Detailed Description

State variables of the mtr.

Member Data Documentation

◆ m_flush_observer

Flush_observer* mtr_t::Impl::m_flush_observer

Flush Observer.

◆ m_inside_ibuf

bool mtr_t::Impl::m_inside_ibuf

true if inside ibuf changes

◆ m_log

mtr_buf_t mtr_t::Impl::m_log

mini-transaction log

◆ m_log_mode

mtr_log_t mtr_t::Impl::m_log_mode

specifies which operations should be logged; default value MTR_LOG_ALL

◆ m_magic_n

ulint mtr_t::Impl::m_magic_n

For checking corruption.

◆ m_marked_nolog

bool mtr_t::Impl::m_marked_nolog

true if mtr is forced to NO_LOG mode because redo logging is disabled globally.

In this case, mtr increments the global counter at start and must decrement it back at commit.

◆ m_memo

mtr_buf_t mtr_t::Impl::m_memo

memo stack for locks etc.

◆ m_modifications

bool mtr_t::Impl::m_modifications

true if the mini-transaction might have modified buffer pool pages

◆ m_mtr

mtr_t* mtr_t::Impl::m_mtr

Owning mini-transaction.

◆ m_n_log_recs

uint32_t mtr_t::Impl::m_n_log_recs

Count of how many page initial log records have been written to the mtr log.

◆ m_shard_index

size_t mtr_t::Impl::m_shard_index

Shard index used for incrementing global counter at start.

We need to use the same shard while decrementing counter at commit.

◆ m_state

mtr_state_t mtr_t::Impl::m_state

State of the transaction.
