Re: No Preemptive processing on client

[Add Komoncharoensiri]

Hi All,

Indeed, currently the preemptive processing on 4D remote is not yet
available. It does not mean that it will not be there. The whole business
about making preemptive processing available everywhere in all areas
cannot be done in one shot, but rather in phases. The scope and priority
depends on where we see the heavy processing will be and you will most
benefit from it. In all cases, 4D Server had to be done first which most
likely will be running from the machine with the most number of cores (not
HT) anyway.

With our current Agile development model, you will continue to see the
evolution of the preemptive processing in 4D. Stay tuned:)

Regards,

Add

Pure speculation but it could be related to networking. How do you preempt code 
that is making calls to 4D Server over the network? I’m sure it’s possible but 
requires doing it the right way so that it actually works in any preemptive 
situation. I can see this becoming very complicated.

Maybe that was one of the reasons why they implemented the new network layer. 
To lay the foundation to all of this preemptive stuff. 

My guess it is temporary due to the complexity of the networking issues.

Re: No Preemptive processing on client

[Richard Wright]

Yeah, it’s of limited use if it’s only for stored procedures. I wonder if it 
has to do with the server twin process somehow. It would be good to hear from 
4D if this limitation will go away rather then wasting time rewriting code to 
run on the server if we don’t have to.

Re: No Preemptive processing on client

[Jeremy French]

How are we suppose to read the availability table (found in the section titled 
"Availability of preemptive mode")?


Does the table mean preemptive mode is available ONLY on server and single-user 
WHEN the database is compiled?

See:
http://doc.4d.com/4Dv15R5/4D/15-R5/Preemptive-4D-processes.300-2965368.en.html

Hopefully that's temporary, otherwise why bother?

I wonder why.

Here:

   
http://doc.4d.com/4Dv15R5/4D/15-R5/Preemptive-4D-processes.300-2965368.en.html

There is a section near the top called “Availability of preemptive mode”.
