Has anyone been able to successfully implement a business service to pull files from Azure Blob storage?

In Part 1, we explored how window functions operate. We learned the logic behind PARTITION BY, ORDER BY, and such functions as ROW_NUMBER() and RANK(). Now, in Part 2, let's delve into more window functions with practical examples.

1. Aggregate-over-Window Functions

Overview

These functions compute an aggregate (e.g., sum, average, min, max, count, etc.) over the defined window frame but don’t collapse rows.
Each row remains visible, augmented with aggregated values for its partition.

Supported functions include the following:

• AVG() — average of values in the window frame.
• SUM() — total of v

Parallel query hinting boosts certain query performances on multi-processor systems via parallel processing. The SQL optimizer determines when this is beneficial. On single-processor systems, this hint has no effect.

Parallel processing can be managed by:

1.  Setting the auto parallel option system-wide.
   

2. Using the %PARALLEL keyword in the FROM clause of specific queries.
   

%PARALLEL is ignored when it applied to:

1. INSERT, UPDATE, and DELETE queries (Only SELECT queries benefit from this feature)
2. The queries involving process-specific functions or variables
3. A subquery correlated with an encl

Since the introduction of Embedded Python there has always been doubt about its performance compared to ObjectScript and on more than one occasion I have discussed this with @Guillaume Rongier , well, taking advantage of the fact that I was making a small application to capture data from public competitions in Spain and to be able to perform searches using the capabilities of VectorSearch I saw the opportunity to carry out a small test.

How do I take SVG data to be an image in Logi Reports? Now I can take JPG data and render it in Logi Reports. And I can take the SVG data in ObjectScript, but when I view it in Logi Reports, it won't appear. How do I get the code in ObjectScript to appear and be read in Logi Reports?

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.

Read Documentation Carefully

Before you move anything you should check out the IRIS documentation page for many useful resources on changes made to various versions of IRIS. If you are upgrading through multiple versions, you will want to check on the documentation for all of them, not just the version to which you will upgrade. For each version, if you click on the Maintenance Rel

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.

Hi community!

I am excited to say that since the beginning of this year we have published many of the client SDKs for InterSystems IRIS, InterSystems IRIS for Health and Health Connect to the corresponding external repositories (Maven, NuGet, npm and PyPI). This provides many benefits to you such as:

• You can access the latest releases for a client SDK as soon as they get published, independent of the InterSystems IRIS release cadence
• You can integrate the SDKs as a dependency with the native package manager tool within your ecosystem and manage dependencies in an industry-standard way

Hi,

When we open a terminal in IRIS, we are entering the ObjectScript shell. Within this shell, we can execute IRIS commands, such as:

In other words, the ObjectScript command is executed in the current shell. But it's always good to remember that IRIS has other shells

• SQL
• Python
• TSQL
• MDX

One very interesting aspect is shortcuts. We can access these shells through their calls or via shortcuts, as shown in the table below:

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

To promote best practice, when a Tier 1 or Tier 2 CCR moves between Environments, it is important that ItemSets are deployed to required Environments before confirming that the CCR has successfully been implemented in the next Environment. Previously, when progressing a CCR from one Environment to the next, users were not required to deploy ItemSets before performing markMoveToXXXXComplete or markCANCELComplete transitions. Now

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.

IRIS 2023.3.0 ASQ

Abstract Set Query, ASQ, is a super set of JSON Path Language, JPL, which was first introduced by the 2016 ISO SQL Standard. JPL is only defined within the context of SQL. In 2023.3, we introduced classes that implement ASQ. It works on any implementation of %Library.AbstractSet. The complete syntax for ASQ will be documented later. This is just a quick introduction to a few of its features. This implementation comes with a nice utility as well. You will know it when you see it!

For developers building external applications, especially those using familiar technologies like C#, ODBC (Open Database Connectivity) is a crucial, standardized bridge to any relational database, including InterSystems IRIS. While InterSystems offers its own native ADO.NET provider, the ODBC driver is often the most straightforward path for integration with generic database tools and frameworks.

Here is a step-by-step guide to getting your C# application connected to an IRIS instance using the ODBC driver, focusing on DSN-less connection string.

Step 1: Install the InterSystems IRIS ODBC Driver

The InterSystems ODBC driver is installed by default when you install InterSystems IRIS on a Windows machine.

• If IRIS is on the same machine: The driver is already present.
• If IRIS is on a remote server: You must download and install the standalone ODBC client driver package for your client operating system (Windows, Linux, or macOS) and bitness (32-bit or 64-bit) from WRC website if you're a client or by installing Client components and copying ODBC driver.

Once installed, you can verify its presence in the ODBC Data Source Administrator tool on Windows (look for the InterSystems IRIS ODBC35 driver).

Hi everyone,
I'm getting prepared to take the following certification exam: "InterSystems IRIS Development Professional".

Can you give some advice on how to prepare (aside from the official course page: https://www.intersystems.com/certifications/intersystems-iris-development-professional/ )?
Do you have examples of quiz questions that simulate the real exam or any material that helped you getting prepared?

Thanks you in advance,

Hello 

I'm using from visual code. My routines are server-side files. If I try to search patterns in files (e.g find all routines containing the string "version=3") , the search runs but didn't find anything. If I do the same search from the management portal, it finds all routines including this pattern with a good performance.

Modern data architectures utilize real-time data capture, transformation, movement, and loading solutions to build data lakes, analytical warehouses, and big data repositories. It enables the analysis of data from various sources without impacting the operations that use them. To achieve this, establishing a continuous, scalable, elastic, and robust data flow is essential. The most prevalent method for that is through the CDC (Change Data Capture)  technique. CDC monitors for small data set production, automatically captures this data, and delivers it to one or more recipients, including analytical data repositories. The major benefit is the elimination of the D+1 delay in analysis, as data is detected at the source as soon as it is produced, and later is replicated to the destination.

This article will demonstrate the two most common data sources for CDC scenarios, both as a source and a destination. For the data source (origin), we will explore the CDC in SQL databases and CSV files. For the data destination, we will use a columnar database (a typical high-performance analytical database scenario) and a Kafka topic (a standard approach for streaming data to the cloud and/or to multiple real-time data consumers).

Overview

This article will provide a sample for the following interoperability scenario:

Hi developers!

How do you debug implementation code in .impl classes of REST.API in InterSystems IRIS?

Especially if you don't have access to globals, so no things like: 

Set^AAA="here we are"

not possible in this case.

Suppose I have the following signature of the REST.API method called as POST and containing JSON. :

In my previous article, I structured network communications
in these 3 possible layers, and covered the last

• Client <---> Transport
• Server <---> Transport
• Client <---> Server

In fact, you have the most control over the last one.
The IRIS side as a server is yours and under your full control. 
Up to now, the Transport layer was assumed to be as passive as a bare wire.

This assumption should be verified. I once met a Windows environment with
a quite surprising setup where a Firewall-like filter was isolating internal
processes and causing a lot of trouble.

? What can you do about the  Trans

Chasing errors or misbehavior in the network can be quite a challenge.
Differently to  a local application on the DB server, you always have at least 3 players:

• A client  to place a request 
• some kind of transport layer
• and a server to provide a reply.

This results in a minimum of 3 possible communication layers

• Client <---> Transport
• Server <---> Transport
• Client <---> Server

The last one is probably the easiest  to check, while the other 
two deal with the same counterpart just from opposite sides.

?  Do both ends use the same communication protocol ?
