What is the page size in MySQL?
By default, all tablespaces have a page size of 16KB; you can reduce the page size to 8KB or 4KB by specifying the innodb_page_size option when you create the MySQL instance. The pages are grouped into extents of size 1MB (64 consecutive 16KB pages, or 128 8KB pages, or 256 4KB pages).
What is Page in MySQL?
InnoDB stores all records inside a fixed-size unit which is commonly called a “page” (though InnoDB sometimes calls it a “block” instead). Currently all pages are the same size, 16KB. A page contains records, but it also contains headers and trailers.
What is DB page size?
The default database page size in InnoDB is 16KB. By recompiling the code, you can set it to values ranging from 8KB to 64KB. Further, to put rows in relation to pages: The maximum row length, except for variable-length columns (VARBINARY, VARCHAR, BLOB and TEXT), is slightly less than half of a database page.
What is page size SQL?
As mentioned, in SQL Server, the page size is 8-KB. This means SQL Server databases have 128 pages per megabyte. Each page begins with a 96-byte header that is used to store system information about the page.
How big is the disk space for MySQL?
We will get 94416 MB which is around ~95 GB of disk space for our binary logs. Slave’s relay logs are basically the same as the master’s binary logs, except that they are stored on the slave side. Therefore, this calculation also applies to the slave relay logs. Spindle Disk or Solid State? There are two types of I/O operations on MySQL files:
How big should MySQL and MariaDB storage be?
If you are using binary logs, sum it up from the value we got in the previous section: 81 + 95 = 176 GB of storage for database and binary logs. Add at least 100% more room for operational and maintenance tasks (local backup, data staging, error log, operating system files, etc): 176 + 176 = 352 GB of total disk space.
Where does MySQL store data on the hard disk?
MySQL stores data in files on the hard disk under a specific directory that has the system variable “datadir”. The contents of the datadir will depend on the MySQL server version, and the loaded configuration parameters and server variables (e.g., general_log, slow_query_log, binary log).
How is the size of MySQL binary logs determined?
It is a set of log files that contain information about data modifications made on the MySQL server. The size of the binary logs depends on the number of write operations and the binary log format – STATEMENT, ROW or MIXED.
