For background, I've developed code that relies on %JSON.Adaptor functionality across an entire package of classes in our codebase. In regenerating these classes with %JSON.Adaptor as a superclass, I've encountered compilation errors from the JSON adaptor generators in certain classes, triggered by certain property types or parameters that are incompatible.

Hi everyone,

I'm dealing with a situation where LOAD DATA operations — especially large batches with data inconsistencies — are consuming a lot of disk space. I've noticed that the same error messages are being repeatedly logged in the %SQL_Diag.Result and %SQL_Diag.Message tables, which is significantly increasing the size of the database.

One idea was to move these diagnostic tables to a separate database with a configured size limit, but before going down that path, I'd like to ask:

⏯️ Auto-scaling made easy in GKE with InterSystems Kubernetes Operator (IKO)

Kubernetes horizontal pod auto-scaling (HPA) is the key to handle the unpredictable compute workload in healthcare systems. IKO helps orchestrating the IRIS container deployment in Kubernetes including the capability to configure HPA. This demo uses XSLT processing as an example to showcase this type of elasticity.

Hi everyone,

I’ve set up a scheduled task in InterSystems IRIS to run every night at 2:00 AM, but it doesn’t seem to trigger consistently. Some nights it works as expected, but other times it just skips without any error in the logs.

The task is marked as enabled, and there are no conflicts in the Task Manager. I’ve double-checked the system time and time zone settings all looks fine.

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 This stream needs to be kept intact for historical reference so cannot be cleared between reads.

Dear Fellow Cache Gurus: I would like to know if there is either any built-in Cache Date/Time function or an easy way to include a timezone abbreviation such as EST, PST, MST, etc... within the Cache Date/Time formats.

I read through the Cache Documentation but could not find anything to achieve this.

So if I do the following command: $ZDateTime($H,1,4,,,4,,,,,"InvalidDate"), then I get an output like this: 02/27/2025 11:10AM

But I am looking for the output to be formatted like this: 02/27/2025 11:10AM EST

SQL Table - Data Cleanup

Hi Community,

I've created a method in my File Service to do a cleanup for every file load. Currently, I've set it to delete data when LastUpdated date is greater than maxdate. However, I want to do a cleanup for every new file load. Any suggestions or advice on how to do this? Thanks!

To manage the accumulation of production data, InterSystems IRIS enables users to manage the database size by periodically purging the data. This purge can apply to messages, logs, business processes, and managed alerts.

Please check the documentation for more details on the settings of the purge task:

⏯️ Autonomous Business Intelligent Clerk (ABiC) - Combining InterSystems BI and Generative AI

Our Autonomous Business Intelligent Clerk, or ABiC for short, is a prototype revolutionizing how companies process data and make decisions. Normally, to get insights from data, you’d need IT knowledge or expertise in statistics. But with ABiC, that’s no longer necessary. All you have to do is ask your question in plain language. ABiC understands your interests and intentions, then shows a clear dashboard to guide your decisions. With ABiC, complex data is autonomously analyzed and turned into answers that support users, helping to accelerate business processes. This demo sends the metadata of InterSystems BI cubes to LLM. How does it work? Check out the video for more details!
