The events_waits_current table has these columns: THREAD_ID, EVENT_ID The thread associated with the event and the thread current event number when the event starts. The THREAD_ID and EVENT_ID values taken together uniquely identify the row. No two rows have the same pair of values. EN...

The events_waits_current table contains the status of a thread's most recently monitored wait event, listing one event per thread. The table contains the following columns: ColumnDescription THREAD_ID Thread associated with the event. Together with EVENT_ID uniquely identifies the row. EVENT_ID...

setup_consumers中的事件表有层级之分 ,我们可以通过上面看到有global、thread、current、history、history_long,他们之间的层级如下: global_instrumentation thread_instrumentation events_waits_current events_waits_history events_waits_history_long events_stages_current ...
Another factor is the number of hops: as a packet makes its way around the internet, it makes pit stops at routing stations, which might hold the data in memory as it waits in line to be sent to the next stop. This takes time, and may happen several hundred times for a long distanc...
TOTAL_WAITS: the total number of waits for the event. TIME_WAITED: the total wait time of the event. TOTAL_TIMEOUTS: the total number of wait timeouts for the event. AVERAGE_WAIT: the average wait time for the event. The following example shows how to query the statistics of wait event...
One process will continue while the other waits for it to complete. IPC:AuroraOptimizedReadsCacheWriteStop A process is waiting for the background writer to stop writing into Optimized Reads tiered cache. IPC:BackupWaitWalArchive A process is waiting for write-ahead log (WAL) files required for...
This event fires before image files and other resources have loaded, while the native load event waits until all page resources are finally available. If you use the standard YUI sandbox pattern with scripts at the bottom, there is a good chance that the domready moment will occur after it ...
Considering that this crash has been consistently reported for TABLE EVENTS_WAITS_HISTORY_LONG, but never for TABLE EVENTS_WAITS_CURRENT, I suspect that the root cause is located in copy_events_waits(). The code uses a memcpy, which may copy different bytes of the 64 bits wait->m_object_...
