mv_activities_extended_cumulative

The mv_activities_extended_cumulative view in the information_schema database is a detailed profile of completed and currently running tasks on all nodes of the cluster.

It holds a row per activity. Each row describes completed and currently running instances of its activity. It reports the sum of the profiling statistics of each instance, as collected over its lifetime.

mv_activities_extended_cumulative may only be queried while connected to an aggregator node.

We recommend against extensive use of this table. It doesn’t accurately describe past system behavior because it doesn’t include all completed instances. This is because historical task statistics may be discarded by SingleStore DB at unspecified times.
