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:

I am working on a tool that configures an instance to use a common default routine database across all custom Namespaces. For instances that already have distinct default routine databases for their Namespaces, this would involve a step of merging over all code from the current default routine databases to the new "super" routine database. This should be done in such a way that only merges contents in the default routine database (not mapped databases) and is able to detect/exclude contents that already exist in the target database.

I seem to remember making this work before, but I'm not having any luck digging up examples.

I've defined some custom properties for a business operation that could definitely benefit from having popup descriptions available in the Production Configuration. I have triple-slash comments before each property that do just that in the source. I thought those provided the text for the popup descriptions when clicking on the property name, but apparently not.

Any thoughts?

Is it possible to audit code changes in a namespace?

Ideally what we'd like to be able to do is check which classes were compiled (or deleted) in a time period, eg in last 3 months, and which user made those changes. Even better would be an audit of what those changes were, but that's less important (for us, as we can probably find that information in other ways).

I have a primary dispatch class that implements %CSP.REST.AccessCheck() for some high level access checks before the route table forwards the request to the implementation classes which also implement %CSP.REST.AccessCheck() for some lower level access checks. The idea is that we know where we are in the implementation class and what the user is trying to do, so it makes more sense to check some lower level items there rather than trying to parse out the request at the dispatch class.

The following CPF entry:

[Actions]
CreateUser:Name=foobar,Roles=%All,Password=loremipsumdolorsitamet1234,FullName=Foo Bar,ChangePassword=1,Enabled=1,Comment=Testing testing,AccountNeverExpires=1,PasswordNeverExpires=1

Fails with an error:

ERROR #506: Invalid property error at line 19, 'Password=loremipsumdolorsitamet1234', Class Security.Users, Error=<CANNOT SET THIS PROPERTY>zPasswordSet+3^Security.Users.1

A bug or a feature or a stupid user error? The documentation says nothing about the limitations:

We've got some web services that utilise EnsLib.SOAP.Service/EnsLib.REST.Service. These do some further requests to a few operations to call some other services and return the combined results.

An issue that we are noticing is that some of the usage involves users hitting the refresh button a few too many times and generating a lot of requests. This is mostly an issue when the service that the operations are calling are down or slow to respond. IRIS starts using a lot of RAM when this occurs and has caused outages by getting through an extra 50-60GB of RAM.

Hi Developers!

With InterSystems IRIS Cloud SQL recently becoming Generally Available, some of you may have had a chance to try it out. Or maybe you used it for your contest entry or during the EAP period. We're curious to learn what YOU think of it. So, have you already tried the new service InterSystems IRIS Cloud SQL?

We have launched a new Ideas Portal category dedicated to this database-as-a-service (DBaaS) where we're looking for your ideas on how we can improve InterSystems IRIS Cloud SQL.

Or share your experience with the service in the comments to this post.

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.

Hello All,

I have used github (outside of IRIS) for many many years and have no problem with it. Also used SVN and other source control systems.

I have a conceptual problem understanding the ISC github links and how they work via VSCode.

Our server is on Linux.

What I've done:

1. On Linux Server - d ##class(SourceControl.Git.API).Configure()

I am a first time Python Contest participant and am interested in potentially implementing the community idea found in https://ideas.intersystems.com/ideas/DPI-I-542 if it is something relevant to Python.

Would anyone be able to shed a bit of light on what the desired outcome of that idea being implemented is? There were a lot of upvotes on that idea but there wasn't very much information in it. Thanks!
