|
|
Some waits, such as:

- "wait/io/table/sql/handler"
|
|
- "wait/lock/table/sql/handler"
|
|
are implemented by calling code in a storage engine,

|
that can cause nested waits (file io, mutex, ...)
|
|
Because of partitioned tables, a table io event (on the whole table)
|
|
can contain a nested table io event (on a partition).
|
|
Because of additional debug instrumentation,
|
|
waiting on what looks like a "mutex" (safe_mutex, innodb sync0sync, ...)
|
|
can cause nested waits to be recorded.
|
|
For example, a wait on innodb mutexes can lead to:
|
|
- wait/sync/mutex/innobase/some_mutex
|
|
- wait/sync/mutex/innobase/sync0sync
|
|
- wait/sync/mutex/innobase/os0sync
|

The max depth of the event stack must be sufficient

for these low level details to be visible.

Stack of events waits.
|
|
This member holds the data for the table PERFORMANCE_SCHEMA.EVENTS_WAITS_CURRENT.
|
|
Note that stack[0] is a dummy record that represents the parent stage/statement/transaction.
|
|
For example, assuming the following tree:
|
|
- STAGE ID 100
|
|
- WAIT ID 101, parent STAGE 100
|
|
- WAIT ID 102, parent wait 101
|
|
the data in the stack will be:
|
|
stack[0].m_event_id= 100, set by the stage instrumentation
|
|
stack[0].m_event_type= STAGE, set by the stage instrumentation
|
|
stack[0].m_nesting_event_id= unused
|
|
stack[0].m_nesting_event_type= unused
|
|
stack[1].m_event_id= 101
|
|
stack[1].m_event_type= WAIT
|
|
stack[1].m_nesting_event_id= stack[0].m_event_id= 100
|
|
stack[1].m_nesting_event_type= stack[0].m_event_type= STAGE
|
|
stack[2].m_event_id= 102
|
|
stack[2].m_event_type= WAIT
|
|
stack[2].m_nesting_event_id= stack[1].m_event_id= 101
|
|
stack[2].m_nesting_event_type= stack[1].m_event_type= WAIT
|
|
|
|
The whole point of the stack[0] record is to allow this optimization
|
|
in the code, in the instrumentation for wait events:
|
|
wait->m_nesting_event_id= (wait-1)->m_event_id;
|
|
wait->m_nesting_event_type= (wait-1)->m_event_type;
|
|
This code works for both the top level wait, and nested waits,
|
|
and works without if conditions, which helps performances.
