I have a stream that I read out until the end. I then append more content to the stream and want to read out only what has been added. How do I only read out the new contents of the stream? Essentially, I want to read a stream, record the end position, then once the stream is updated read the contents from that recorded position until at the new end. This stream needs to be kept intact for historical reference so cannot be cleared between reads.

Hello to all my fellow Cache Developers/Experts out there :)

The purpose of this post is to get input/feedback regarding an issue we are having with our Cache LIS web-based application not being able to remove locks that were taken under a separate process.

Here is the background of how the LIS does the locking and details about the issue:

For those that use IRIS for Health, HealthShare, and or Health Connect...

As Health Applications are moving to the Cloud, how have you handled communication from the Application to your instances via HTTPS?

Trying to figure out the best path on designing the proper workflow to allow these messages to be allowed to be eventually sent to our EMR to post to the patient chart.

We are very wary of opening a connection from the internet to our instance of Health Connect.

Thanks

IntegratedML

Hi Guys,

I'm a newbie that doesn't know much about integratedML and looking for a first push into it, I've setup VSCode with my IRIS 2024.3 running in Linux and my understanding is that we can create models using SQL, so first, do I need to setup a specific environment where I can run my SQL commands to create & train Models or just using SMP, and do I need to install or enable Python ..etc things required to setup the environment?

Then if there are easy samples or training materials on how to create, train & deploy my model?

Thanks

Another step in this implementation path, adding cross cloud, cross regional stretched IrisCluster with Mirroring + Disaster Recovery using the Intersystems Kubernetes Operator (IKO) and Tailscale

Though trivial, Id like to go multi-cloud with the stretched IrisCluster for a couple of reasons to socialize the power of Wireguard when it supplies the network for a properly zoned IrisCluster by adding another mirror role to Amazon Web Services in the Western United States based datacenter in Oregon.

Hello to all the Cache Experts out there and Happy Friday!

The company I work for uses Cache 2017.1.3 and we have been seeing intermittent errors in the Cache Error Trap when an SQL query runs. The error message looks like the error is occurring within the cached query routine that Cache auto-generates. Unfortunately, when I pulled up the routine in the SMP System Explorer, I only found an obj version, so was unable to look at any code.

Hello,

I'm trying to connect a Python backend application to an InterSystems IRIS Community Edition instance running in a Docker container on an AWS EC2 instance. I'm facing persistent connection issues and an SSL Error despite the Superserver apparently having SSL disabled. I'm hoping for some insight into what might be causing this contradictory behavior.

My Setup:

I'm running the image "containers.intersystems.com/intersystems/irishealth-community:2025.1" as a container on my local Docker desktop.

Now I want to set up an ODBC SQL connection, but I don't know how to do it.

I have tried various ways without success. Like building my own image (see "Dockerfile" description below).

I have also added ODBCINI variable in my docker-compse (see "Docker-compose.yml" description below).

Anyone done this before?

I'd really appreciate some help.

Thanks.

I am testing vectorsearch, while doing so I am trying to paginate my resultset for a "next page" function to give me the first, second, third 15 entries within a table.

For this I have two embedding classes. One with a HNSW Index (vectornomicembedtextlatest) , and one without (vectornomicembedtexttest).

Calling SELECT ID,PRIMKEY FROM SQLUser.vectornomicembedtexttest LIMIT 5 OFFSET 1 works fine with the first entry having the rowID of 486448. (I deleted old entries in the beginning and reused the table)
