possible that the machine has multiple cores, so that multithreading can be used to process the entire dataset.
This article introduces solutions suitable for different application scenarios.
3. Solution
3.1 single-host + single-core + large enough memory
If each query word occupies an average of 8 bytes, the memory required for the 1 billion query words is about 10
() set 9 >>> s = set (a) 10 >>> s11 set ([0, 1, 2, 3, 6, 8, 9]) 12 >>> a = list (s) # remove duplicates and convert them to list13> a14 [0, 1, 2, 3, 6, 8, 9] 15 >>> s16 set ([0, 1, 2, 3, 6, 8
enough memory, then the data can be thrown directly into memory for one-time processing, or there may be multiple cores of the machine, so that the entire data set with multithreading.In this paper, we introduce a solution for different application scenarios.3.
