Bot framework directline conversation data

Question

I am using the Bot framework / DirectLine within a custom app. I replaced the default BotDataStore with a custom one (table storage using the bot builder extension).

But still, the conversation (I am talking about the collection of activities, not the state in UserData / PrivateConversationData) is stored somewhere else. Indeed, when I call directline API GetActivities with a watermark, I can get the history of the conversation even after deleting the content of my table storage.

Is there a way to get the conversation data ONLY stored in a custom storage (like a table storage) ?

Thx

The Direct Line is a bot communication channel, not a message store. In order to account for temporary connection issues, and provide stability, the Direct Line has a temporary cache of messages. If a client loses connection, messages sent during the downtime can be retrieved by replaying from the last watermark.
