Summary

Connections is a new feature in the PlanetScale CLI designed to simplify database debugging for Postgres and Vitess (MySQL) by offering an interactive live view of database activity, refreshing about once a second and highlighting the most critical sessions. Unlike traditional methods like repeatedly running queries such as pg_stat_activity in Postgres or SHOW FULL PROCESSLIST in Vitess, Connections allows users to navigate and inspect connections using keyboard shortcuts, view a rolling history of database states, and capture sessions for later analysis. This tool is particularly useful during incidents when regular database connections are exhausted, as it uses a reserved administrative connection to ensure continued access for debugging. By providing features such as query cancellation and connection termination, Connections streamlines the troubleshooting process without requiring users to manually track syntax or connection details. It is available for use by updating to the latest version of pscale, making it an effective resource for managing active database connections in both Postgres and Vitess environments.
