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

Definition at line 1555 of file dict0dict.h.

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

Definition at line 1562 of file dict0dict.h.

ulint dict_sys_t::size

varying space in bytes occupied by the data dictionary table and index objects

Definition at line 1572 of file dict0dict.h.
