Transaction Prioritization

There are three buckets for transactions in the VOSS-4-UC system Priority Queue, namely high, medium and low priority:

  1. High Priority:
    • Self-service transactions: carried out by end users on the Self-Service interface
  2. Medium Priority:
    • MACD operations on the VOSS-4-UC GUI by Administrator users
    • API-based provisioning (HIL)
    • Any other transaction not in the Low Priority bucket
  3. Low Priority:
    • Data Sync (LDAP, any device import transaction)
    • Bulk load transactions
    • Data import (import of data in JSON format)

From the Command Line Interface (CLI), a command is available to modify the default number of queue workers:

  • Use voss workers to show the current number of queue workers. The default is 30.
  • Use voss workers <number> set the number of queue workers.

An adjustment of the number of queue workers will impact on the number of parallel transactions that will run, which is a factor of this value as well the queue priority bucket to which the transaction belongs.

For example, Data Sync transactions may execute asynchronous workflows which are executed in parallel, or a Bulk Load transaction may have the Parallel flag set to True.
