AWS LAMBDA

Study notes & sandbox — built from the interview exercise

Lambda Tester

Local invoker for any handler(event, context) in the project root. Captures the AWS-equivalent REPORT metrics, stdout, structured JSON log lines, and CloudWatch EMF metric records — the latter two will populate automatically once the corresponding function-side improvements land.

Hit Invoke to run the selected function.
Result (JSON)
No invocation yet.
stdout / stderr
No output yet.
Structured logs (JSON-per-line on stdout — currently empty, will populate after improvement #2)
No structured logs detected.
EMF metrics (CloudWatch embedded-metric-format on stdout — populates when the function emits, e.g. sign_pdfs_optimized)
No EMF metrics detected.
Packaging (deployment sizes from the live pod — function zips, shared layer, largest deps, vs AWS caps)
