Globals documentation

I have a client with cache instance that is growing by 10-30G/day. In order to determine what is consuming space I ran "DO ^%GSIZE" to generate a report. From the report the bulk of the space consumption is from a couple of globals which appear to be built in globals not user defined. I would like to find documentation that details the function of these globals to help me understand how and why space is being consumed at such a rapid pace.

IntegratedML walkthrough

The InterSystems IRIS IntegratedML feature is used to get predictions and probabilities using the AutoML technique. The AutoML is a Machine Learning technology used to select the better Machine Learning algorithm/model to predict status, numbers and general results based in the past data (data used to train the AutoML model). You don't need a Data Scientist, because the AutoML it will test the most common Machine Learning algorithms and select the better algorithm to you, based in the data features analysed. See more here, in this article.

VSCode: Formatter not found

Hi,

I am using VSCode together with IRIS 2021.1.
When using Shift+Alt+F to reformat a class file, it pops up with the below message. When I select install formatter, it routes me to the extensions page, where it shows the extensions as being installed. Any advice will be appreciated.

This article is a follow-up to the previous one on how to migrate from popular databases (like PostgreSQL and MySQL) to IRIS.
We will use the same procedures utilized to migrate from PostgreSQL. However, you will see that it is even easier since the data types in MySQL are very similar to IRIS. That is why we will not need to create transformation rules in the columns.

Get the sample data to the migration process

In GitHub it is possible to download a docker-compose project to build and run 2 databases:

In this article I will explain the usage of %SQL_Diag.Result and %SQL_Diag.Message table along with all-new LOAD DATA functionality.

It is recommended to go through LOAD DATA documentation first.

After successful operation LOAD DATA insert one record in %SQL_Diag.Result table and details are inserted in %SQL_Diag.Message table


Below is the basic command when table is already created and source file does not contain header row. 

LOAD DATA FROM FILE 'C://TEMP/mydata.txt' 
INTO MyTable

The file name must include a .txt or .csv (comma-separated values) suffix and both source and target have the same sequence of data columns.

Loading from File Source: Header

Calling Python Class Methods

Hi,

What is the Python syntax I can use from a ClassMethod (developed in an IRIS using embedded Python), in order to invoke another class method,

- in the same class; and

- in another class.

I see 'self' is synonymous to use $this (..) in ObjectScript, but these are ClassMethods I am invoking, and self did not seem to work.

thanks - Steve

Embedded SQL Bug and Workaround

We recently encountered an Embedded SQL issue while upgrading to IRIS 2021.1, and thought the issue and workaround might be interesting to share.

Key takeaway: Host variables in an ORDER BY clause of an embedded SQL query that is inside of a method don't work as expected. IRIS versions starting with 2020.1 are affected. As a workaround, add the host variable to the Method's PublicList list and "new" them so the embedded query has access to them.

It's come to our attention that the built-in license in the InterSystems IRIS and IRIS for Health 2021.1 Community Edition release is incorrectly set to expire on October 30, 2021.

There is no impact to any production versions (the Community Edition is for development purposes), but developers will find that their instances stop running and should replace them with new ones. For cases where replacing them is an issue, we have provided an override key.
