Hi Community,

We are pleased to invite all the developers to the upcoming InterSystems Globals Contest Kick-off Webinar! The topic of this webinar is dedicated to the Globals contest.

In this webinar, we’ll show you how to deal with Globals to implement different data models and sophisticated indexes. As always, our experts will answer the questions on how to develop, build, and deploy Globals solutions using InterSystems IRIS.

Date & Time: Monday, March 21 – 11:00 AM EDT

Speakers:
🗣 ​​​@Daniel Kutac, Senior Sales Engineer
🗣 @Joel Solon, Senior Technical Trainer
🗣 @Timothy Leavitt, Development Manager
🗣 @Evgeny Shvarov, InterSystems Developer Ecosystem Manager

GlobalToJSON-Efficient

I have created a package that offers a utility to load a Global into JSON object and reverse
to create a Global from this type of JSON object. Efficient refers to the structure created.
Only Globals nodes containing data are presented in the generated JSON object.

This example demonstrates the difference you may experience when you write to
Gllobals directly from Embedded Python compared to native ObjectScript.

To make this demo useful I start 2 background jobs that simply write sequentially
to a dedicated global. A common control method signals for a synchronous start.
Similar a common stop & view interrupts data feeding.

That's the principle process:

Hey InterSystems Community!

This is probably far-fetched - is there a way to get notified/get a piece of code triggered whenever the state of a global changes?

Now what could I possibly want with that? Quite simple! I would like to forward the content of a global (in this case the "FSLog" global written by the FHIR implementation) while adding timestamps to it - to create some sort of file-based logging for it.

Maximum Global Size ?

Dear people,

I (really) spent hours on finding the maximum size a Global is allowed to be (for Windows, if that matters). All I seem to run into are database sizes (derived from a max number of blocks and block size), but I refuse to believe that is correct because too small to be realistic. surprise

Let's consider you would like to efficiently store your historical data in a similar structure than the one used for your current data, but without sharing the same physical storage (ie : not in the same global). What is the most efficient way to do it ?

Below a simple class of your current data :

Hi developers!

As you probably noticed in IRIS 2021 the names of globals are random.

And if you create IRIS classes with DDL and want to be sure what global was created you probably would want to provide a name.

And indeed you can do it.

Use WITH %CLASSPARAMETER DEFAULTGLOBAL='^GLobalName' in CREATE Table to make it work. Documentation. See the example below:

Hey developers!

Sometimes we need to insert or refer to the data of classes directly in globals.

And maybe a lot of you expect that data structure of global with records is:

^Sample.Person(Id)=$listbuild("",col1,col2,...,coln).

And this article is a heads up, that this is not always true, don't expect it as granted!

GlobalToJSON-embeddedPython-pure

I have created a package to export a Global into JSON object file and to re-create it by reloading from this file
embeddedPython refers to the new available technologies. It should be understood as a learning exercise of
how to handle the language interfaces. Only Global nodes containing data are presented in the generated JSON file.
Differently from the previous example, this one is using embedded Python only, no ObjectScript. Therefore PURE

GlobalToJSON-Academic

I have created a package that offers a utility to load a Global into JSON object and reverse
to create a Global from this type of JSON object. Academic refers to the structure created.
Each logical node of the Global is presented separately with all its descendants.
Even if they don't contain any stored data.

For some years I missed being able to offer, to everybody interested in ObjectScript, a tutorial more or less complete, to start with ObjectScript. Something that could help more and make things easier to those new developers that come to our technology... something intermediate, halfway between the common "Hello World!", that doesn't really get you further, and the "Advanced Training", that is unaffordable because of lack of time,etc.

If there were something truly helpful not only as an introduction to the ecosystem, but as a starting point, as a boost, to really start to walk into ObjectScript and move forward by yourself... wouldn't that be awesome?

Holiday Reading: What Lies Beneath!

For those of you who might be new to IRIS, and even those who have used Cache or IRIS for some time but want to explore beyond its usually-assumed boundaries and practices, you might want to dive into this detailed exploration of the database engine that is at its heart, and discover just what you can really do with it, going way beyond what InterSystems have done with it for you.

How to find a global's original namespace ? Potentially mapped from a different namespace .

I have a global ^Custom that exists in multiple namespaces but it could mapped from namespace Drone(A) to Launch(B)

Without access to Cache management portal how to find where is my global located using cache code ?

Like if ^Custom == ^[Drone]Custom ??

Hello community!

I'm facing a base growth issue, which is being generated by a process and an Ensemble feature.

When executing the process of cleaning up the message queues, the Ensemble “preserves” the Streams that were part of these messages, deleting only the Header and Body. In this way the database (of one of the namespaces) has grown around 60GB per day, which has been maxing out the disk capacity.

InterSystems informed that this is a characteristic and that it is explained in the documents mentioned below.

Making a blog using Python + IRIS Globals

Since I started to use internet (late 90's), I always had a CMS (content management system) present to make easier post
any information in a blog, social media or even an enterprise page. And later years putting all my code into github I
used to document it on a markdown file. Observing how easy could be persisting data into Intersystems IRIS with the
Native API I decided to make this application and force myself to forget a little of SQL and stay open to key-value database
model.

Hi Developers!

Here're the technology bonuses for the InterSystems Multi-Model Contest that will give you extra points in the voting:

  • InterSystems Globals (key-value)
  • InterSystems SQL
  • InterSystems Objects
  • Your data model
  • ZPM Package deployment
  • Docker container usage

See the details below.<--break->

Hi developers!

Often we need to deploy some data along with code pieces of the application.

And for InterSystems IRIS developers the question could sound: "How can I deploy the data I have in globals?"

InterSystems IRIS Globals Model QuickStart | InterSystems

Here I want to suggest to you one of the approaches - deploying global data using the ZPM package manager.

Hi, we suddenly noticed that one of the edge storage increased by 30% and it was due to ERROR globals which was throwing repeated error for 7 days and it consumed 35GB space. Is there a way to log the storage of edge production on daily basis and compare the increase in storage with previous day and if increase is 5% more than trigger an email to system admit to look why the storage increased suddenly.
