Developing an AI-Powered Observability Layer for IRIS Globals

Global Guard AI

1 Introduction

In environments that use InterSystems IRIS, globals are the physical foundation of data storage. Although system queries and administrative tools exist for metric inspection, global growth analysis is usually reactive: the problem is generally only noticed when there is disk pressure or performance impact.

Global Guard AI was developed to create a snapshot-oriented observability layer, aligned with the idea published in DPI-I-512 — and based on the series of articles written by Ariel Glikman, Sales Engineer at InterSystems:

Data Repoint NULLS Data In New Class Table When Old Class Property Is Changed & Saved

We are attempting to "Repoint" old class data to new class data to save disk space and data redundancy across multiple tables. This works to a point.  In essence the two classes are sharing the same data / Index / stream globals.  But if an ID in the Old_Class is opened, a property is modified, and saved the property that is in the New_Class (but not in the Old_Class) is NULLed / blanked.

Simplified explanation of data and what’s occurring.
