alloc_identifier()

std::string_view anonymous_namespace{p_s.cc}::alloc_identifier	(	PSI_server_data_lock_container *	container,
		PSI_identifier	kind,
		const std::string &	id_str
	)

Allocate identifier in performance schema container.

The string is allocated in the cache of the container and is owned by that cache. Therefore the returned std::string_view is only valid for as long as the cache is not cleared by a call to PFS_data_cache::clear() which occurs in:

• PFS_data_lock_wait_container::clear()
• PFS_data_lock_wait_container::shrink()
• PFS_data_lock_container::clear()
• PFS_data_lock_wait_container::shrink()

  Parameters

  [in]	container	The container to fill
  [in]	kind	The identifier kind
  [in]	id_str	The identifier string

  Returns

  view of the cached string

parse_table_path()

parsed_table_path anonymous_namespace{p_s.cc}::parse_table_path	(	PSI_server_data_lock_container *	container,
		const char *	table_path
	)

Parse a table path string.

Isolate the table schema, name, partition and sub partition from a table path string. Convert these strings and store them in the performance schema container.

Note

String returned are not zero terminated.

Parameters

[in]	container	The container to fill
[in]	table_path	The table path string

Returns

parsed fragments of the table name pointing to cached strings
