Function Documentation

dict_sdi_create()

bool dict_sdi_create

(

dd::Tablespace *

tablespace

)

Create SDI in a tablespace.

This API should be used when upgrading a tablespace with no SDI.

Parameters

[in,out]

tablespace

tablespace object

Return values

false	success
true	failure

dict_sdi_delete()

bool dict_sdi_delete	(	const dd::Tablespace &	tablespace,
		const dd::Table *	table,
		const sdi_key_t *	sdi_key
	)

Delete SDI from tablespace.

Parameters

[in]	tablespace	tablespace object
[in]	table	table object
[in]	sdi_key	SDI key to uniquely identify the tablespace object

Return values

false	success
true	failure

dict_sdi_drop()

bool dict_sdi_drop

(

dd::Tablespace *

tablespace

)

Drop SDI in a tablespace.

This API should be used only when SDI is corrupted.

Parameters

[in,out]

tablespace

tablespace object

Return values

false	success
true	failure

dict_sdi_exists()

static dberr_t dict_sdi_exists ( const dd::Tablespace &  dd_space, uint32_t *  space_id  )

static

Check if SDI Index exists in a tablespace.

Parameters

[in]	dd_space	DD tablespace object
[in,out]	space_id	space_id from tablespace object

Returns

DB_SUCCESS if SDI exists, else return DB_ERROR, DB_TABLESPACE_NOT_FOUND

dict_sdi_get()

bool dict_sdi_get	(	const dd::Tablespace &	tablespace,
		const sdi_key_t *	sdi_key,
		void *	sdi,
		uint64_t *	sdi_len
	)

Retrieve SDI from tablespace.

Parameters

[in]	tablespace	tablespace object
[in]	sdi_key	SDI key
[in,out]	sdi	SDI retrieved from tablespace
[in,out]	sdi_len	in: size of memory allocated out: actual length of SDI

Return values

false	success
true	in case of failures like record not found, sdi_len is UINT64MAX_T, else sdi_len is actual length of SDI

dict_sdi_get_keys()

bool dict_sdi_get_keys	(	const dd::Tablespace &	tablespace,
		sdi_vector_t &	vector
	)

Get the SDI keys in a tablespace into the vector provided.

Parameters

[in]	tablespace	tablespace object
[in,out]	vector	vector to hold SDI keys

Return values

false	success
true	failure

dict_sdi_report_error() [1/2]

static void dict_sdi_report_error ( const char *  operation, const dd::Table *  table, const dd::Tablespace &  tablespace  )

static

Report error on failure.

Calls dict_sdi_report_error(int errornum, const char *operation, const dd::Table *table, const dd::Tablespace &tablespace) with errornum=SDI_OPERATION_FAILED (for compatibility with existing code).

Parameters

[in]	operation	SDI set or delete
[in]	table	table object for which SDI is serialized
[in]	tablespace	tablespace where SDI is stored

dict_sdi_report_error() [2/2]

static void dict_sdi_report_error ( int  errornum, const char *  operation, const dd::Table *  table, const dd::Tablespace &  tablespace  )

static

Report error on failure.

Parameters

[in]	errornum	MySQL error number (for my_error()) (Must take 4 string arguments, in the same way as ER_SDI_OPERATION_FAILED)
[in]	operation	SDI set or delete
[in]	table	table object for which SDI is serialized
[in]	tablespace	tablespace where SDI is stored

dict_sdi_set()

bool dict_sdi_set	(	handlerton *	hton,
		const dd::Tablespace &	tablespace,
		const dd::Table *	table,
		const sdi_key_t *	sdi_key,
		const void *	sdi,
		uint64_t	sdi_len
	)

Insert/Update SDI in tablespace.

Parameters

[in]	hton	handlerton object
[in]	tablespace	tablespace object
[in]	table	table object
[in]	sdi_key	SDI key to uniquely identify the tablespace object
[in]	sdi	SDI to be stored in tablespace
[in]	sdi_len	SDI length

Return values

false	success
true	failure
