Easy data import into IRIS

Sometimes you need quickly and easily import data into IRIS. For this, an IRIS import manager has been developed.

This application allows you to import JSON data and also provides a really simple interface for transferring data from MongoDB collections to IRIS globals. It has never been so easy.

Let's look at examples.

Import JSON

Suppose we have data in JSON format and we want to import it into IRIS. To do this, you just need to specify the global name and insert the data. After import, you will see the imported data. If global exists data will be overwritten.

 

Import MongoDB collections

 

There is a collection navigation on the main page.

 

Just open the collection and you will see information about it and import control buttons that allow you to transfer data to IRIS or clear it.

After import, you will also see the imported data.

 

What other imports would you like to have in this application? Any ideas are very welcome.

IRS Docker micro Durability

Allow limited durability for demo and development IRIS-Docker-micro-Durability During development of a container based demo I found the need to access a fresh docker
an instance of IRIS image (e.g intersystems/iris-community:2020.2.0.199.0) over and over.
To bypass loading my code repeatedly I developed this workaround.

It is a reduced variant of Docker - light weight durability

Docker support

The principle of a persitent IRIS database outside the container is unchanged.
But now the whole setup is moved into Dockerfile and docker-compose.yml

Prerequisites

Make sure you have git and Docker desktop installed.

Installation

Clone/git pull the repo into any local directory

  git clone https://github.com/isc-at/IRIS-Docker-micro-Durability  

Open the terminal in this directory build and run the container:

  docker-compose up -d   

How to use it

Your container has now an external IRIS.DAT in </installdir>/demo/
It is setup as a working DB for Globals and Routines in namespace USER
REMEMBER: this is just for the content of this namespace
