the business three. Library Table Hash Table hashing is similar to horizontal segmentation, but there is no obvious dividing boundary like horizontal segmentation, the hash algorithm is used to disperse the data into various tables, so IO is more balanced. In general, we will be in accordance with the business or functional modules to separate the database, different modules corresponding to different d
