In the process of trying to get more familiar with Objectscript I decided to try to build a general priority queue since I wasn't able to find an implementation anywhere. My though process for implementing this followed this general path.
As of InterSystems IRIS® data platform version 2025.1, InterSystems is officially deprecating MultiValue and including it in the Deprecated and Discontinued Features list.
The first developer previews of InterSystems IRIS® data platform,InterSystems IRIS® for Health, and HealthShare® Health Connect 2025.1 have been posted to the WRC developer preview site. Containers can be found on our
February 19, 2025 – Alert: SQL Queries Returning Wrong Results
InterSystems has corrected two issues that can cause a small number of SQL queries to return incorrect results. In addition, InterSystems has corrected an inconsistency in date/time datatype handling that may lead to different, unexpected – yet correct – results for existing applications that rely on the earlier, inconsistent behavior.
DP-436825: SQL Queries with Lateral Join May Return Wrong Results
The IKO allows for sidecars. The idea behind them is to have direct access to a specific instance of IRIS. If we have mirrored data nodes, the web gateway will (correctly) only give us access to the primary node. But perhaps we need access to a specific instance. The sidecar is the solution.
Building on the example from the previous article, we introduce the sidecar by using a mirrored data node and of course arbiter.
All pods are assigned a Quality of Service (QoS). These are 3 levels of priority pods are assigned within a node.
The levels are as following:
1) Guaranteed: High Priority
2) Burstable: Medium Priority
3) BestEffort: Low Priority
It is a way of telling the kubelet what your priorities are on a certain node if resources need to be reclaimed. This great GIF below by Anvesh Muppeda explains it.
Below we define the environment we will be creating via a Custom Resource Definition (CRD). It lets us define something outside the realm of what the Kubernetes standard knows (this is objects such as your pods, services, persistent volumes (and claims), configmaps, secrets, and lots more). We are building a new kind of object, an IrisCluster object.
InterSystems has corrected a defect that causes invalid database and journal records to be introduced when using a specific $LIST syntax. The likelihood of encountering this defect is very low but the operational impacts can be significant.
The InterSystems platforms have always offered dynamic documentation of the packages and classes in a namespace, a feature known informally as Documatic. But what if you need to publish this class reference information on a website without requiring the site to be connected to an IRIS server containing the actual classes?
A benefit of using Doxygenerate is that Doxygen does more than just HTML output. Tweak the Doxyfile that tells Doxygen what to do and you can easily create a PDF. Our example MARINA application yielded a 524-page PDF. Here's what page 94 looks like:
An extension “extends” or enhances a FHIR resource or a data element in a custom way. The extension can be added to the root of a resource, such as “Patient.ethnicity” in US Core profile, and they can be added to individual elements such as HumanName, Address or Identifier.
Did you know that you can also add an extension to a primitive data type?
Primitives usually store a single item and are the most basic element in FHIR. For example: "Keren", false, 1234, 12/08/2024 etc.
For example, the patient resources might look like this:
IAM - InterSystems API Manager is a great tool for monitoring your traffic. If you are trying to use it in your Kubernetes cluster you may have tried doing a deployment similar to this one:
I am accessing IRIS databases with JDBC (or ODBC) using Python. I want to fetch the data into a pandas dataframe to manipulate the data and create charts from it. I ran into a problem with string handling while using JDBC. This post is to help if anyone else has the same issues. Or, if there is an easier way to solve this, let me know in the comments!
I am using OSX, so I am unsure how unique my problem is. I am using Jupyter Notebooks, although the code would generally be the same if you used any other Python program or framework.
For those of you who still use the Studio IDE for ObjectScript programming and are going through the process of migrating to VS Code, did you know there's a section in the VS Code documentation just for you? Have a look at the Migrating from Studio chapter. It covers:
Considering new business interest in applying Generative-AI to local commercially sensitive private data and information, without exposure to public clouds. Like a match needs the energy of striking to ignite, the Tech lead new "activation energy" challenge is to reveal how investing in GPU hardware could support novel competitive capabilities. The capability can reveal the use-cases that provide new value and savings.
Sharpening this axe begins with a functional protocol for running LLMs on a local laptop.
As part of the InterSystems Solutionathon we would like to distribute a very quick survey on your thoughts on using AI-driven code documentation for ObjectScript.
We are excited to announce a new part of InterSystems documentation that makes it easier to upgrade InterSystems IRIS® data platform, InterSystems IRIS® for Health™, or HealthShare® Health Connect. The Upgrade Impact Checklist at https://docs.intersystems.com/upgrade shows you all the things you need to consider – and only the things you need to consider – in an upgrade between any two versions.
With the world (as well as our own technology) moving to the cloud at such a fast pace it is easy (at least for myself) to get caught up in the little details. One thing I, and some clients of ours, had run into a couple of times was the necessity to specify the version of the images one plans to use with the IKO.
I had attempted to create a REST Operation before but did not have success. As I am going through the Tutorials and Documentation everything references REST services, but I have a case where I want to create a REST Operation that makes Epic API calls against Interconnect. I have done SOAP operations before and we currently have one in our Production Namespace, but from what I understand SOAP has the wsdl which defines al the structures and etc, where REST does not.
