Optimized Method
Hi All,
I have got two files.
File A with 50000 records and
File B with some 500 million records.
I need to extract the mapping data (common data) from both the files.
There should be definitely many ways
though I have a way which is definitely not optimzed and takes a longer time to run.
What bothers me is the time taken to run?
Any optimized way to do that?
Cheers!
