[cost\_intel] Streaming API infrastructure costs exceeding token savings on high-volume logging

Disable streaming for <100ms latency requirements; aggregate chunks server-side before CloudWatch/CloudTrail logging to reduce egress fees by 40-60%

Journey Context:
Token pricing is identical for streaming vs batch, but streaming generates 50-100x more HTTP packets. On AWS Lambda behind API Gateway, this extends billed duration by 200-500ms per request due to keep-alive overhead. At 1M requests/day, streaming adds $300-500 in Lambda duration charges and $200 in API Gateway data transfer \(egress\), while batching cuts this to $50. The hidden trap: observability vendors charge per log line—streaming generates 100 log lines per request vs 1 for batch, exploding SIEM costs.
