Answer: Use Key Visualizer for Bigtable.
To troubleshoot the issue of poor database performance experienced by a new cohort of pilot users without affecting other users, the best approach is to use Key Visualizer for Bigtable. Key Visualizer is a tool designed to help identify and diagnose performance issues in Bigtable by visualizing access patterns and hotspots. This tool can help pinpoint the exact cause of the performance degradation during the specified time frame without the need to isolate user groups or prematurely add more nodes to the cluster. Checking the Cloud Monitoring table/bytes_used metric could provide some insights but it's more general and might not directly identify the root cause of the performance issue specific to the pilot users. Isolating user groups or adding more nodes are more drastic measures that should be considered only after identifying the root cause of the issue.
