A few questions about batched writes

[marcusx2]

1. The commit seems to hang indefinitely if the client is offline, and it looks like this is intended behavior. After connection is restored, the commit is executed. How is this useful? It can freeze the entire app! I want to understand the use case for this. That doesn't happen with a Transaction for example, where if the client goes offline an error is raised and you can handle it.
2. If an error happens when trying to commit, is the batch discarded, or can I attempt to commit again the same batch? I couldn't forcibly make the batch fail, so I couldn't test this.

Thank you for your time.
