Hi. I have this situation. I'm creating a program for someone where
their customer's will be billed based on the amount of instances
(sessions) in a log file. There will eventually be hundreds or
thousands of customers with each one using up to hundreds of
sessions. There will be a line in the log file for each session used
for each customer. Figuring the test file I'm using is 4,000 lines
long and 400 Kb, 2,000 customers using 200 sessions each will result
in <gasp>400,000 lines</gasp>. Extrapolating, that gives me a 50 MB
file.
Now, this is probably extreme, but you never know.
What I want to do is show about 50 - 100 customers per page and have
it go through the cffile variable and count the lines for each file.
Then of course, I'll have to click Next to bring up the next group of
customers.
Reading this 400 Kb file seems to happen pretty well instantaneously.
But when it gets very large, I'd rather not read the file every
single time. I don't want to store a HUGE variable in the client
variable database and I've sworn off session variables.
My question: Do you think the performance hit will be worse reading
the file at every page load, or passing the variable from page to
page after initially reading it. And it is even POSSIBLE to pass a
HUGE variable with a form. And if so, what would be the best way?
Write a query and store it in a structure or array and pass that? If
I do it that way, I could just pass the customer ID and the number of
sessions used (rather than a record for each session used).
Suggestions? Ideas? :)
