I have a file that contains records of customer interaction
The first column of the file is the batch number(INT) , and other columns
are date time , close time etc etc
I have to sort the entire file in order of the first column .. but the
problem is that the file is extremely huge.
For the largest customer it contains 1100 million records and the file is
44GB !
how can I sort this big a file
First, consider putting it in a database.
Split the file into little ones, sort them, merge-sort them back together.
