The Power of Indexing in Database Tables

When working with databases, most developers understand the concept of an index and why it's used: to speed up data retrieval. But the real impact of indexing often becomes clear only when you compare scenarios with and without it.

Do you Know what Happens Without an Index?
Imagine a table with three columns: Name, Age, and MobileNumber.

We have created a CSP application in the path /csp/ourapp. Due to some session handling issues, we created a new web application /csp/ourapp/hl7mapping that points to the sane namespace, and we now access the CSP pages using this new URL. This works fine in the local system.

After deploying the app to server, we are facing issues around compiling CSP pages.

I am experimenting with OpenTelemetry and recently connected all IRIS instances to telemetry servers.
I'm not interested in emitting custom metrics since IRIS does it fine, regarding tracing - we can use %Trace classes to emit custom traces, but what about logging?

I see that IRIS is able to send system log messages to the OpenTelemetry servers:

Cache Studio Debugger

Hi,

I have Cache 2024.1. I attached the process ID from my terminal to the Cache Studio for Debugger. When I click on "Call Stack" tab I only see first 500 shown. Anyone know how to extend so I can see the rest of the information when i click on "Call Stack" tab? Thank you very much.

Second question: Using Cache Studio Debugger, anyone know how to expand the value of this variable when it display F,...

Time for another round of code golf!

Develop a function that performs a two-step encryption process on a given string:

  • First Step: Reverse Cipher

    • Reverse the entire input string.
    • Relocate the last character of the original string (now the first character of the reversed string) to the end.

  • Second Step: Alphabetic Index Binary Encoding

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:

In this article, we will discuss all the debugging tools included in the Microsoft Visual Studio Code IDE.

What will be covered:

  • Breakpoints
  • Watch window
  • Call Stack

Let's start by learning about debugging requirements!

Prerequisites

There are two plugins (extensions) for debugging ObjectScript:

The first is part of the InterSystems ObjectScript Extension Pack. The second is Serenji, a standalone plugin that provides an editor, file manager, and debugging functionality. Both plugins can be installed from the plugin store. To activate key functionality, Serenji requires a license. For this article, we'll use the InterSystems ObjectScript Extension Pack to reduce the learning curve. After you've mastered the basics, you can consider purchasing a paid license for Serenji.

Hello community!
I have a small challenge for you :)

One of customers is sending quite a lot of messages between interoperability components, which mix standard request content and streams representing serialized JSON objects. As these JSON streams can be quite long (but not too long, just couple hundreds of characters) they would appreciate if the JSON content of stream was displayed in a nice-to-read way, using syntax highlighting by message trace view.

Hi everyone.

I'm going to give you a quick tip on how to implement an AI agent to search the Intersystems documentation integrated into Teams.

Yes, I know the documentation page has its own AI search engine and it's quite effective, but this way we'd have faster access, especially if Teams is your company's corporate tool.

You can also create another AI agent to search articles published in the developer community (which also has its own integrated AI search engine).

Hi,

We’re launching an Early Access Program for an upcoming Table Partitioning feature that will help IRIS customers manage very large tables, and distribute row data and associated indices across databases and storage tiers. Table Partitioning cuts deep into the core of IRIS relational data management, so we want to make sure we get things right through working with a few engaged customers who can provide feedback on the initial deliverables, and fine-tune as needed.

I want to extract data from IRIS (Health Share Provider Directory) and write the data out to a file that I can use within an external system. Using EnsLib.SQL.Service.GenericService do I need to supply Credentials if I am querying IRIS locally? I have always used JDBC to connect externally when creating Services and Operations to read/write SQL data from external Databases, but never internally. Normally I would just use sql or code to pull the data within a Process or DTC. But in this case, I want the Service to drive the workflow, and query the data from Local Tables

Hello everyone.

I have a question regarding the priority when applying a default configuration.

I have several Business Services that use the same class, so I want them all to have a common "Schedule" configuration.

However, there's one that I don't want this default configuration applied to, so I've tried setting the Schedule value to empty for that element based on its name:

In this case, the elements that use the class Kurro.BS.SFTP.Marca have the default value "CargaFicheros".

I have an Embedded Python method, which is essentially a call to one third-party module.

Most of the time, the method takes <0.1 seconds to execute, but sometimes it takes 30 or 60 seconds.

The server is relatively idle (20-30% CPU load).

How can I debug this issue further? Ideally, I want to know where this library spends the time. The library is mainly Python code (it's boto3, so it's not a Python C API proxy library).

Introduction.

In this article, we'll cover a quick start to Git development with the InterSystems Developer Community and version control practices when working with IRIS InterSystems. We'll cover scenarios where we need to export Interoperability classes, globals, and analytics elements such as cubes and dashboards. These scenarios encompass key version control practices with IRIS.

To get started, you'll need:

  1. Register and log in to GitHub
  2. Be a member of the intersystems-community organization on Git

Getting started with IRIS InterSystems is very simple!
