Columnar Storage in 2022.3

As you may well remember from Global Summit 2022 or the 2022.2 launch webinar, we're releasing an exciting new capability for including in your analytics solutions on InterSystems IRIS. Columnar Storage introduces an alternative way of storing your SQL table data that offers an order-of-magnitude speedup for analytical queries. First released as an experimental feature in 2022.2, the latest 2022.3 Developer Preview includes a bunch of updates we thought were worth a quick post here.

Date range queries going too slow for you? SQL Performance got you down? I have one weird trick that might just help you out! (SQL Developers hate this!)*

If you have a class that records timestamps when the data is added, then that data will be in sequence with your IDKEY values - that is, TimeStamp1 < TimeStamp2 if and only if ID1 < ID2 for all IDs and TimeStamp values in table - then you can use this knowledge to increase performance for queries against TimeStamp ranges. Consider the following table:

EN Interopway XDBC

Hey guys!!!

I finally got some time to organize a set of classes that I've been using for a few years to make it easier and kill the repetitive work of developing intragrations using XDBC.

Access the project repository at https://github.com/cristianojs/interopway

I've already registered on the Open Exchange. I'm wait for approval.

The idea is to increase the project with more components, I already have one that the "dough is rising and is already going to the oven".

Any questions post here.

Hi

Just looking to tighten up a new application

As an example, the application may have a path such as;

Omniata.au/csp/SomeApp/ListIndex.csp

on a Windows server in the path of ;

C:\InterSystems\IRIS\CSP\SomeApp

and display images from a path such as;

C:\InterSystems\IRIS\CSP\SomeApp\images\Pic1.jpg

If a user wishes to browse through the website, they could point their browser at the path ;

Omniata.au/csp/SomeApp/images

and guesses some file names, they could view the images

Yesterday I downloaded and attempted to install the newest version of the Community Edition of IRIS but not the preview, and attempted to update an older version, but each time I tried to install it, I would get an error, and then an antivirus program would indicate that it had identified and blocked a threat (McAfee identified it as GenericRXAA-FA!EAEEF9B8457F with a location of C:\Users\jivey\AppData\Local\Temp\pbt3FDD840C\IRIS_x64.msi). I tried the installation again this morning and this time a threat was identified by Malwarebytes as Malware.AI.4072586503 and McAfee identified it as i

Hi Friends ,

I have created inbound DB adapter business service. Now my requirement to trigger this service at 10am daily.

I used scheduler , but I don't know when should i configure for stop. this not suits for my requirement.

Is there any other way , where I need to trigger service only once , in configured times.

Thanks,

Prashanth

So, the next year will bring us a new way of installing IRIS. Always keep in mind that you have to bring your own web server. No matter how many instances of IRIS you have on your local machine. Or if you work in Docker, always keep in mind a bit more complicated configuration.

And I now want to understand the costs of this decision for end-developers like most of here.

Hello everybody,

In the documentation I read the following:

Alerts are messages generated by production components. InterSystems IRIS automatically writes the alerts to a log file and sends then to the production component named Ens.Alert. If your production does not have a component named Ens.Alert, then InterSystems IRIS writes alerts to the log file but does not send them to any component. The component named Ens.Alert can be of any class. The most frequently used classes for Ens.Alert are:

I have table

CREATE TABLE nodes (
        name VARCHAR(50) NOT NULL, 
        parent VARCHAR(50), 
        PRIMARY KEY (name), 
        FOREIGN KEY(parent) REFERENCES nodes (name) ON UPDATE cascade
);

I put some data

INSERT INTO nodes (name, parent) VALUES ('n1', NULL);
INSERT INTO nodes (name, parent) VALUES ('n11', 'n1');
INSERT INTO nodes (name, parent) VALUES ('n12', 'n1');
INSERT INTO nodes (name, parent) VALUES ('n13', 'n1');

Let's delete all

DELETE FROM nodes;

Nope, no way.

SQL Error [124] [S1000]: [SQLCODE: <-124>:<FOREIGN KEY constraint failed referential check upon DELETE of row in referenced table>]
[Location: <ServerLoop>]
[%msg: <At least 1 Row exists in table 'SQLUser.nodes' which references key 'NODESPKey2' - Foreign Key Constraint 'NODESFKey3', Field(s) 'parent' failed on referential action of NO ACTION>]
