A fio problem is found during work. The read speed of the data tested by the test group is 17.0 g/s, And the read speed is 13.2 g/s. You know, I only have 24 7.2 K RPM hard drives in the background! It is impossible to have such a speed. After I got home, I simulated the actual situation and the result showed the situation again: Run FIO-filename =/tmp/test-Direc

Label:scenario : Traverse and process all the data in a large table, the data in this table may be thousands or hundreds of billions of dollars, many people may say with paging limit ...

The code in the data is read and the result is executed. I used insert to insert the following data into the mysql database: for (int nbsp; I = 0; I lt; dst. length; I ++) { nbsp; system. out. after println (dst [I]); nbsp;} succeeds, I read the code in mysql nbs and the result is executed. I used insert to insert
