Data Dam

Absorb the spike. Ship every order.

A durable webhook buffer for Shopify stores. Data Dam sits in front of your backend and absorbs flash-sale spikes, restock stampedes, influencer drops, and bot traffic — so every order arrives, even when your systems can’t keep up in the moment.

Why it exists

Flash sales break backends. Orders shouldn't die because of it.

A successful drop or restock announcement can send more traffic at a Shopify backend in ten minutes than it normally sees in a week. Webhooks queue up, timeouts cascade, and the backend that processes orders falls behind or falls over — taking real orders with it.

Data Dam sits between Shopify and your backend as a durable proxy. You paste in your existing backend URL and get back a Data Dam URL to use instead. From that point on, every webhook is written to a crash-safe log before your backend ever sees it, and delivered back out at a rate your systems can actually absorb.

Features

Built for the burst, not the average

No dashboards to configure and no infrastructure to run. Data Dam is designed to be wired up once and then forgotten about — until the day it matters.

No-code integration

Paste your backend URL in, get a durable proxy URL back. No SDK, no code changes, no deploy.

Write-ahead log

Every partition is durably logged before delivery, so a webhook is never held only in memory.

Crash recovery

If your backend goes down mid-burst, Data Dam keeps the queue intact and resumes delivery when it's back — nothing is lost.

Deterministic load-shedding

Staggered, rate-controlled delivery tuned for bursty real-world traffic, not average-case load.

Built for Shopify spikes

Purpose-built for flash sales, restocks, influencer drops, and bot traffic — the traffic shapes generic tools weren't designed for.

Zero maintenance

Wire it up once. No dashboards to babysit, no scaling decisions to make during the sale itself.

Pricing

One plan, no surprises

Built for mid-market Shopify stores facing flash sales, restocks, and traffic they can’t predict.
