First webinar on InterSystems API Management!


We are pleased to invite you to the upcoming webinar in Russian: Introduction to InterSystems API Management on November 21 at 10:00 Moscow time (GMT+3)!

As you might have heard, we recently introduced the InterSystems API Manager (IAM) - a new feature of the InterSystems IRIS Data Platform,
enabling you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure.

In this webinar I will highlight some of the many capabilities IAM allows you to leverage. InterSystems API Manager brings everything you need:

  • to monitor your HTTP-based API traffic and understand who is using your APIs; what are your most popular APIs and which could require a rework.
  • to control who is using your APIs and restrict usage in various ways. From simple access restrictions to throttling API traffic and fine-tuning request payloads, you have fine-grained control and can react quickly.
  • to protect your APIs with central security mechanisms like OAuth2.0 or Key Token Authentication.
  • to onboard third-party developers and provide them with a superb developer experience right from the start by providing a dedicated Developer Portal for their needs.
  • to scale your API demands and deliver low-latency responses

There would be a live demo.

This webinar is for System Architects, Developers and DevOps Engineers.
Time: November 21 at 10:00 Moscow time (GMT+3)!

The language of the webinar is Russian.

InterSystems API Management (IAM) - a new feature of the InterSystems IRIS Data Platform, enables you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure. In case you missed it, here is the link to the announcement. And here's an article explaining how to start working with IAM.

In this article, we would use InterSystems API Management to Load Balance an API.

In our case, we have 2 InterSystems IRIS instances with /api/atelier REST API that we want to publish for our clients.

There are many different reasons why we might want to do that, such as:

  • Load balancing to spread the workload across servers
  • Blue-green deployment: we have two servers, one "prod", other "dev" and we might want to switch between them
  • Canary deployment: we might publish the new version only on one server and move 1% of clients there
  • High availability configuration
  • etc.

Question
· Oct 12, 2019
How do you search with REST

The question is pretty much in title. I'm developing a REST API, it has a search endpoint with 10 optional parameters. How do I pass them and stay RESTFul?

To ease the question a bit let's agree that:

  • all parameters are AND parameters, user can't make combos, ORs, etc. User can only provide values
  • all values are integers so I don't have to think about URL limits
  • all values are atomic
  • all conditions are about equivalency

Some options I know of:

1. URL parameters.

Replacing character groups

What's the best way to replace character groups?

I want not to remove character groups as $zstrip does but to replace them with whitespaces.

$translate needs explicit character list.

Effectively I want to remove any characters besides letters, numbers and a small (known) subset of punctuation characters, replacing everything else with whitespaces.

Python Gateway 0.8 release

I'm happy to announce the latest Python Gateway release.

This is not an InterSystems product, it is community supported open source project.

Download new release from GitHub.

Now for the new features.

Fast transfer. Pass globals, classes and tables from InterSystems IRIS to Python with ease and speed (10x faster than old QueryExecute). Documentation.

Code Golf Index

Code golf is a type of recreational computer programming competition in which participants strive to achieve the shortest possible source code that implements a certain algorithm.

Here's a list of Code Golf competitions we had on Developers Community.

And some interesting challenges:

Is there a way to set null in dynamic object without using %Set methods?

I have this method and I need to set NULL as, well, null and not string.

ClassMethod node(name) [ CodeMode = expression ]
{
{
    "name":(name),
    "content":($case(##class(%Dictionary.ClassDefinition).%ExistsId(name), $$$YES:"mycontent", $$$NO:"NULL"))
}
}

I have two local instances:

  • IRIS for Windows (x86-64) 2018.1.2 (Build 626_3U) Wed Jun 12 2019 19:07:59 EDT
  • IRIS for Windows (x86-64) 2019.1 (Build 510U) Thu Mar 14 2019 14:13:37 EDT

I'm using Java Gateway to talk to external system.

Both instances are using the same:

  • jar
  • generated class
  • java version


They are calling the same method with this java signature:

CodeGolf: FizzBuzz

Let's have a round of CodeGolf!

As usual the goal is to write the shortest solution for a specified problem.

Today we have one of the classics: FizzBuzz.

Write a program that prints the numbers from 1 to 100.

But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”.

For numbers which are multiples of both three and five print “FizzBuzz”
