InnoDB Memcached configurations

Function Documentation

meta_cfg_info_t* innodb_config	(	const char *	name,
		size_t	name_len,
		hash_table_t **	meta_hash
	)

If the hash table (meta_hash) is NULL, then initialise the hash table with data in the configure tables. And return the "default" item. If there is no setting named "default" then use the first row in the table. This is currently only used at the engine initialization time. If the hash table (meta_hash) is created, then look for the meta-data based on specified configuration name parameter. If such metadata does not exist in the hash table, then add such metadata into hash table.

Returns

meta_cfg_info_t* structure if configure option found, otherwise NULL

Parameters

name	in: config option name
name_len	in: name length
meta_hash	in/out: engine hash table. If NULL, it will be created and initialized

void innodb_config_free

(

meta_cfg_info_t *

item

)

This function frees meta info structures

Parameters

item	in: meta info structure

meta_cfg_info_t* innodb_config_meta_hash_init

(

hash_table_t *

meta_hash

)

This function opens the "containers" table, reads in all rows and instantiates the metadata hash table.

Returns

the default configuration setting (whose mapping name is "default")

bool innodb_verify

(

meta_cfg_info_t *

info

)

This function verifies the table configuration information, and fills in columns used for memcached functionalities (cas, exp etc.)

Returns

true if everything works out fine

Parameters

info	in: meta info structure

Here is the call graph for this function:

ib_err_t innodb_verify_low	(	meta_cfg_info_t *	info,
		ib_crsr_t	crsr,
		bool	runtime
	)

This function verifies the table configuration information on an opened table, and fills in columns used for memcached functionalities (cas, exp etc.)

Returns

true if everything works out fine

Parameters

info	in/out: meta info structure
crsr	in: crsr
runtime	in: verify at the runtime

Variable Documentation

option_t config_option_names[]

Initial value:

{
        {OPTION_ID_COL_SEP, COLUMN_SEPARATOR, {"|", 1}},
        {OPTION_ID_TBL_MAP_SEP, TABLE_MAP_SEPARATOR, {".", 1}}
