Detailed Description

Called from functions in sdi.cc if the dd object resides in an SE supporting SDI storage in tablespaces.

Note

There is no function for dropping the Tablespace SDI. Dropping a tablespace implies that all SDIs in it are dropped also.

Function Documentation

drop_all_sdi() [1/2]

bool dd::sdi_tablespace::drop_all_sdi	(	THD *	,
		const handlerton &	,
		const Partition &
	)

Deletes all SDIs with SDI_TYPE_TABLE from the partition tablespace, or sub-partition tablespaces in case of a sub-partitioned table.

SDIs with SDI_TYPE_TABLESPACE are only deleted if their tablespace id does not match the current tablespace id of the tablespace being deleted from.

drop_all_sdi() [2/2]

bool dd::sdi_tablespace::drop_all_sdi	(	THD *	,
		const handlerton &	,
		const Table &
	)

Deletes all SDIs with SDI_TYPE_TABLE from the table tablespace.

In case of a partitioned table, SDIs are deleted from all partition tablespaces. SDIs with SDI_TYPE_TABLESPACE are only deleted if their tablespace id does not match the current tablespace id of the tablespace being deleted from.

drop_tbl_sdi()

bool dd::sdi_tablespace::drop_tbl_sdi	(	THD *	thd,
		const handlerton &	hton,
		const Table &	table,
		const Schema &	schema
	)

Looks up the relevant tablespaces for the table and drops the table SDI in each.

Note

When the last table in a schema is dropped from a tablespace the schema SDI should also be dropped. But leaving them is not a big problem as the schema SDIs are small (they only contain the default charset for the schema).

store_tbl_sdi()

bool dd::sdi_tablespace::store_tbl_sdi	(	THD *	thd,
		handlerton *	hton,
		const dd::Sdi_type &	sdi,
		const dd::Table &	table,
		const dd::Schema &	schema
	)

Looks up the relevant tablespaces for the table and stores the table SDI in each.

store_tsp_sdi()

bool dd::sdi_tablespace::store_tsp_sdi	(	handlerton *	hton,
		const Sdi_type &	sdi,
		const Tablespace &	tblspc
	)

Stores the tablespace SDI in the tablespace.
