mtr_t::trx: New public const data member. If it is nullptr, per-connection statistics will not be updated. The transaction is not necessarily in active state. We may merely use it as an "anchor" for buffering updates of buf_pool.stat.n_page_gets in trx_t::pages_accessed. As part of this, we try to create mtr_t less often, reusing one object in multiple places. Some read operations will invoke mtr_t::rollback_to_savepoint() to release their own page latches within a larger mini-transactions. |
