November 2024 monthly summary for databricks/thanos: Key features delivered include Query Statistics Enablement and Configuration Refactor, enabling query frontend statistics, renaming the flag to query-frontend.query-stats-enabled, and relocating the config under CortexHandlerConfig to ensure proper initialization and propagation within request context.
