Has anyone tried to tackle this Million Record Challenge? It will be a good exercise for someone with time on his hands or for the ZK developers to show off their product.

Hi everybody!
Even I think this competition isn't really fair I found it interesting enough to spend some with it. I just make use of a paging listbox with four columns. The implementation is simple and stupid as I did no special optimization. To be honest: 1.000.000 seem impossible with this approach. I just tested up to 50.000 successfully. May an ItemRender will speed up loading? I have no idea... Maybe one of the ZK gurus can show how to speed it up! ;-)
And by the way: The Flex example is really impressive!

Hello Henri,
yes thanks for that hint. My naive expectation was that when I usesdfgsfg
a listbox with mold="paging" and a model object of ListModel* or whatever
(here ListModelList) dfgthat zk does this automaticaly.
When working with a sql database it makes sense to control the paging
by program as this can be linked to SELECT phrase "limit row_Start to row_end"
but when using a list of POJOs it would be great if zk can do this for us.
kind regards
Horst

henri's solution is not germane. you have to be able to load and sort and display the records in a short time, with, of course, no need to display all the records at the same time.

Hello zkfan!
Yes and no, zk has a server centric approach. So solutions need to be different, and for zk you have to implement sorting etc and some kind of paging. When I try to load a really large number of records while I try to keep my records in memory I get some out of memory exceptions even if I assign the jvm plenty of mem (about 2GB). Further, my FF collects memory like hell. The Flex speed is really impressive. Nevertheless zk has advantages when the data is read from databases and with databinding it is really great.
So I don't really thing that the approaches are comparable, but
First: paging as described in the mentioned smalltalk needs to much coding if the data is stored in a list of pojos. That should work automatically.
Second: Why do I need the paging mold. The scrollbar events are sufficient to calculate the visible part in a list box. Sorting of a pojo list requires almost nothing if the getters return values are of type string, int, float etc. So the browser just needs to hold the visible part and the Listbox would delive a server centric solution which is comparable to the Flex solution.
May I find some time to implement this - christmass is coming soon :-)

Hi everybody!
Even I think this competition isn't really fair I found it interesting enough to spend some with it. I just make use of a paging listbox with four columns. The implementation is simple and stupid as I did no special optimization. To be honest: 1.000.000 seem impossible with this approach. I just tested up to 50.000 successfully. May an ItemRender will speed up loading? I have no idea... Maybe one of the ZK gurus can show how to speed it up! ;-)

Hi everybody!
Even I think this competition isn't really fair I found it interesting enough to spend some with it. I just make use of a paging listbox with four columns. The implementation is simple and stupid as I did no special optimization. Toasdfsdfssdfsdf
And by the way: The Flex exadfdfsdsdfmple is really impressive!

Maybe someone is interested to improve my quickshot:
