In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

  • Git 101
  • Git flow (development process)
  • GitLab installation
  • GitLab Workflow
  • Continuous Delivery
  • GitLab installation and configuration
  • GitLab CI/CD
  • Why containers?
  • Containers infrastructure
  • CD using containers
  • CD using ICM
  • Container architecture

In this article, we would talk about building your own container and deploying it.

Save a file using %Net.HttpRequest

This code snippet allows for a file on the web to be saved into the file system. Specify the server and GET request, as well as the directory the file should be saved to. The class method "test" runs the code:


Class objectscript.saveFileHTTP Extends %RegisteredObject
{
    classmethod test() {
        Set httprequest = ##class(%Net.HttpRequest).%New()
        Set httprequest.Server = "docs.intersystems.com"
        Do httprequest.Get("documentation/cache/20172/pdfs/GJSON.pdf")
        
        Do $System.OBJ.Dump(httprequest.HttpResponse)
         
        Set stream=##class(%FileBinaryStream).%New()
        Set stream.Filename="c:\test.pdf"

        Write stream.CopyFrom(httprequest.HttpResponse.Data)
        Write stream.%Save()
    }
}

Here's a link to the code on GitHub

I already talked about GraphQL and the ways of using it in this article. Now I am going to tell you about the tasks I was facing and the results that I managed to achieve in the process of implementing GraphQL for InterSystems platforms.

What this article is about

  • Generation of an AST for a GraphQL request and its validation
  • Generation of documentation
  • Generation of a response in the JSON format

Market penetration

My understanding is that IRIS is a new technology and does not replace Cache or Ensemble and to that end is more of a modernization than a repackaging. Is that accurate?

Is IRIS and HealthShare heavily penetrated in the payer space of primarily dominate in the provider space? What is the trajectory for InterSystems to penetrate the payer landscape?

Hi, Community!

Continuous Delivery is a software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. It aims at building, testing, and releasing software faster and more frequently. The approach helps reduce the cost, time, and risk of delivering changes by allowing for more incremental updates to applications in production.

Join us at 07:00 UTC, April 24th for a webinar with a live demo "Git flows and Continuous Delivery" by @Eduard Lebedyuk

The language of the webinar is Russian.

Hey folks,

I am new to IRIS and cloud platforms. I've done the InterSystems IRIS Experience on the learning site and read a lot of the online documentation. What I am unable to figure out is which type of package or option you will use on the cloud provider.

AWS for example, has AWS EC2, Elastic Beanstalk and some other products geared towards Docker containers.
Azure has Kubernetes and some other options.

%DOC with DeepSee

Hello,

I have imported my data with the following code (%DocDB).

set filename = "/home/student/Dokumente/convertcsv.json"

IF $SYSTEM.DocDB.Exists("Fitabase1") {

SET db = ##class(%DocDB.Database).%GetDatabase("Fitabase1")

}

ELSE {

SET db = ##class(%DocDB.Database).%CreateDatabase("Fitabase1")

}

set arr = ##class(%DynamicAbstractObject).%FromJSON(filename)

SET jstring = arr.%ToJSON()

//SET doccount = db.%Size()

DO db.%FromJSON(jstring)

Often InterSystems technology architect team is asked about recommended storage arrays or storage technologies. To provide this information to a wider audience as reference, a new series is started to provide some of the results we have encountered with various storage technologies. As a general recommendation, all-flash storage is highly recommended with all InterSystems products to provide the lowest latency and predictable IOPS capabilities.

The first in the series was the most recently tested Netapp AFF A300 storage array. This is middle-tier type storage array with several higher models above it. This specific A300 model is capable of supporting a minimal configuration of only a few drives to hundreds of drives per HA pair, and also capable of being clustered with multiple controller pairs for tens of PB's of disk capacity and hundreds of thousands of IOPS or higher.

In this article, we'll build Continuous Delivery with InterSystems Cloud Manager. ICM is a cloud provisioning and deployment solution for applications based on InterSystems IRIS. It allows you to define the desired deployment configuration and ICM would provision it automatically. For more information take a look at First Look: ICM.

Hi everyone,

I am still learning the platform for a student project and have to do some streaming and data analysis next. Since for my case I have no "live api" I wanted to just stream json files and output the data as it comes in from the files. (basically to emulate a incoming data scenario)

So thanks to the documentation and community posts I have figured how to create a stream and read data from a JSON but since I'm also new to JSON I have some parsing problems. I don't know how to access subarrays/sub-objects via objectscript.
