Frequently asked questions

What is real-time catalog change event emission?

Real-time catalog change event emission is the discipline of detecting any field-level change to any SKU in the operator master record and pushing a machine-readable event into every commerce channel the operator sells through fast enough for the channel to react before stale data accumulates customer-side. The discipline has thirteen components and one cross-cutting requirement. Component 1 is field-level change-data-capture (CDC) against the master record using Debezium, AWS DMS, Striim, Fivetran HVR, Airbyte CDC, or Confluent Kafka Connect — emitting changes against price, inventory, availability, description, image, attribute, variant, compliance flag, and recall flag fields. Component 2 is per-SKU change classification (create + update + delete + undelete + recall + discontinue + restock) with change confidence scoring + source attribution. Component 3 is CloudEvents v1.0 event schema with event-ID (UUID) + event-source URI + event-type + event-subject (SKU) + event-time (RFC 3339) + event-data + severity tier + confidence score, with pre-event-state + post-event-state + delta + source-system + CDC log sequence number, with explicit schema versioning + backwards-compatibility spec. Component 4 is per-channel fanout orchestration through an event broker (Apache Kafka + AWS Kinesis + Azure Event Hubs + Google Pub/Sub + Apache Pulsar + AWS EventBridge + Confluent Cloud + Redpanda) into a 14-channel subscriber set (Google Merchant Center + Amazon Seller Central + Meta Catalog + Walmart Marketplace + eBay + Target Plus + Wayfair + Instacart + DoorDash + Shopify + BigCommerce + Magento + WooCommerce + own-website CMS). Component 5 is per-channel format adaptation (required-field spec + field naming translation + character-limit truncation + image resize and format conversion + attribute mapping). Component 6 is per-channel policy validation against MAP + MSRP + FDA 21 CFR Part 820 UDI + FCC equipment authorization + CPSC + per-marketplace policy (Amazon Brand Registry + Walmart Item Maintenance + eBay Item Specifics + Google Merchant Center Disapproval). Component 7 is recall emergency-bypass workflow against FDA 21 CFR Part 7 + CPSC Form 1 Section 15 + Class I/II/III classification + bypass quiet-hours + bypass throttling + CCO and General Counsel approval + CTIA Best Practices public-safety + stakeholder notification across FDA MedWatch + CPSC SaferProducts.gov + USDA FSIS + CDC MMWR. Component 8 is cross-channel idempotency-key deduplication via Bloom filter + RocksDB state store. Component 9 is per-event-type debounce (price + attribute + image + recall on different windows). Component 10 is event replay from timestamp or CDC LSN offset with schema migration + dry-run. Component 11 is 4-tier event severity (recall + price/availability + attribute/description + image/metadata). Component 12 is per-channel acknowledgment tracking with emitted + delivered + acknowledged + failed + retried + DLQ states. Component 13 is per-channel SLA-violation escalation. The cross-cutting requirement is WORM audit trail with SOC2 Type II + FDA Form 2253 + CPSC Form 1 Section 15 export. The product-feed-management market (Channable + DataFeedWatch + GoDataFeed + Lengow + Productsup + Feedonomics + ChannelAdvisor + Wakeupdata + Sales & Orders + FeedArmy + Adfeedlytics) and the PIM market (Akeneo + Salsify + inriver + Pimcore + Plytix + Bluestone PIM + Contentserv) ship excellent primitives at the feed-management and master-record layers. The operator-side architecture sits above both. Completions operates this as the catalog-change-event-emission skill on the product-catalog-canonicalization agent, sibling to product-feed-management + catalog-conflict-resolution + multi-pim-catalog-ingestion + product-compliance + product-traceability-software + bulk-sku-description-generation skills.

Why does nightly feed re-upload break at multi-channel multi-location catalog scale?

Nightly feed re-upload works at single-channel-1,000-SKU scale where the operator pushes one feed file to one channel each night and the channel re-indexes the file. It breaks at multi-channel multi-location catalog scale on three dimensions. First, latency: a recall flag set at 9:14 AM that ships to Amazon at 2:00 AM the next night means 17 hours of continued ad impressions, organic search ranking, and add-to-cart activity on a product the operator is legally required to stop selling. FDA 21 CFR Part 7 and CPSC Form 1 Section 15 do not accept nightly-feed latency as a defense; nor does the state-AG that follows up after a recall. Second, channel divergence: a single nightly feed file does not encode per-channel format adaptation (Google Merchant required-field spec differs from Amazon Brand Registry which differs from Walmart Item Maintenance which differs from eBay Item Specifics), per-channel policy validation (MAP and MSRP rules differ per marketplace), per-channel character-limit truncation, per-channel image resize and format conversion, or per-channel attribute mapping. The operator pushes the same payload to fourteen channels and absorbs the rejection rate. Third, observability: a single nightly feed has no per-channel acknowledgment tracking, no event-replay from a known offset, no cross-channel idempotency-key deduplication, no per-event-type debounce, and no severity-tiered SLA. When something goes wrong the operator cannot tell which channel acknowledged what, replay only what failed, or escalate the failure. The Channable + DataFeedWatch + GoDataFeed + Lengow + Productsup + Feedonomics + ChannelAdvisor + Wakeupdata + Sales & Orders + FeedArmy + Adfeedlytics vendors do not ship the missing layer — they ship excellent feed-management primitives, but the operator is accountable for whether 1,000-100,000 SKUs × 14+ channels stay synchronized in real time with audit-defensible recall behavior. The fix is a 13-component event-emission architecture above the feed-management primitive.
