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.

Generative AI for image creation

Currently, many digital artists use generative AI technology as a support to accelerate the delivery of their work. Nowadays it is possible to generate a corresponding image from a text sentence. There are several market solutions for this, including some available to be used through APIs. See some at this link: https://www.analyticsvidhya.com/blog/2023/08/ai-image-generators/.

modifity status RW database

Hi folks!

I need to change a status database to RW with the class

I used scripts for this, for example, I can create a database like this

setup_database() {
csession -B -U "%SYS" <<-EOF
zw ##class(SYS.Database).CreateDatabase("/InterSystems/cachedb/mydatabase")
set Properties("Directory")="/InterSystems/cachedb/mydatabase"
zw ##Class(Config.Databases).Create("MYDATABASE",.Properties)
halt
EOF

How can I modify this status R/W?

Reviews on Open Exchange - #36

If one of your packages on OEX receives a review you get notified by OEX only of YOUR own package.
The rating reflects the experience of the reviewer with the status found at the time of review.
It is kind of a snapshot and might have changed meanwhile.
Reviews by other members of the community are marked by * in the last column.

I also placed a bunch of Pull Requests on GitHub when I found a problem I could fix.
Some were accepted and merged, and some were just ignored.
So if you did a major change and expect a changed review just let me know.

New CACHE.DAT file

Hello,

I have a database drive which is getting full and almost getting out of space. My retention policy is for keeping 3 days worth of data. Seems like I have to modify my code for daily purge as it seems like not doing the complete job. In the meantime, I was looking to move the current CACHE.DAT files for a couple of my databases with maximum size and create a new .DAT file to replace. Can anyone kindly guide on the process?

Thank you,

While starting the development with IRIS we have a distribution kit or in case of Docker we are pulling the docker image and then often we need to initialize it and setup the development environment. We might need to create databases, namespaces, turn on/off some services, create resources. We often need to import code and data into IRIS instance and run some custom code to init the solution.

And there plenty of templates on Open Exchange where we suggest how to init REST, Interoperability, Analytics, Fullstack and many other templates with ObjectScript. What if we want to use only Python to setup the development environment for Embedded Python project with IRIS?

So, the recent release of Embedded Python template is the pure python boilerplate that could be a starting point for developers that build python projects with no need to use and learn ObjectScript. This article expresses how this template could be used to initialize IRIS. Here we go!

A framework yes, but a suitable framework

How can IRIS productions be deployed more quickly and with greater peace of mind?

The aim of interoperability productions is to enable you to connect systems in order to transform and route messages between them. To connect systems, you develop, configure, deploy and manage productions that integrate several software systems.

Hello,

First of all thanks for your time, thoughts, teaching and help:

We wonder how could we get the metrics from http://[Ip]:[Port]/api/monitor/metrics and use them in Kibana to chart statistics.

We would like to ask you how do you use the api monitor metrics, and as a second question, how would you suggest to utilize them in a third party software as Kibana to chart them.

We have thought to do the following:

I'm currently facing an issue with a Python script in my IRISHealth environment and would appreciate your insights.

I've written a class method, `getTokenCount`, in Python, which uses the `tiktoken` module. However, when I run the script in the terminal using `do ##class(python.openaiUtils).getTokenCount("")`, I encounter the following error:

Hello, I am quite new with InterSystems, SAM and Grafana. I am looking a way to get Log Files and Application Errors from InterSystems to SAM like in this post: https://community.intersystems.com/post/grafana-support-intersystems-iris. Is this plugin still under development or is there any other way to get those errors? By using SAM, I do not get those errors.

I'm working for an organisation that is running a very old version of InterSystems Cache (5.016) which runs on AIX . The last two times we have re-booted Cache, we have encountered rollbacks. I've been asked two questions. During the rollback it was "How long is it going to take?" and after the system returned, it was "So what caused it?". My answer to both was "I don't know".

Working with Named Pipes

While creating my latest examples for the JavaContest I faced the need
to communicate with my code from a program in IRIS to my Java code.

Communication with |CPIPE| worked as READ or WRITE but not both?
In the Documentation Named PIPEs are explained rather shortly.
"Once open, a pipe acts like an ordinary device." Not so precise.
I failed to achieve my expected READ/WRITE as TCP would offer.

NativeAPI for Java from WebTerminal

Based on the successful solution for my 2nd contribution to the Contest
I used an adapted version for this package. And have some findings I'd like to share.

Multiple communication steps over CPIPE may take time.
You won't recognize it on a fast machine. But a slower box with
Windows + Docker Desktop + your browser (and more) is neither
"Speedy Gonzales" nor a "Road Runner". 🙂

Good day,

We recently had penetration testing conducted on our HealthShare clinical viewer and patient Index instances and below is the recommendation

1. Set a same-site cookie for identified CSPWSERVERID. Please advise where I can do this as I only saw this on web gateway settings and it has enable and disable options only.

HL7 field for base64 in orl

Hi everyone,

It could be great if some of you have had experience in hl7 v2 messages. The question is about FHIR to hl7 v2.5 conversion. I have to translate a binary resource, encoded in base64 into an orl_o22 message. Do you have advices? Which field could be used for that datatype?
I have found some implementation using nte segment but it is limited in characters.

Thank you

Hello,

First of all thanks for your time reading this doubt.

We have discovered the following behaviour. Inside a Router we have a roule which needs to filter out the ADT_A08 messages which have not OBXs.

The legacy system had this rule implemented:

(((Document.{OBX(1).SetIDOBX}<"1")||((Document.{EVN:EventReasonCode}!="COD")&&(Document.{EVN:EventReasonCode}!="FIN")))

However we have tested it and it does not filter out the ADT_A08 messages.
