Plug-N-Play on Pattern Match WorkBench

Plug-N-Play on Pattern Match WorkBench

Article to announce pre-built pattern expressions are available from demo application.

AI deducing patterns require ten and more sample values to get warmed up.

The entry of a single value for a pattern has therefore been repurposed for retrieving pre-built patterns.

Example: Email address

Paste an sample value for example an email address in description and press "Pattern from Description".

About parallel queries (%PARALLEL)

InterSystems FAQ rubric

One way to optimize query performance is to use query parallelism on a per-query or system-wide basis (a standard feature).

This is a technique for dividing the execution of a particular query among processors on a multi-processor system. The query optimizer will execute parallel processing only if there is a possibility of benefiting from parallel processing. Parallel processing is only applicable to SELECT statements.

Hey Community,

Last week, the InterSystems team held our monthly Developer Meetup in a new venue for the first time ever! In the AWS Boston office location in the Seaport, over 71 attendees showed up to chat, network, and listen to talks from two amazing speakers. The event was a huge success; we had a packed house, tons of engagement and questions, and attendees lining up to chat with our speakers afterwards!

So I have been working in Healthcare Interops for about a month now and in IRIS. I am looking to implement SMART on FHIR and I am currently working to make an endpoint that works as the discovery endpoint. It is a custom dispatch class and unauthenticated is selected for access. I am trying to make a simple get request from Postman to test that the proper JSON is sent, but I receive a 403 Forbidden error. It is reaching IRIS it seems so I know its not a reverse proxy error. Here is an example of my custom Dispatch Class.

Hi Everyone!

We have an existing process (running in FIFO order), all business hosts having pool size=1.

Currently we are reading records from a file (one record at a time) then that record goes to business process for further processing and finally through the business operation. As of now we are using synchronous call in our existing code. Before processing the last record we are using hang of 50 seconds because we need to initiate a batch once the processing of last record is finished.

Hi developers!
Happy holidays!

In ObjectScript there is neat option to log errors - call Log() method of an exception intance, e.g.:

ClassMethod MyMethod() {

Try {

w 1/0

}

Catch e {

do e.Log() // logging error in the app log

write "the error happened: "_e.DisplayString()

}

}

Is there anything like that for Embedded Python? e.g:

ClassMethod MyMethod() [Language = python] {

 try:

   print(1/0)

 except ZeroDivisionError as e:

   // how can I log e into IRIS App Error Log here?

   print("Caught exception: " + str(e))

}

Any ideas?
