A New Way to Debug Query Performance in Cloud Dedicated

InfluxDB's new `--perf-debug` flag in version 2.12.0 of the `influxctl` command enhances query optimization and debugging by providing real-time execution metrics without displaying query results. This feature is specifically beneficial for Cloud Dedicated and Clustered environments, allowing users to remain within the command-line interface as they refine their queries. The `--perf-debug` flag outputs metrics in a human-readable tabular format by default, while JSON format can be specified for programmatic use. The flag helps in understanding client-server metrics, including network latency, cache performance, and compaction impacts on query execution. The feature supports the exploration of query performance variations by considering factors such as cache warmup, data density, and partitioning, and it encourages experimentation to optimize performance effectively.
