Fixed multiple technical inaccuracies in InfluxDB 3 runtime and performance documentation:
Testing status:
1. ✅ Replaced FILTER clause with CASE statements - TESTED
2. ✅ Fixed API endpoint syntax - uses q and db fields, not query and database
3. ✅ Removed invalid system.runtime_metrics table reference
4. ✅ Validated all system tables exist: queries, compaction_events, parquet_files, etc.
Changes:
- Corrected SQL queries to use CASE WHEN instead of non-existent FILTER clause
- Fixed InfluxQL API endpoint to use correct query parameters (q and db)
- Removed references to non-existent system.runtime_metrics table
- Added proper system table references (system.queries, system.compaction_events)
- Updated runtime thread allocation documentation with accurate thread counts
- Clarified performance monitoring queries and metrics collection
- Add comprehensive runtime architecture documentation covering thread pools, resource allocation, and concurrency model
- Add metrics monitoring guide with Prometheus endpoint configuration and key metrics reference
- Add performance tuning documentation with thread pool optimization, memory settings, and resource planning
- Add clustering configuration documentation for InfluxDB 3 Enterprise
- Update CLI serve command documentation with new runtime and metrics flags
This addresses the need for detailed documentation on:
- How InfluxDB 3 manages threads and system resources
- How to monitor and observe InfluxDB 3 performance metrics
- How to tune runtime parameters for optimal performance
- How to configure clustering in Enterprise deployments
