Record thresholds identify the minimum number of active records expected for the specific record they're applied to and can be defined for each Source, Studio and Target records.
When Record Thresholds are defined, Studio Job Orchestration will automatically pause a job if the count of active records that are about to be created by that job falls below the defined threshold. This prevents the propagation of incomplete or invalid records into Studio or out to Target Applications depending on where in the process the threshold has not been met.
