Introduction to Interoperability on Python (IoP) - Part3

Hi Community,

In our two preceding articles, we explored the fundamentals of the Interoperability Embedded Python (IoP) framework, including message handling, production setup, and Python-based business components.

In this third piece, we will examine advanced methodologies and practical patterns within the IoP framework that are pivotal for real-world interoperability implementations.
We will explore the following topics: 

✅ DTL (Data Transformation Language) in IoP
✅ JSON Schema Support
✅ Effective Debugging Techniques

Collectively, these features help us create maintainable, validated, and easily troubleshootable production-grade interoperability solutions.

The PACELC theorem and the InterSystems IRIS

The PACELC theorem was created by Daniel Abadi (University of Maryland, College Park) in 2010 as an extension of the CAP theorem (created by Eric Brewer - Consistency, Availability, and Partition Tolerance). Both help design how to architect the most suitable operation of data platforms in distributed environments under the aspects of consistency versus availability. The difference is that PACELC also allows analysis of the best option for non-distributed environments, making it the gold standard for considering all possible scenarios to define your deployment topology and architecture.

The CAP theorem states that in distributed systems, it is not possible to have consistency, availability, and partition tolerance simultaneously, requiring a choice of two out of three, according to the following diagram.

CREATE TABLE from another server query

hi 😊,

i'm able to LOAD DATA in IRIS from a rather complex, say Oracle's, query. It works pretty well but requires a target table created aforehand:

LOAD DATA FROM JDBC CONNECTION SOME_OTHER_SERVER QUERY 'complex query here' INTO TargetTable

is there a way to base such target table on the same query ? 
CREATE FOREIGN TABLE seems to require a column definition which I would prefer to be taken from the query
CREATE TABLE AS SELECT seems to be for local queries and other methods, like Linked Table Wizard or %SYSTEM.SQL.Schema.

EnsLib.EDI.ASTM.Service.TCPService — CELL-DYN Ruby Link Test fails with EOTOPTIONAL=1, instrument shows Status DOWN despite ACK being sent

Hello,

I am working on integrating a CELL-DYN Ruby hematology analyzer (Abbott) with InterSystems Ensemble using the ASTM E1394 protocol over TCP/IP via a Digi One SP serial-to-TCP converter. I am facing a persistent issue where the Link Test keeps failing on the CDRuby side and the Transmit button remains greyed out. I have overridden EOTOptional=1 in the service class file as Ensemble was not able to send ACK after ENQ. Now I am getting below logs like Machine sends ENQ, Ensemble sends back ACK and Machine sends EOT instead of STX.

IRIS Cloud Document - Beginner Guide & Sample : Part I - Intro and Quick Tour

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.

In this article pair I’ll walk you through:

  • Part I - Intro and Quick Tour (this 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 (the next 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

The goal is to give you a smooth “first run” experience.

IRIS BI Dependent Cube Update Changes

Starting with InterSystems IRIS 2025.1, the way dependent cubes are handled in cube builds and cube synchronizes was changed.

This change may require modifying custom build/synchronize methods. If you are using the Cube Manager, these changes are already considered and handled, which means no action is needed.

Prior to this change, cubes were required to be built and synchronized in the proper order and account for any cube relationships/dependencies. With this change, dependent cubes are automatically updated as needed when using the %BuildCube or %SynchronizeCube APIs.

Using InterSystems Server VSCode extension in client side mode with projects

Hi everyone,

I was wondering if it is possible to use the InterSystems Server VSCode Extension to work in client side mode but importing locally the content of a project without having to choose the files manually.

It would be awesome to have all project-related assets synchronized in one go. Relying on InterSystems Projects (.prj files) would be convenient for several reasons:

  1. Projects bundle different file types (CLS, MAC, INT, CSP). Importing the project as a whole is much more efficient than picking individual files piece by piece.

Embedded Python programming with Claude Code: A bit of a trap

Claude Code has a strong understanding of IRIS, but unexpected issues still occur.

The first issue is one that has already happened several times and is likely to continue occurring if not properly addressed.

In IRIS, the collation for string data (%String) is set to SQLUPPER by default. As a result, when data is retrieved via SQL, it may be returned in uppercase (for example, when sorting and aggregating with GROUP BY).

Building a dynamic Object: how can I use variables?

Hi developers!

In a method I need to return a result as a dynamic object aka JSON Object. And here is my logic:

Classmethod Planets() as %DynamicObject {

 set val1="Jupiter"
 set val2="Mars"
// this doesn't work! cannot compile
 return {"value1":val1, "value2":val2}

}

So I need to do the following:

Beginner's Guide to %JSON and Dynamic Entities in IRIS

Dynamic Entities (objects and arrays) in IRIS are incredibly useful in situations where you are having to transform JSON data into an Object Model for storage to the database, such as in REST API endpoints hosted within IRIS. This is because these dynamic objects and arrays can easily serve as a point of conversion from one data structure to the other.

Embedded Python Programming with Claude Code

Since I started using Claude Code, my motivation to create things has skyrocketed.

Previously, even if I wanted to build something, actually doing the coding felt like a hassle, so unless there was a very strong need, I rarely went as far as programming. But now, if I just jot down the specifications, Claude Code handles the rest automatically, resulting in a dramatic improvement in productivity.

I come from a generation native to ObjectScript, so I used to feel some hesitation when it came to switching to Python.

Migrating InterSystems Studio/Caché and Visual Studio Code Setup to a new Windows PC

Recently, I replaced my old laptop with a new one and had to migrate all my data. I was looking for a guide but couldn’t find anything that explained in detail how to migrate server connections from InterSystems Studio and Visual Studio Code from one PC to another. Simply reinstalling the tools is not enough, and migrating all the connections manually seemed like a waste of time. In the end, I managed to solve the problem, and this article explains how.

InterSystems Studio

Exporting Server Connections

Migrating Studio connections was the most challenging part.
