Then write the name of the generated xml file, the minimum id of the retrieved question, the maximum id of the retrieved question, and the number of retrieved questions into a txt file for index query. The format is roughly like this. 0,3146886,3145887,1000 Did you find that the last number is 1000? The first time you select, take out 1000 pieces of data, and then write it into the 0.xml file. Write the extracted xml file name, minimum id, maximum id, and number of entries into the index query txt. For the first time, 1,000 pieces of data were written to 0.xml, and the number of pieces generated was 1,000. The select statement will become when querying for the second time. where id > The maximum id taken out (currently mysql is a forward order query, if it is in reverse order, change it to less than) limit 1000 In this case, take out 1000, and then modify the minimum id and maximum id of the index query txt, and add the number of generated items to 2000 . By analogy, when the number of generated items reaches 5000, start another line and write it into the index file, similar to this 0,3146886,3145887,5000 1,3148886,3147887,1000 If you write it like this, it will reduce the problem. reduces the pressure on the server.
