The New CQL Optimization Dashboard in ScyllaDB Monitoring Stack 2.2

ScyllaDB Monitoring Stack version 2.2 introduces a new CQL Optimization Dashboard designed to help users identify and resolve potential issues with queries, data models, and drivers to improve performance. The dashboard features gauges and graphs that highlight various inefficiencies such as non-prepared queries, non-token-aware drivers, non-paged queries, reversed CQL reads, and ALLOW FILTERING queries, all of which can affect the system's performance. Users are encouraged to keep these metrics low, ideally close to zero, to ensure optimal performance. The dashboard also addresses cross-data-center read requests that can add unnecessary overhead, emphasizing the importance of monitoring these metrics continuously during application development and operation. Through this tool, ScyllaDB aims to provide users with actionable insights to enhance their database operations and performance.
