Member Data Documentation

m_enabled

bool PFS_table_share::m_enabled

True if table instrumentation is enabled.

This flag is computed from the content of table setup_objects.

m_key

PFS_table_share_key PFS_table_share::m_key

Search key.

m_key_count

uint PFS_table_share::m_key_count

Number of indexes.

m_lock

pfs_lock PFS_table_share::m_lock

Internal lock.

m_page

PFS_opaque_container_page* PFS_table_share::m_page

Container page.

m_race_index_stat

std::atomic<PFS_table_share_index *> PFS_table_share::m_race_index_stat[MAX_INDEXES+1]

private

Table indexes stats.

m_race_lock_stat

std::atomic<PFS_table_share_lock *> PFS_table_share::m_race_lock_stat

private

Table locks statistics.

m_refcount

std::atomic<int> PFS_table_share::m_refcount

private

Number of opened table handles.

m_timed

bool PFS_table_share::m_timed

True if table instrumentation is timed.

This flag is computed from the content of table setup_objects.
