Collaboration diagram for dict_sys_t:
Field Documentation
| ib_mutex_t dict_sys_t::mutex |
mutex protecting the data dictionary; protects also the disk-based dictionary system tables; this mutex serializes CREATE TABLE and DROP TABLE, as well as reading the dictionary data for a table from system tables
| row_id_t dict_sys_t::row_id |
the next row id to assign; NOTE that at a checkpoint this must be written to the dict system header and flushed to a file; in recovery this must be derived from the log records
| ulint dict_sys_t::size |
varying space in bytes occupied by the data dictionary table and index objects
| dict_table_t* dict_sys_t::sys_columns |
SYS_COLUMNS table
| dict_table_t* dict_sys_t::sys_fields |
SYS_FIELDS table
| dict_table_t* dict_sys_t::sys_indexes |
SYS_INDEXES table
| dict_table_t* dict_sys_t::sys_tables |
SYS_TABLES table
| hash_table_t* dict_sys_t::table_hash |
hash table of the tables, based on name
| hash_table_t* dict_sys_t::table_id_hash |
hash table of the tables, based on id
| ut_list_base< dict_table_t > dict_sys_t::table_LRU |
List of tables that can be evicted from the cache
| ut_list_base< dict_table_t > dict_sys_t::table_non_LRU |
List of tables that can't be evicted from the cache
