Very nice article. Its exiting to see that Intersystems developers are taking advantage of the (great) Embedded Python feature in IRIS.

If you want to see a "real life" use case (we are using it for more than 2 years in our production environment), check this article: IRIS Embedded Python with Azure Service Bus (ASB) use case | InterSystems
(it also won the 1st place in an Intersystems article competition in 2022)
 

As you probably know, a stream is a "collection" of strings ("under the hood"). As the $ZCRC doesn't support incremental hashing you need to choose some other hashing that support this: SHA-256, MD5 (not recommended due to security vulnerabilities)

We will continue to use SAM for a while. Next year we plan to migrate to "DataDog" monitoring tool which is already being used in our company.
The /api/monitor/metrics/ can be still being used :-) 

I have tested the metrics rest/api and seems that the terminator that is being used is $C(10)

using the /LOGCMD is very useful to log the resulting command line into messages.log so you could have easy access to see from the SMP.

Also, I/O Redirection could be useful for having input, output, errors linked to files (both Linux and Windows)

Could you please give additional information on how the data is being pulled?
You say "tables" so I assume you run a SQL: Is this done by "select" or do you run a SP? 
Is this is a local task on the server (running a COS code) or externally with ODBC/JDBC connection?

I hope that the APIs (e.g. /api/monitor/metrics) will still work, so metrics can still be embeded into any monitoring tool that we are using like dataDog.

Is this correct to assume?

You may use $LISTFIND

$LISTFIND | InterSystems IRIS Data Platform 2023.2
 

For a-sync mirror membwers, you could use the query:

and then to iterate on result and do the necessary cheeks. 

Great workaround. I remember that I had a problem few years ago that the WebTerminal was unable to do:
ZLOAD routine ZPRINT
I did some (ugly, must say) changes in the broker to let this work
Does your wrapper is able to handle this as well? 

I would recommend that in systems that the audit database is big or huge you stop IRIS and move that database to another disk. Then change in IRIS.CPF (Database section) the location for the audit database. 

Check the user "task2" permissions, maybe this user does not have permission to the audit databse?

Which browser do you use? I noticed that in Edge the credentials box is not popped-up resulting an 401 error, so you need to work with "IE mode" (on chrome, it does pop-up).

I started programming around $H=55000.
Found in old MSM languange refrence manual ver. 4.4 that:

$ZU(1) and $ZU(0) are same as $ZUCI(1) and will returns the external name "UCI,VOL" for the current UCI   

I would check the following:

1. Check the %SYS.Task class with SQL but also do an Integrity check, to see if there are any errors on those globals that hold that task manager data.

2. if the "corrupted"/"copied" task (with $h=0) is the one that consume 100% of CPU, I would try to "re-schedule" it to see if the new "next date" is set to something else. If not, to delete (you don't need to re-create it, looks like 1001 is a copy of 1000)

3. Monitor the 100% CPU task (SMP or JOBEXAM) to try to understand at what commands it's "stuck" 

SQL adaptive mode s not avail. on 2022.1.2 but only on 2023.1 (right)

%SYS>s Status=##Class(Config.SQL).Get(.Properties)
%SYS>zw Properties
Properties("ANSIPrecedence")=1
Properties("AdaptiveMode")=1
... 
Properties("TimePrecision")=0

all headers are stored in the %request.CgiEnvs("HTTP"_xxxxx)

You may do something like this in the OnPreHTTP method in your CSP page:

if you encounter another situation that you cannot add a space before the # you can do:

Very good article, Yuri.

Wonder when Intersystems will support AMQP protocol, to integrate seamlessly with ASB (Azure Service Bus)

Hello,

If the database that you copy/import routines is journaled, and changes to routines source (^ROUTINE) and compiled code (^rOBJ) will also exist in the journal files. There is also a ^rBACKUP but it is not relay holding old versions of routines (for this you will have to use wither studio-hooks or GIT) 

90 min. to 1M records is very low.
It seems that the query is scanning at one of your big tables (Records maybe).
Do you have indices on: Records.qw and on Records.er
Consider to run the query in %parallel mode, after you optimize it.

Class codeGolf.Pyramid
{

ClassMethod Build(f As %Integer)
{
    F i=1:1:f K s,c S ($P(s," ",f-i+1),$P(c,"#",i*2))="" W s,c,!
}

}

Read this: CSP Session Management | Using Caché Server Pages (CSP) | Caché & Ensemble 2018.1.4 – 2018.1.7 (intersystems.com) - look at "Session Timeout" 

Yes the arbiter was unable to communicate. It looks like a network issue.
I recommend you to open a WRC for that 

Hello,

Basically, a namespace is a "logical" place that can have it's data from more than 1 database.

You have namespace1 binded to database1.
When you create a new namespace2 (binded to database2) and then create a "global mapping" for namespace2 to point for your specific globals from database1
