According to Databricks Apache Parquet is an open source, column-oriented data file format designed for efficient data storage and retrieval. It provides efficient data compression and encoding schemes with enhanced performance to handle complex data in bulk. Apache Parquet is designed to be a common interchange format for both batch and interactive workloads. It is similar to other columnar-storage file formats available in Hadoop, namely RCFile and ORC.

Recently, the question came up while discussing the access to the data stored in IRIS from different languages with my students if it was possible to initiate the connection and get data from Cloud solution (InterSystems IRIS CloudSQL) from Microsoft Excel, not the other way around. Considering the many varied ways one can get data in Excel (import data from external sources, connecting to databases using ODBC drivers, using power queries and web queries etc.) the obvious choice was to try ODBC driver. The only task left was to try to connect to the database in the cloud using the ODBC driver.

Interacting with Users in the Terminal: A Guide to Using %Library.Prompt in IRIS

Have you ever wondered how commands like ^DATABASE engage users in the terminal? Or perhaps you're writing an automation routine and want ways to specify options directly from the terminal. Thankfully, the %Library.Prompt class in IRIS offers a straightforward way to do so!

Method or Class Method?

For programmers new to ObjectScript, one question will inevitably arise: “What is the difference between methods and class methods?” A typical answer would be: “A class method applies to a class, but a method applies to an instance of that class.” While that answer is correct, it lacks important information on how these methods di

VIP in GCP

If you're running IRIS in a mirrored configuration for HA in GCP, the question of providing a Mirror VIP (Virtual IP) becomes relevant. Virtual IP offers a way for downstream systems to interact with IRIS using one IP address. Even when a failover happens, downstream systems can reconnect to the same IP address and continue working.

The main issue, when deploying to GCP, is that an IRIS VIP has a requirement of IRIS being essentially a network admin, per the docs.

To get HA, IRIS mirror members must be deployed to different availability zones in one subnet (which is possible in GCP as subnets always span the entire region). One of the solutions might be load balancers, but they, of course, cost extra, and you need to administrate them.

In this article, I would like to provide a way to configure a Mirror VIP without using Load Balancers suggested in most other GCP reference architectures.

Beginning with the release of InterSystems IRIS® data platform 2022.3, InterSystems corrected the license enforcement mechanism to include REST and SOAP requests. Due to this change, environments with non-core-based licenses that use REST or SOAP may experience greater license utilization after upgrading.

Introduction to Kubernetes

In this article, we will cover below topics:

  • What is Kubernetes?
  • Main Kubernetes (K8s) Components


What is Kubernetes?

Kubernetes is an open-source container orchestration framework developed by Google. In essence, it controls container speed and helps you manage applications consisting of multiple containers. Additionally, it allows you to operate them in different environments, e.g., physical machines, virtual machines, Cloud environments, or even hybrid deployment environments.

Hi,

The system I am working on processes large numbers of records. Inserts, updates and so forth. There are multiple processes that can potentially work on the same table at the same time.

It is an almost impossible task to try and time these processes to not run at the same time, due to volumes, SLAs, etc.

Every now and then there are a few locking issues, Not many considering the volumes. It is just a bit of a nuisance as we need to reprocess these records later.

For some time I have been planning to do some type of proof of concept with the Workflow functionality, which, like so many other functionalities present in IRIS, tends to go quite unnoticed by our clients (and for which I say mea culpa). That's why I decided a few days ago to develop an example of how to configure and exploit this functionality by connecting it with a user interface developed in Angular.

Is there a way to compare the content of two variables/ lists and if they share a common element/ value return 1?

Example the two below both have "Yellow":

Set y = "Red, Green, Orange, Yellow"

Set x = "Purple, Black, Yellow, Pink"

The lists I am working with have over 30 elements/values that vary so it is difficult to hard code it to say look for "Yellow".

I need to verify that certain .m files have been compiled and inserted into the VA mumps database. I need to do it on a schedule and thus I want to automate it. Because of the automation I'd prefer not to use the IRIS web app. So if there were a similar CLI version that would be great. I see there is something called /usr/bin/iris but this seems to be a maintenance tool, not a IRIS.DAT querying tool. I'd love to be wrong about that.

Please forgive my lack of proper nomenclature, clearly I'm a n00b.

By default, all files created inside a container are stored on a writable container layer. This means that:

  • The data doesn't persist when that container no longer exists, and it can be difficult to get the data out of the container if another process needs it.
  • A container's writable layer is tightly coupled to the host machine where the container is running. You can't easily move the data somewhere else.

I am trying to setup a OAuth2.0 configuration to connect to a server within our Network using OAuth2.0. My previous attempt worked, however forgot to capture the steps before I had whipped the System so please bear with me.

I have an SSL/TLS Client configuration setup as we use the setup for our LDAP configuration.

When I go through the following steps within the Terminal, I am getting the following error...

The ideal number of table permissions to assign for your users is zero. Permissions should be granted upon sign-in based on the application used for access. For web applications, we have a simple way of doing this by appointing application roles, matching roles, and required resources in the System Management Portal.

ODBC and JDBC connections present a different problem, however, especially when third-party applications are involved. As providers of an ERP system, our customers often wish to be able to employ various software packages to integrate with or report on their data. Many of these programs are capable of running any kind of query. Yet, letting them do that can be devastating to a customer’s data.

VSCode New Files

The company I work for have a repository for one of our products which already contains both InterSystems and non-InterSystems source code. I'm in the process of trying to migrate us over to using VSCode to edit the InterSystems source but am stuck on some issues surrounding the files on disk and the routines in the IRIS instance.
