Ingestion and Querying Speed Test

The capacity of taking numerous records every second while also facilitating real-time queries simultaneously in real time is called Hybrid Transactional Analytical Processing (HTAP). It is also called Transactional analytics or Transanalytics or Translytics and is a very useful element in scenarios where there is constant flow of real time data coming from IIOT sensors or data on fluctuations in stock market, and supporting the need for querying these data sets in real-time or near real-time.

Hi,

I have a method that has multiple parameters and is normally used from other classes in ObjectScript. Most of the parameters have default values. Withing the server code that's perfect. In some areas I can call myMethod(,,"sometext") or myMethod(tVariab) and thats fine... I use it as it's required in each place.

But now I want to expose it as a REST service so I need to buld a kind of wrapper., another method in a REST dispatcher class that will receive the parameters in a JSON object and will call the server method already implemented. Something like:

Hi folks,

One of my clients want to project a null property of a cache object to an empty XML element. Say, if we have a class:


Class Diabetes.BS.Message.LabReportMessage Extends Ens.Request
{

Property Report As %String;

Property IsRisky As %Boolean;

Property RiskValue As %String ;

}


If the instance of this class has a null RiskValue, after projection, they want the XML as following:

InterSystems has decided to stop further development of the InterSystems IRIS Natural Language Processing, formerly known as iKnow, technology and label it as deprecated as of the 2023.3 release of InterSystems IRIS. InterSystems will continue to support existing customers using the technology, but does not recommend starting new development projects outside of the core text exploration use cases it was originally designed for.

There's a new and exciting enhancement to QEWD that has just been released - it's an additional layer of abstraction known as QEWD-Up. QEWD-Up hides away all the mechanics of QEWD itself, allowing you to focus on just your REST APIs and the code that implements them.

Additionally, and importantly, QEWD-Up simplifies the maintenance of your REST APIs, allowing you (and others) to quickly and easily understand their life-cycle and implementation.

Atelier Users:

Has anyone found an Eclipse plug-in that provides the capability to connect to a Caché server and give the user a way to write SQL queries using the tables from that server? I'm picturing something like a "WinSQL"-client built as an Eclipse plugin.

I've found and tried the following, but I couldn't get it to connect to my local Caché instance.

Hi,

I am trying to install Intersystems IRIS Health Community On Windows 10 Pro version. I am getting 112 error while installing and in some point it Roll Back the Action.

But I am able to configure in Windows 10 Enterprise version.

Is any other settings are there to configure in Windows 10 Pro version or IRIS is not supported?

Please help me.

Thanks in advance.

Keywords: IRIS, IntegratedML, Machine Learning, Covid-19, Kaggle

Purpose

Recently I noticed a Kaggle dataset for the prediction of whether a Covid-19 patient will be admitted to ICU. It is a spreadsheet of 1925 encounter records of 231 columns of vital signs and observations, with the last column of "ICU" being 1 for Yes or 0 for No. The task is to predict whether a patient will be admitted to ICU based on known data.

InterSystems IRIS 2020.1 brings a broad set of improved and new capabilities to help build important applications. In addition to the many significant performance improvements accrued through 2019.1 and 2020.1, we are introducing one of our biggest changes in recent SQL history: the Universal Query Cache. This article provides more context on its impact to SQL-based applications at a technical level.

Tar compress tool in ObjectScript

I'm sure most of you have already familiar with the possibility of using GZIP in InterSystems products. But, the problem is that GZIP working only with one file or stream, and it does not support folders. When you work in Unix systems, there is a possibility how to solve it, using tar compress tool which goes with every Linux system from out of the box. But what to do if you have work on Windows as well, which does not have it.

I am pleased to offer you my new project isc-tar, which will help you do not care about operating system, and deal with tar files anywhere.

Simple WorkMgr example

Attached code contains a very basic $system.WorkMgr example.

It uses several jobs (workers) to update different chunks of rows of a table.

Steps:

  • Creates a table with 100 records.
  • Split table in chunks
  • Initialize WorkMgr and queue chunks to workers.
    • Every worker simply sets its process number in the Job field of the processed row.

In this case, I have tested the example in a 8-core laptop:

We will be transitioning from a server running HP OpenVMS to one running RHEL 7. The main question some of the team had was what would be the best method for moving the globals to the new system.

Also, I was wondering if any others have transitioned from OpenVMS to RHEL. If so, were there any kinks that we should be aware of prior to transition?

Find a table given its name

The following code snippet includes a class method "test" that runs code to find a class based on the class's name. "test" takes one argument, which is the name of the table:


Class objectscript.findTable Extends %RegisteredObject
{
    classmethod test(name as %String="mytable")  
    {
            #Dim result as %ResultSet
            #Dim tName as %String
            #Dim contain as %Integer
     
            Set contain=0
            Set result = ##class(%ResultSet).%New("%Dictionary.ClassDefinition:Summary")
            Do result.Execute()

            While(result.Next()) 
            {
                Set tName=$get(result.Data("Name"))
                &sql(select position (:name in :tName) into :contain)
                Write:contain'=0 tName, " ... ", name, " (", contain,")", !
            }
            Return $$$OK
     }
}

Here's a link to the code on GitHub

Right now I have a developer/free version of Cache 2016.1 on my local dev box but it doesn't have Ensemble installed, is there a way to get Ensemble?

After having gone to the 2016 Global Summit I want to play around with it on my own and see what it's capable of.

Thanks

Leveraging the Audit database

The InterSystems IRIS has a great audit system. It is responsible for auditing system events, but you can use it to audit your applications (great feature).

The audit system is based into event concept. The events can occur with IRIS or in an application. So, we have two type of events to the audit system:

1. System events: events occured into the InterSystems IRIS components (database, interoperability, analytics and core);
