Share volumes across pods and zones on EKS

Background

For a variety of reasons, users may wish to mount a persistent volume on two or more pods spanning multiple availability zones. One such use case is to make data stored outside of IRIS available to both mirror members in case of failover.

Unfortunately the built-in storage classes in most Kubernetes implementations (whether cloud or on-prem) do not provide this capability:

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.

I am hoping I explain this correctly.

We are using a query expire edge, to pass an API request to one of our vendor systems.

There is no feed into the gateway from an external system, and it is only used to query the external system with member data.

However, it is our understanding that the member needs to be registered on the edge.

Wondering if there is a way to export from the registry the bare demographic info in SDA to import to the new edge?

I'm new to Cache and trying to follow the Using Cache Studio PDF. In section 2.4.3(Adding a Zen form) it tells you insert the following code;

<button caption="Save" o select="zenPage.saveRecord();" />

Unfortunately that code fails compilation. If you try and use the tools there is no o select option nor a select or onselect option. I was wondering if anyone has used this PDF before and knows what the correct attribute should be?

Comprehensive patient view, communication and data sharing, and population health management are key components

Federal agencies have been incenting healthcare providers to leverage their electronic health records (EHRs) to get patients involved in the management of their care. Most organizations, however, haven’t moved beyond patient engagement as an item to be checked off in order to receive meaningful use incentive funding.

I implemented a Python Flask application for the 2024 Python Contest with a page that provides common form fields for an outgoing email such as the To and CC fields. And it lets you input a message as well as uploading text based attachments.

Then using LlamaIndex in Python, the app analyzes the content you put in and returns to you in a result box if there is anything that should stop you from sending that email.

Take a look at the Github repo here.

Hello everyone,

I just want to know if there is a difference in performance between using Class methods versus MAC routines?

For example:

do Method^MyFunction()

versus

do ##class(MyFunction).Method()

We have some custom tools that do project based deployment from environment to environment. In VS Code, we're struggling to find the best way to export PRJ files that contain the contents of a project the way we were able to in Studio. We can edit existing projects, and in server side editing we can create projects, but we can't seem to extract the project files (Not the classes, the wrapper) to store in our source control solution for deployment purposes.

debugging %Library.ResultSet

Hi All,

I am trying to fetch resultset using the below code -

set rs = ##class(%ResultSet).%New("Simple.Person:ValidateAge")

do rs.Execute()

it is giving me error while the same code I run it through iris terminal worked fine.
I want to understand that problem behind this. Also how can I check the possible methods that I can use on 'rs' somewhat dir() does in python.
