Member Function Documentation

◆ cached_time()

Implements dd::Index_stat.

◆ cardinality()

ulonglong dd::Index_stat_impl::cardinality ( ) const

◆ column_name()

Reimplemented from dd::Entity_object_impl.

◆ debug_print()

void dd::Index_stat_impl::debug_print ( String_type outb) const
overridevirtual

Implements dd::Weak_object.

◆ has_new_primary_key()

bool dd::Index_stat_impl::has_new_primary_key ( ) const
overridevirtual

Indicates that object is guaranteed to have primary key value which doesn't exist in database (e.g.

because it only will be generated using auto-increment at store() time). So it is ok for store() method to skip lookup of existing object with the same primary key and simply try to insert new object into the table.

Reimplemented from dd::Entity_object_impl.

◆ id()

Object_id dd::Index_stat_impl::id ( ) const
inlineoverridevirtual

The unique dictionary object id.

Reimplemented from dd::Entity_object_impl.

◆ impl() [1/2]

const Entity_object_impl * dd::Index_stat_impl::impl ( ) const

Reimplemented from dd::Entity_object_impl.

◆ impl() [2/2]

Entity_object_impl * dd::Index_stat_impl::impl ( )

Reimplemented from dd::Entity_object_impl.

◆ index_name()

const String_type & dd::Index_stat_impl::index_name ( ) const
inlineoverridevirtual

Implements dd::Index_stat.

◆ is_persistent()

bool dd::Index_stat_impl::is_persistent ( ) const
inlineoverridevirtual

Is dictionary object persistent in dictionary tables ?

Reimplemented from dd::Entity_object_impl.

◆ name()

const String_type & dd::Index_stat_impl::name ( ) const
inlineoverridevirtual

Reimplemented from dd::Entity_object_impl.

const Object_table & dd::Index_stat_impl::object_table ( ) const
overridevirtual

◆ register_tables()

void dd::Index_stat_impl::register_tables ( Open_dictionary_tables_ctx otx)
static

The requirement is that we should be able to update Table_stats and Index_stats DD tables even when someone holds global read lock, when we execute ANALYZE TABLE.
