Heartbeats

Functional design​

  • Client subscribes to the sys.Heartbeat30 table in any Workspace
    • ~freq.Interval30Seconds~covrd1✅: Server sends heartbeat every 30 seconds
    • ~freq.ZeroKey~covrd2✅: Heartbeat is generated for AppQName{} and NullWSID
    • ~freq.SingleNotification~covrd3✅: If the client subscribes to sys.Heartbeat30 in multiple workspaces, the server sends only one heartbeat per 30 seconds to the client
    • It is not necessary to insert a record to the sys.Heartbeat30 singleton

Technical design​

  • ~cmp.wsingleton.Heartbeat30~covrd4✅
    • No ACL
  • ~it.Heartbeat30~covrd5✅
