The best book that considers unit/functional testing in Zope 3 environemnt
is:

Hello,

I'm planning to develop a zope 3 web application. Before this, I would
like to read a book about unit testing and test driven development.
Does anyone know a good book about testing that will apply well to
python and zope?

Thanks!

It's even worser (due to a calculation error): 10 billion would mean 310 
tx/second but 100 billion would mean 3100 tx/second...you should look for 
something _bigger_.

[Zope3-Users] Is Zope Zope2 or Zope3?

[Alen Stanisic]

I received a February issue of Linux Journal and there it was, a review
of Ruby On Rails and Zope. Which Zope? I have a pretty good idea and it
didn't take *me* long to realise this was an article on Zope2.  I also
understand that a reference to Zope means Zope2 but to someone outside
of Zope world, they wouldn't have a clue.  If someone was looking to
evaluate a new framework after reading this and even after hearing about
Zope3 they will probably check out an alternative thinking the article
was also of relevance to Zope3.

There were also occasions when I mentioned Zope3 to people and them
telling me they "looked at it", in other words they looked at using
Zope2, decided not to use it and they are not likely to check it out
again.  I think this is the story of many in the python community, while
most of them know about Zope and many use Zope2, there are many that
decided not to.  The two *different* frameworks sharing the same name
might not help in getting these people to (again?) evaluate Zope3.  I
think Zope3 has great potential and should look to a lot larger
audience, not just Zope community, but python community and even outside
python community.  Not sure how many Ruby programmers there are but I
imagine not many which only means people are learning Ruby programming
language to get into Rails.  

I am just concerned that the name might slow deserved adoption of Zope3
outside of Zope community and this confused publicity in the press might
not help either.

[Zope3-Users] Re: Zope3-users Digest, Vol 15, Issue 31

[Paul Dumais]

I noticied that the installation documentation does not explicitly
explain how to install SchooBell within an existing Zope3 installation
(though it says this is possible).

Could someone give a brief overview of how this is done? Would I be
better off contacting the SchoolBell developers?

Thanks,

Paul

Well, if those transactions just add to a log, ZODB could handle it on 
suitable hardware.  ZODB could also handle it if there's no concurrency. 
 But you probably have concurrency and you're probably building indexes 
at the same time.  An RDBMS is just easier for that kind of task.

We're looking at 10-100 billion tx per year stored and performed.

Partly I'm trying to gauge where the dividing line is between using the ZODB
and not, and also estimate how many server instances should be running.

the ZODB because of it's versioning information in particular.



We have various datasets:

1.  Transactions: 10-100 billion objects


per day, month, yr?


2.  Users: 10-100 million objects


up to 1-2 million objects seem to be common for large sites nowadays


3.  Contacts: 100,000 objects
4.  Customers: 100-1000 objects


Possibly you might consider a hybrid solution using the ZODB and a RDBMS.

A quick note: In the things you mention, Zope 2 and Zope 3 are
similar, as they both use the same ZODB. So answers to your question
could equally be done with Zope 2 example. And I personally do not
have a high volume site, but such sites has been installed. The people
who did that gets to answer on how big they were. :)

The bottleneck with ZODB tends to be writing transactions, while just
reading transactions is handled with much greater ease, so that's the
most critical data in tis type of evaluations, I would guess.

[Zope3-Users] Zope 3 Capacities

[David Johnson]

I’m trying to scope out Zope 3’s
capacities.  Does anyone have a large ZODB? How big is it (in terms of
objects)?  Any performance issues?   Does anyone have a very
high volume site?  What kind of volume with what kind of degree of
application logic?  

 

What architectural things have affected performance?   I
general we’re looking at using an RDBMS, but we’re trying to get a
better feeling of when we can use the ZODB and when we should stick to the
RDBMS. I like the ZODB because of it’s versioning information in
particular.  

 

We have various datasets:


 Transactions: 10-100 billion objects
 Users: 10-100 million objects
 Contacts: 100,000 objects
 Customers: 100-1000 objects
