Variable Documentation

◆ srv_skip_temp_table_checks_debug

bool srv_skip_temp_table_checks_debug = true

Control if extra debug checks need to be done for temporary tablespace.

Default = true that is disable such checks. This variable is not exposed to end-user but still kept as variable for developer to enable it during debug.

◆ srv_sys_space

ib::fsp::SysTablespace srv_sys_space(TRX_SYS_SPACE, FIL_TYPE_TABLESPACE)	(	TRX_SYS_SPACE	,
		FIL_TYPE_TABLESPACE
	)

The server header file is included to access opt_initialize global variable.

If server passes the option for create/open DB to SE, we should remove such direct reference to server header and global variable The control info of the system tablespace.

◆ srv_tmp_space

ib::fsp::SysTablespace srv_tmp_space(dict_sys_t::s_temp_space_id, FIL_TYPE_TEMPORARY)	(	dict_sys_t::s_temp_space_id	,
		FIL_TYPE_TEMPORARY
	)

The control info of a temporary table shared tablespace.

◆ sys_tablespace_auto_extend_increment

ulong sys_tablespace_auto_extend_increment

If the last data file is auto-extended, we add this many pages to it at a time.

We have to make this public because it is a config variable.
