Module: Perfgate::Serialization::RunResult

Defined in:
lib/perfgate/serialization/run_result.rb

Overview

Builds the schema_version 1 run-result document described in spec section 14.1. Milestone 5 will add source metadata; fingerprinting (spec section 15) is populated here so the comparison engine can decide compatibility without re-deriving it from scratch.

def metric_keys(samples)
  samples.each_with_object([]) { |sample, keys| keys.concat(sample.keys) }.uniq
end

.summarize(samples) ⇒ Object

Every metric key present in at least one sample gets its own summary block (spec section 14.1 shows this for duration_ns, but the same shape applies to sql_count, sql_duration_ns, etc. once those metrics are enabled).
