And store the information in the memory, and then record it into the binary file, this will cause the slave server to lag behind the master server, but this is also good, if you have an error operation, in this time, it is OK to back up data from the server immediately, which requires the mysql administrator to grasp.

change minimizes performance loss because it reduces the number of table scans required to update all rows (slave_rows_search_algorithms parameter TABLE_SCAN by default, INDEX_SCAN, HASH_SCAN ). The transaction-write-set-extraction parameter is enabled by default: write set extraction is used to start group replication for the user or trace the master on the master server using WRITESET-based dependency. Enable Binary log expiration time by default

Windows.However, sometimes the compile time can pass, but the runtime prompts such errors: "X error of failed reques:badwindows (invalid Windows parameter)"By its meaning, the Windows parameter of OpenGL in the program is set incorrectly, not actually. This problem is usually due to system updates, such as running the sudo apt-get Upgrade command, and so on, updating the X service in the system to overwrite some files of the previously installed Nvidia graphics card, and re-install the Nvidia g
