One or more sessions can be in a delayed state, waiting for rows to be inserted, at the time you populate an unpopulated queue table. Vantage reinstates one or more of those delayed sessions, up to the number of rows inserted into the table, to enable the sessions to continue their consume mode requests.

Session Mode Use the following after any INSERT statements to make those rows visible to any delayed sessions
