Statistics

Tantor PipelineDB includes a number of statistics-gathering views that provide insight into how the system is behaving. Statistics can be broken down by process, continuous view, stream, or viewed globally across the entire installation.

Each statistics view is described below.

pipelinedb.proc_stats

Statistics broken down by worker and combiner processes. These statistics only last for the duration of the underlying processes.
