Worker Nodes Concept

POSDA worker nodes provide a way to move background processes off the POSDA Server.

  • Each node handles one background process at a time
  • You can have as many nodes as you want (within reason)
  • Nodes can be added/deleted dynamically
  • Queues are also configurable, but less dynamic

Note: A queue can contain many (potentially thousands) of background processes.
