The most upvoted idea on the InterSystems Ideas Portal—garnering 74 votes—requests a lightweight version of IRIS. While the platform has grown into a powerful data engine, many projects require only its SQL database capabilities. This article demonstrates how to build an unofficial, compact IRIS Community Edition image focused solely on core database functionality, reducing the image size by over 80%.

⚠️ Disclaimer

This project produces an unofficial, experimental image of InterSystems IRIS Community Edition.

• Not supported or endorsed by InterSystems.
• Use at your own risk. The modifications remove core platform features and may break compatibility with tools, APIs, and expected behaviors.
• No warranties or guarantees apply, including fitness for production use.
• Intended only for educational and experimental purposes by advanced users.

Why a Lightweight IRIS?

While IRIS today includes rich functionality—interoperability, analytics, machine learning, system management, etc.—many projects only require its core SQL capabilities. The official Community Edition Docker image is approximately:

• Disk usage: 3.5–3.8 GB
• Compressed size: ~1.1 GB

IRIS Light reduces that to:

• Disk usage: ~575–583 MB
• Compressed size: ~144–148 MB

This makes it suitable for:

• Microservice or containerized SQL use
• CI pipelines with faster startup and pull
• Horizontal scaling where full features are unnecessary

Hello, Community:

How

Hello Community,

Great news for developers who have just started working with InterSystems IRIS! We have hands‑on interactive tutorials available via the Instruqt platform! These are perfect for getting up to speed quickly, playing in real environments, and building confidence with IRIS‑based development.

Here is the list of available tutorials:

• Full Stack Tutorial - Experience how IRIS supports full-stack system architecture.
• InterSystems Interoperability - Explore IRIS interoperability tools for connecting and integrating systems.
• IRIS for Health Interoperability - Learn to use IRIS for Health features in application integration with data from an EHR (Electronic Health Record).
• REST + Angular Application - Practice building applications with IRIS REST services.
• RAG using IRIS Vector Search - Discover IRIS Vector Search capabilities for AI-powered applications.

Inevitably, you will eventually need to move your code up from one version of IRIS or Cache to a more recent version of IRIS. There are a few good steps you can take to set yourself up for success in that process.

I am trying to add some validation to an existing Record Map, because recently we had some wrong data get consumed into the System and is causing all kinds of havoc.

Using the AI on the Developer community it suggested that I use PATTERN within the Datatype Parameters to force some validation on some fields. I have never used PATTERN before...

When I go to generate the updated Record Map, I am getting the following...

The 2025.3 release of InterSystems IRIS® data platform, InterSystems IRIS^® for Health, and HealthShare^® Health Connect is now Generally Available (GA). This is a Continuous Delivery (CD) release.

Release Highlights:

Studio's Output window is interactive, and code can ask questions there if it is a Studio environment. How do I check for that?

A previous attempt was assisted by an external Python method.
This is all classic CSP written with ISOS, JavaScript, HTML

Besides the graphic, you also get concrete numbers freshly collected from your local
instance or from remote instances that also installed the package.

The final result

I have a locally saved multiple saved .cls file. How can I bundle them together as a XML file programmatically (ObjectScript) so that I can import in the next environment. Does anyone have a sample code?

As part of improvements regarding CCR usage and usability, certain transitions are now blocked when a CCR Record has undeployed ItemSets for required Environments.

In today’s healthcare data landscape, FHIR has become the standard for structured clinical data exchange. However, while FHIR excels at interoperability, its JSON format makes analytics challenging—including FHIR QuestionnaireResponse.

Hola amigo! 😊 Cómo estás hoy,

I would like to share a small part of my learnings from my first ever official project: POS/EDC machine integration with our billing system. This was an exciting challenge where I got hands-on experience working with APIs and vendors.

How does a Payment Machine actually work?

It's simple, start by initiating/creating a transaction, then retrieve its payment status.

Here, initiate/create refers to POST method and Retrieve refers to GET.
