Shorten some VARCHAR attributes to a more reasonable length. INNODB_METRICS: Rename the column STATUS to ENABLED, and make it Boolean. Replace with INT(1) many Boolean attributes that were declared as VARCHAR containing 'NO','YES','disabled','enabled','Uninitialized','Initialized'. Replace some VARCHAR attributes with ENUM. Replace some BIGINT with INT when 32 bits are sufficient. Remove INNODB_SYS_TABLESPACES.SPACE_TYPE. The type of a tablespace can be derived from the tablespace ID. A fixed number is used for the system tablespace and the temporary tablespace. All other tablespaces are single-table or single-partition tablespaces. i_s_locks_row_t::lock_type, lock_get_type_str(): Remove. This is a redundant field. Table and record locks can be distinguished by whether i_s_locks_row_t::lock_index is NULL. fill_trx_row(): Do not unnecessarily copy the constant strings that trx->op_info is pointing to. i_s_locks_row_t::lock_mode: Replace string with integer. lock_get_mode_str(), lock_get_trx_id(), lock_get_trx(): Remove. field_store_ulint(): Remove.
