BTW, according to my personal experience flash player unable to handle
more that 10K records in data grid.
Just physically unable - out of memory error!
I have no problem populating a DataGrid with one million records. The
following program takes 519 MB when I run it on my Windows machine,
which has 2 GB of RAM. With no records it takes 73 MB, so each record
requires about 450 bytes of memory for the 6 String fields.

Hi all,
We've built a flex grid that supports mass action on its data right
now (column-wise search replace). But it just doesn't scale right
now. It can hold up to around 3K+ rows in the grid, but it's taking a
good few mins to load that up from the java backend servlet. The
requirement is for the grid to be able to support up to 100K+ or even
1 million rows (may be not displaying them all at once, but when the
mass action/search is taken, it should be performed on the complete
dataset, not just what is being served up on the grid).
We're just looking for ideas how this could be achieved, i.e.: if
pagination is needed, what is the best way to do? client side
pagination v.s. server? Could this be a good use case for Flex Data
Service? etc.
Any pointers/ideas/experience would be greatly appreicated. Thanks in
advance.
Regards,
Ban
