ObjectScript extension for VS Code reaches 1.0

Hello Developer Community!

Once again I'm here to talk about the ObjectScript extension for Visual Studio Code, and this time we are excited to announce the release of version 1.0!

The community has come together in an unprecedented way to deliver this product with InterSystems, and its only fitting that a tool so critical to developer productivity would be built with community testing, feedback and source code from the very beginning.

As we all well know, InterSystems IRIS has an extensive range of tools for improving the scalability of application systems. In particular, much has been done to facilitate the parallel processing of data, including the use of parallelism in SQL query processing and the most attention-grabbing feature of IRIS: sharding. However, many mature developments that started back in Caché and have been carried over into IRIS actively use the multi-model features of this DBMS, which are understood as allowing the coexistence of different data models within a single database. For example, the HIS qMS database contains both semantic relational (electronic medical records) as well as traditional relational (interaction with PACS) and hierarchical data models (laboratory data and integration with other systems). Most of the listed models are implemented using SP.ARM's qWORD tool (a mini-DBMS that is based on direct access to globals). Therefore, unfortunately, it is not possible to use the new capabilities of parallel query processing for scaling, since these queries do not use IRIS SQL access.

Meanwhile, as the size of the database grows, most of the problems inherent to large relational databases become right for non-relational ones. So, this is a major reason why we are interested in parallel data processing as one of the tools that can be used for scaling.

In this article, I would like to discuss those aspects of parallel data processing that I have been dealing with over the years when solving tasks that are rarely mentioned in discussions of Big Data. I am going to be focusing on the technological transformation of databases, or, rather, technologies for transforming databases.

IRIS Download issue.

Hello there community,

As I am interested in taking part in the Full Stack Development for IRIS, I tried to download the Software and get hands on experience with it.

The registration went well, but unfortunately I only got a mail with regard to the download but the Software did not get downloaded.

I need the help of you experts please.

Am I doing something wrong or did I just miss some thing or some steps in between these that needs to be fulfilled?

I have a file passthrough service that should check for new new files every 10 minutes, process them and then wait again for 10 minutes, even if there are new files waiting in the source directory. The "CallInterval" value feels like a wrong tool for this need since it would keep the service "locked" for a maximun of 10 minutes before releasin resources. Is there a better way than CallInterval to schedule the service to poll for files every 10 minutes?

Hi All,

I'm being asked if I can set up a AWS EC2 containerised version of IRIS and a separate AWS EC2 installation of Apache to serve IRIS web files.

Creating the Apache EC2 and containerised IRIS EC2 is the simple bit but getting them both to talk to each other does not seem quite so simple and I cannot find any documentation to describe how this can be achieved.

Has anyone else managed to achieve this?
