.. _innodb_files_extend:
================================
Support of Multiple Page Sizes
================================
In standard |InnoDB|, the size of the read-ahead area is computed dynamically, but it always has the same value. This change makes the size fixed, avoiding unuseful computations.
This feature adds a new system variable for setting it.
System Variables
================
.. variable:: innodb_page_size

:conf: Yes
:scope:
:dyn: No
:vartype: ULONG

:range: 1 « 12 to 1 « ``UNIV_PAGE_SIZE_SHIFT_MAX``
**EXPERIMENTAL**: The universal page size of the database. Changing for an existing database is not supported. Use at your own risk!
