View InnoDB disk space utilization page utilization mainly refers to the space used by each page in btee. We know that the default page size of InnoDB is 16 kb. However, the actual usage is not always full. We define the total usage bytes of all pages divided by the total number of bytes. Before analyzing the theory, we need to get a tool to check it. The instanc

In the morning to the company, customer service call said their recordings can not be opened, immediately log on to the server found that the disk is full, recording of course can not be recorded immediately back to the other disk, so now in monitoring to increase the monitoring of the disk.

of data organization. This part of management involves space utilization and disk read/write performance. 2. If different data block sizes are used, the performance will be greatly affected. The implementation scheme of database sizes of different specifications is mostly implemented based on the glibc style. The implementation method is as follows: 64-byte 128-byte, 256,512,768,102, as several specificati
