I'm not sure what the purpose of this is, but the Management Console causes the browser to refresh periodically. If you're in a form or an editor such as the DTL or Routing Rule editors, you may lose work unless you save frequently. This did not occur in Caché 2018 and earlier releases.

I've had a couple of incidents where I've created a number of rules in the DTL editor, answered the phone or stepped away for a few minutes, then come back to find any work since the last save erased.

I've noticed this in both 2019 and 2020 releases of IRIS.

Heads up!

I'm looking into finding ways to  fetch data from cache efficiently and work with it with python - specially pandas.

i tried the following but i'm wondering if this is the most efficient way?

to run the stored procedure as %ResultSet inside cache in a classmethod and serialize the data to JSON

and then call that class method from python

Hi,

we're planning some work on our SQL Query Plan functionality for a future release of InterSystems IRIS and are interested to hear how you're using them today, or what'd keep you from using them. Rather than try and fit everything in a rigid survey, I thought a simple thread on our beloved DC might also reveal some use patterns that we support or could do a better job on.

Hi All,

We have few queries which are simple selects . For simplicity let's say there is a query that joins two tables and gets few columns and both tables have no indexes.

Select Tab1.Field1, Tab2.Field2
From Table1 Tab1
Join Table2 Tab2
On Tab2.FK = Tab1.PK

When we do query plan for this it shows approx 6 million,  however if we make a simple adjustment to the query

This is a lesson learned, which I would like to share with community.  


Recently I ran into an issue, where I was using %ConstructClone and it kept cloning extra records, which were not needed.  The record for which I was trying to run a clone had many-to-one relationships.  

The solution to this issue was using param -1.  If you run %ConstructClone(-1) it will not clone relationships, but rather just clone single oref as desired in this case.


I hope this information helps someone who is working with similar records.
