Notebook disconnects are one of the most frustrating user experiences in the enterprise world of the client-server jupyter model. If the user refreshes the notebook or loses internet access while executing a long-running notebook on a remote server, data or notebook executions will be lost. Re-running everything again will lead to increased resource utilization, waste users' time and impact user productivity.

In this talk, we’ll describe how we, at Meta, built a reliable solution to reconnect the notebook to an existing session and recover the notebook executions from that session on the server to the client. This workflow has already been deployed successfully in Bento, Meta’s Jupyter distribution. This talk will navigate through the client-server architecture of jupyter and then, get deeper into the technical solution to session reconnection and recovery for notebook executions.

Through this talk, we want to bring awareness among the audience on the importance of recovery of notebook executions, how we implemented a reliable solution for seamless recovery at Meta, and more explorations to persist notebook sessions, save compute and improve user productivity.
