MV_QUERY_ACTIVITIES
This view provides a high-level summary profile of all the queries that ran recently in the workspace.
Each row describes a query sent to the workspace, as well as queries sent between nodes.
Column name | Description |
---|---|
| The name of the high-level activity. |
| The de-parameterized text of the query. |
| The name of the database associated with the query, or |
| Milliseconds spent running on a CPU. If |
| Milliseconds spent waiting for a CPU to become available. A non-zero value indicates that there were more concurrent tasks in the workload than there were CPUs on which to run them. If this value is a significant amount of elapsed time, the workload is likely issuing its queries faster than the hardware can handle. Investigate the tasks with the highest |
| Wall clock milliseconds elapsed during execution. |
| Milliseconds spent waiting on locks and condition variables, excluding row locks. This isn’t solely wait time due to contention on data structures because it also includes some time spent waiting for events in general. |
| Milliseconds spent waiting for physical disk I/O to complete. If this value is high, it may indicate excessive time to commit transactions to storage. You may need hardware which supports a faster write rate, or you may need to investigate whether other processes are issuing too much I/O and introducing unwanted variability. Check which other queries are using |
| Milliseconds spent waiting for sockets to be ready to send or receive data. This may indicate that leaves are slow to respond to a query, or that a distributed join involves a large data transfer. If this counter has a noticeable delay, check what other queries are consuming |
| Number of bytes SingleStoreDB Cloud sent and received to sockets. |
| Number of bytes that SingleStoreDB Cloud read and wrote to the filesystem or the in memory transaction log. |
| |
| Number of page faults which required disk I/O to resolve. |
| The number of instances which were running at the end of the interval. |
| The number of instances which completed successfully during the interval. |
| The number of instances which completed unsuccessfully during the interval. |
| The number of warnings generated during query execution. |
| A high-level information of the plan. |
