Given a, b two files, each store 5 billion URLs, each URL occupies 64 bytes, memory limit is 4G, how to find a, b file common URL?You can estimate the size of each file as5g*64=300g, far greater than4G. So it is not possible to fully load it into memory for processing. Consider adopting a divide-and-conquer approach.Traversing filesA, for eachURL FetchHash (URL)%1000, and then, based on the resulting value,URLs are stored separately in the1000 Small f

Given the two files a and B, each of them stores 5 billion URLs. Each url occupies 64 bytes and the memory limit is 4 GB. How can we find the common URLs of files a and B ?, 5 billion 4g 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, ob
