Detailed Description

Container class for all table cache instances in the system.

Member Function Documentation

void Table_cache_manager::assert_owner_all ( )

Assert that caller owns locks on all instances of table cache.

void Table_cache_manager::assert_owner_all_and_tdc ( )

Assert that caller owns locks on all instances of table cache and table definition cache.

uint Table_cache_manager::cache_index ( Table_cache * cache ) const [inline]

Get index for the table cache in container.

uint Table_cache_manager::cached_tables ( )

Get total number of used and unused TABLE objects in all table caches.

Note:: Doesn't require acquisition of table cache locks if inexact number of tables is acceptable.

void Table_cache_manager::destroy ( )

Destroy all instances of table cache which were used by server.

void Table_cache_manager::free_all_unused_tables ( )

Free all unused TABLE objects in all table cache instances.

void Table_cache_manager::free_table	(	THD *	thd,
		enum_tdc_remove_table_type	remove_type,
		TABLE_SHARE *	share
	)

Remove and free all or some (depending on parameter) TABLE objects for the table from all table cache instances.

Parameters:

thd	Thread context
remove_type	Type of removal.

Parameters:

share TABLE_SHARE for the table to be removed.

Table_cache* Table_cache_manager::get_cache ( THD * thd ) [inline]

Get instance of table cache to be used by particular connection.

bool Table_cache_manager::init ( void )

Initialize all instances of table cache to be used by server.

Return values:

false	- success.
true	- failure.

void Table_cache_manager::lock_all_and_tdc ( )

Acquire locks on all instances of table cache and table definition cache (i.e. LOCK_open).

void Table_cache_manager::print_tables ( )

Print debug information for the contents of all table cache instances.

void Table_cache_manager::unlock_all_and_tdc ( )

Release locks on all instances of table cache and table definition cache.

Maximum supported number of table cache instances.
