Hi monks,

I am working on script wherein 1 million of records needs to be uploaded from the data base , say in every fifteen mins,and the with respect to the some input values in need to lookup in these records to get a value.

eg: hash key - 3456789,200805061200000
    hash value - 200805061200000,200905061200000,Group1

[download]

so in my script i will get the two key values as input and i need to do a lookup and fetch value information.

So I am confused about the best approach

1> I need to uploade these records to hash from database directly.

or

2>Keep a flat files with all these records and load hash with these data at the inital part of the script

or

3> directly read data from file

kindly help to me to select best option.

I am expecting a 2600 * 1500 input values in fifteen minutes and i have a memory of 64gb.
