Neither of our temporal services have **sample** in their logs (picture 1). We have a dynamic config loaded (picture 2 and 3) . But seems our workflows goes away from the visibility db anyway. I can find them using the tctl and they seem to still be running (picture 4).

Just to confirm, are you using Cassandra persistence for visibility database?  
Can you share the config for persistence section?  
Can you confirm if the visibility keyspace is created in Cassandra? Most likely `temporal_visibility` or whatever it says in the config.

> But seems our workflows goes away from the visibility db anyway.

You said `goes away`, does that mean it was there for sometime and gets deleted? What is the retention for your namespace? Workflows are suppose to be deleted from visibility after the retention interval upon completion.

Can you also share the result of

```auto
tctl wf list

```

```auto
tctl wf list --open

```

Those are the cassandra keyspaces
