MIRROR for Embedded Python ?

MIRROR is the best solution for almost immediate replications to a Failover Server.
The related mechanics are based on Global Journaling.

Globals hold Data and Classes and Routines and more ...
If Mirroring is in place all is in sync. With minimum delays
This is of course rather useful for code changes in Classes, Routines, ....

To what extent is Embedded Python covered by Mirroring?
Or:
What is required to Synchronize EmbeddedPython like Mirroring.

embedded Python over ECP

With ECP we have the option to have a collection of Frontend instances
All Frontend servers typically have a common Master in the background
Concentrating data on the Master server is the primary goal.

As a side effect, this applies also to Classes, Routines, .. anything stored in Globals.
This is probably not the most efficient setup. But rather common anyhow.

Is embedded Python code also stored in Globals?

What is the recommended solution for a similar installation?

Reviews on Open Exchange - #34

If one of your packages on OEX receives a review you get notified by OEX only of YOUR own package.
The rating reflects the experience of the reviewer with the status found at the time of review.
It is kind of a snapshot and might have changed meanwhile.
Reviews by other members of the community are marked by * in the last column.

I also placed a bunch of Pull Requests on GitHub when I found a problem I could fix.
Some were accepted and merged, and some were just ignored.
So if you did a major change and expect a changed review just let me know.

Create JSON Objects and Arrays by SQL

The related package avoids adding %JSONAdaptor to each class but uses instead
SQL functions JSON_OBJECT() to create my JSON objects. With this approach, you can
add JSON to any class - even deployed ones - without any need for change or recompiling.

The trigger was the Export of M:N relationships as JSON objects or arrays.

I've been running my review collections on OpenExchange now for more than 3 years.
I explained the principle I apply in a past article.
These reviews are the first step of the quality check in OEX.

My personal Credo
My expectation of OEX (expressed in extreme) is to see it rather as
a collection of jewels, than just a flea market.

For my Embedded Python ONLY demo package I need some user input.
Similar to ObjectScript

read "say somthing",reply

I use the Python equivalent

reply = input("say something")

And this works excellent without problems from Terminal or Doker console

BAD SURPRISE:
with WebTermnial ObjectSscript works fine, but embedded Python fails badly.

As noted in the previous article Native API has some limits.
So I did some research on a more Terminal-like interface that
provides me with access like a console or the IRIS terminal
to allow my $QUERY over a global and other nice commands
that are not supported/mapped in NativeAPI for ObjectScript.

The basic tools are well-prepared and available.

Character-Slice Index

A recent question from @Vivian Lee reminded me of a rather ancient example.
It was the time when DeepSee's first version was released.
We got Bitmap Index.
And we got BitSlice Index: mapping a numeric value by its binary parts.
So my idea: Why not indexing strings by their characters?
The result of this idea was presented first in June 2008.
IKnow wasn't publicly available at that time.

OEX mapping #2

Technology Strategy

When I started this project I had set myself limits:
Though there is a wide range of almost ready-to-use modules in various languages
and though IRIS has excellent facilities and interfaces to make use of them
I decided to solve the challenge "totally internal" just with embedded Python, SQL, ObjectScript
Neither Java, nor Nodes, nor Angular, PEX, ... you name it.
The combination of embedded Python and SQL is preferred. ObjectScript is just my last chance.
