Function mariadb_sys::handler_start_psi_batch_mode

pub unsafe extern "C" fn handler_start_psi_batch_mode(
    this: *mut handler
)

Put the handler in ‘batch’ mode when collecting table io instrumented events. When operating in batch mode:

• a single start event is generated in the performance schema.
• all table io performed between @c start_psi_batch_mode and @c end_psi_batch_mode is not instrumented: the number of rows affected is counted instead in @c m_psi_numrows.
• a single end event is generated in the performance schema when the batch mode ends with @c end_psi_batch_mode.
