Instrument cache warmup phases with OpenTelemetry spans for better startup and perf visibility

Instrument cache warmup phases with OpenTelemetry spans for better startup and perf visibility targets a $20.0B = Global observability & APM market (~$20B global spend across enterprises, cloud providers, and managed services) total addressable market with medium saturation and a year-over-year growth rate of 18% CAGR for observability and APM.

Key trends driving demand: OpenTelemetry standardization -- accelerates adoption of vendor-agnostic instrumentation and enables a common span schema for cache warmups.; Serverless & edge adoption -- increases sensitivity to cold starts and cache warmup behavior, making warmup visibility more valuable.; Rising cloud costs & optimization -- organizations seek granular traces to tie cache warmup to request latency and egress costs.; AI-driven root-cause analysis -- automated pattern detection in traces lowers the barrier to surfacing warmup issues and recommending fixes..
