Hi fellow developers!

Curious if you guys use CreatedAt and LastUpdated properties in your classes?

Created to stamp when the record was created and LastUpdated when it was last updated. Where it can be useful - almost everywhere )) I find it convenient in records sorting (e.g. by creation or last update), in sync (with other systems), and so on, for better analytics.

Do you use it all the time for all the classes?

If don't, why not? What do you use instead?

What property type do you use - %TimeStamp? %DateTime?

What is the best practice to have CreatedAt filled automatically during creation and LastUpdated on every successful save (guess it could be in %OnSave)?

Please share your experience /thoughts?

Hello,

Is there a single ObjectScript operator or method to concatenate two %DynamicArrays?

I'm looking for something that will do the following:

set arr1 = [ 1, 2, 3 ]
set arr2 = [ 4, 5, 6 ]
set arrcombined = arr1.%Concatenate(arr2)

or

set arrcombined arr1_arr2

With end result:

zw arrcombined
arr1=[1,2,3,4,5,6]  ; <DYNAMIC ARRAY>

I can iterate and %Pop over the 2nd array and %Push each popped entry to the 1st array, but I was looking for something more succinct.

Thanks in advance.

RabbitMQ is a message broker that allows producers (those who send a data message) and consumers (those who receive a data message) to establish asynchronous, real-time, and high-performance massive data flows. RabbitMQ supports AMQP (Advanced Message Queuing Protocol), an open standard application layer protocol.
The main reasons to employ RabbitMQ include the following:

  • You can improve the performance of the applications using an asynchronous approach.
  • It lets you decouple and reduce dependencies between services, microservices, and applications with the help of a data message mediator, meaning that there is no need for producers and consumers of exchanged data to know each other.
  • It allows the long-running processing of sent data (with the results) to be delivered after utilizing a response queue.
  • It helps you migrate from monolithic to microservices, where microservices exchange data via Rabbit in a decoupled and asynchronous way.
  • It offers reliability and resilience by making it possible for messages to be stored and forwarded. A message can be delivered multiple times until it is processed.
  • Message queueing is the key to scaling your application. As the workload increases, you will only have to add more workers to handle the queues faster.
  • It works well with data streaming applications.
  • It is beneficial for IoT applications.
  • It is a must for Bots’ communication.

Hi ,

I am creating a report on Trakcare with the help of Jreport. But the date parameter from trakcare is not reading on Jreport and the report is blank.

If I hardcode the date on Jreport,it is displaying on Trakcare but not taking report from Trakcare.

Parameter used on report manager on Trakcare is $g(%request.Data("DateFrom",1)).

Can anyone please tell me any change of settings on Trakcare or Jreport will help to work ?

Thanks for the help

Jude

I have an operation using $ZF this operation ran and did not error but the job has been active and it can not be stopped I have tried stopping it from the front end and through the terminal using ##class(ENSLIB.Job).%New() Stop method. Now my production will not update even if I add a new item to the production I cannot update the item is there a way to force stop this job.

Over time, while I was working with Interoperability on the IRIS Data Platform, I developed rules for organizing a project code into packages and classes. That is what is called a Naming Convention, usually. In this topic, I want to organize and share these rules. I hope it can be helpful for somebody.

High Availability IAM

One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.

Minify XML in IRIS

In a project I'm working on we need to store some arbitrary XML in the database. This XML does not have any corresponding class in IRIS, we just need to store it as a string (it's relatively small and can fit in a string).
Since there are MANY (millions!) of records in the database I decided to reduce as much as possible the size without compressing. I know that some XML to be stored is indented, some not, it varies.

What are best practices for JSON transformation in IRIS interoperability? This is for a non-healthcare use case, so any tools we happen to have around FHIR might not be available. The motivating use case is trimming down a verbose and needlessly complex REST API response to feed to an LLM - trying to reduce token usage and maybe get better results from less noisy data.
