I think this should be covered with a tracing feature.

We already have {SYS.SQL_QUERIES}, {SYS.SCAN_QUERIES},
{SYS.SQL_QUERIES_HISTORY}.
these views provide data similar to what you expected.
Can you, please, take a look at this view?

> When in the production environment exist some cluster performance issues
> usually it leads to the large striped executor queue size.
> The number of tasks in the queue can observe by
> {StripedExecutorMXBean#getTotalQueueSize} metric. In the case queue size
> becomes large it's useful to have the ability to know what tasks are waiting
> for execution in the thread pool.
> Especially, for dealing with failover scenarios.
> We should create a system views to expose information about striped executor
> services queue.
