The original title is: "Change Data Capture in 2026: Supabase Webhooks, Prisma Pulse, and the 'Thundering Herd' Problem"

Short summary

A practical comparison of Supabase Database Webhooks and Prisma Pulse for Change Data Capture in Postgres, focusing on the 'thundering herd' problem when bulk updates fire thousands of webhooks simultaneously. The article recommends adding a queue-based resilience layer (BullMQ, SQS, or services like InstaWebhook) to accept fast, retry with backoff, and dead-letter failures.

• •Supabase Webhooks and Prisma Pulse both turn Postgres row changes into events but fail under bulk updates
• •The 'thundering herd' problem causes rate-limit failures when thousands of webhooks fire at once
• •Fix: add a queue layer for fast intake, backoff retries, and dead-letter queues for failed deliveries
