This article mainly introduces "the new features corresponding to the compression table of MySQL5.5". In the daily operation, I believe that many people have doubts about the corresponding new features of the compression table of MySQL5.5. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "the new features corresponding to the compression table of MySQL5.5". Next, please follow the editor to study!
1. Compressed tables are only valid for single tablespaces, so set the following parameters:
Innodb_file_per_table
Innodb_file_format = Barracuda
two。 Build a table OPTIONS.
ROW_DATEFORMAT = COMPRESSED
KEY_BLOCK_SIZE = (1, 2, 4, 8, 16.)
Exactly how much KEY_BLOCK_SIZE size is set depends on the data distribution of the table to be compressed. To put it simply, you can insert tables with different structures with the same data, and then OK the size of the tables on disk.
3. There's one more thing to note.
Set the INNODB compression table, so your INNODB_BUFFER_POOL_SIZE should be at least twice the size before. Because two copies of PAGE with different SIZE but consistent data should be kept in the buffer pool. In this way, the overhead of memory is increased.
At this point, the study of "the new features corresponding to the compression table of MySQL5.5" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
