Mysql Master/Slave configuration for read/write splitting and mysql Master/Slave read/write splitting In order to solve a large number of concurrent accesses to large websites, distributed load balancing is far from enough. At the data service layer and data access layer, if the traditional data structure is used, or only one server is used, the database will inevitably crash and data will be lost due to so

Linux dd command to test the read/write speed of the USB flash drive and the dd read/write speed 1.

The Oracle database uses undo to ensure consistent read and dirty read. User A updates the table and does not submit the table. User B queries the table, unsubmitted updates cannot appear in the user's query results. Instance simulation: the data in the test table is as follows: 1. User A queries: SQL> select * from test; id name ---------- -------- 1 A 2 B2, user B: update test set name = 'C' where id = 1;
