I using ar\_extensions for mass insertions I found it very effective

all I want is to cache the inserted records into the variable when they  
are inserted

something of this kind for a single insert command

cached\_record = []  
records.each\_with\_index do |record,i|  
cached\_record \<\< Record.create(:name =\> record,:value =\> i)  
end

so that I don’t have to look up in database for the inserted records as  
I have them on the fly

is the above kind of code can used with ar\_extenions or any other  
options

so that when I do  
“Record.import()” for mass insertion of the records. The records can  
also be cache into a variable

same as above

Note : I don’t want to lookup in database as my database is huge  
crossing over five million records so looking up for the inserted  
records  
e.g  
cached\_record \<\< Record.all  
that a long amount of time close to 20 min

and I don’t need that

Thanks anyway

Perhaps you can save them to your cache before passing them into the  
import call? (sorry, don’t use ar\_extensions all that much).
