It can be estimated that the size of each file is 5g * 64 = 300g, much larger than 4G. Therefore, it is impossible to fully load it into the memory for processing. Consider a divide-and-conquer approach.Traverse file a, obtain Hash (URL) % 1000 for each URL, and store the URL to 1000 small files (set to A0, A1 ,... a999. In this way, the size of each small file is about 300 MB. Traverse file B and store the URL to 1000 small
