the System associated with the CCR Record in the Environment that most recently received changes to the Record.

For one of our customers I had to integrate with the AFAS imageconnector endpoint /imageconnector/{imageId}?format={format}. This endpoint returns in a json message with the image as a base64-encoded string property, in addition to the mimetype for the image:

/// Image Object
Class Mycustomer.Model.AfasGet.Image Extends (%SerialObject, %XML.Adaptor, %JSON.Adaptor)
{
/// file data (base64 encoded)
Property Filedata As %String(%JSONFIELDNAME = "filedata");

/// MimeType e.g.

So, you checked your server and saw that IRISTEMP is growing too much. There's no need to panic. Let’s investigate the issue before your storage runs out.

Step 1: Confirm the IRISTEMP Growth Issue

Before assuming IRISTEMP is the problem, let’s check its actual size.

Check the Free Space

Run the following command in the IRIS terminal:

%SYS>do ^%FREECNT

When prompted, enter:

Database directory to show free space for (*=All)? /<your_iris_directory>/mgr/iristemp/

If the output shows very low free space, IRISTEMP is filling up your storage like an overstuffed closet.

When we create a FHIR repository in IRIS, we have an endpoint to access information, create new resources, etc. But there are some resources in FHIR that probably we wont have in our repository, for example, Binary resource (this resource returns a document, like PDF for example).

I have created an example that when a Binary resource is requested, FHIR endpoint returns a response, like it exists in the repository. 

First of all, we need a Namespace and a FHIR endpoint. After this, we need to configure an Interoperability production that will be connected to the FHIR endpoint.

Introduction

My guess is that most IRIS developers create their applications using its native ObjectScript language or, if using an external language, then most likely using either Java, Python or perhaps C++.

I suspect that only a minority have considered using JavaScript as their language of choice, which, if true, is a great shame, because, In my opinion and experience, JavaScript is the closest equivalent to ObjectScript in terms of its ability to integrate with the IRIS's underlying multi-dimensional database.

Hello
This article follows up on the question I had asked the community UDP Adapter not working
In this article, I will present to you
1) What is "UDP"?
2) The current state of Iris with UDP
3) My solution with the UDP adapter

1) What is "UDP"?

UDP stands for User Datagram Protocol. It is one of the core protocols of the Internet Protocol (IP) suite, used for transmitting data over a network. Here are some key features of UDP:

1. Connectionless: UDP does not establish a connection before sending data, which means it can send messages (datagrams) without prior handshaking.

Mirror Your Database Across the Galaxy with Seeding

Hello cpf fans!  This distraction I used the "seed" capability in IRIS to provision an entire IrisCluster mirror, 4 maps wide with compute starting from an IRIS.DAT in a galaxy far far away.  This is pretty powerful if you have had a great deal of success with a solution running on a monolithic implementation and want it to scale to the outer rim with Kubernetes and the InterSystems Kubernetes Operator.  Even though my midichlorian count is admittely low, I have seen some hardcore CACHE hackers shovel around DATS, compact and shrink and update their ZROUTINES, so this same approach could also be helpful shrinking and securing your containerized workload too.  If you squint and feel all living things around you,  you can see a glimpse of in place (logical) mirroring in the future as a function of the operator and a migration path to a fully operational mirrored Death Star as the workload matures.

High-Performance Message Searching in Health Connect

The Problem

Have you ever tried to do a search in Message Viewer on a busy interface and had the query time out? This can become quite a problem as the amount of data increases. For context, the instance of Health Connect I am working with does roughly 155 million Message Headers per day with 21 day message retention. To try and help with search performance, we extended the built-in SearchTable with commonly used fields in hopes that indexing these fields would result in faster query times. Despite this, we still couldn't get some of these queries to finish at all.

Introducing IRIS DocDB Explorer: A Sleek UI for Managing JSON Documents in InterSystems IRIS

IRIS offers a dedicated feature for storing and retrieving JSON documents using DocDB, without requiring a predefined schema.

Developers often need a quick and intuitive way  to browse, create, and edit documents without switching between multiple tools or writing repetitive code. To solve this, I created iris-docdb-ui — a CSP-based open-source application that provides a clean, responsive interface for interacting with DocDB effortlessly.

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.

Disclaimer: This guide is a good fit for Interoperability projects. When you have integrations, data flows, when you use IRIS for ETL processes, etc. Overall, when your code is combined with Productions.
