Hi @gunalaksh, the Git integration for Rasa X (IVC) is a completely optional feature. You can use Rasa X without it, and your training data will remain on your deployed SQL database.
The lock store does not use a conventional database, it uses Redis instead. The lock store does not store any conversation data, it is only there to ensure that only one Rasa Open Source node is working on a conversation at a given time. The tracker store is where the conversations are actually stored.
