Illustrative deployment scenarios

Every industry has a database
that won’t sit still.

Marketplaces, multiplayer games, fleets of trucks, banks, hospitals, telcos, power grids, etc all depend on changing data. These scenarios show how Remac can fit common deployment patterns.

These are modeled scenarios, not customer deployments, testimonials, or measured customer results.

Scenario 01E-commerceHigh-growth marketplace · 40M SKUs · PostgreSQL → Kafka + Snowflake + Elasticsearch

A 40-million-SKU catalog that's finally consistent everywhere.

One source of truth feeds the warehouse, search index, and event stream without a nightly ETL or 15-minute re-index cycle.

01 · The challenge

A nightly job loaded the warehouse and a cron re-indexed Elasticsearch every 15 minutes. Buyers searched for items that existed but weren't indexed yet, and merch dashboards trailed a day behind.

Search stale up to 15 minutesDashboards a day behindFull re-index hammered the DBInventory drift between services
02 · The approach

One Remac data path reads the catalog's replication slot and fans selected changes out to three sinks: the warehouse, search index, and a Kafka topic for downstream services.

Scenario takeaway
Scenario 02GamingLive multiplayer · 12M DAU · multi-region · PostgreSQL → Redis + regional Postgres & MySQL

Current leaderboards and convergent game state across regions.

CDC sends selected player changes to Redis and replicates game tables to PostgreSQL and MySQL nodes across regions.

01 · The challenge

Leaderboard data lived in Redis with TTL-based expiry. A short TTL caused miss storms on hot keys, while a long TTL served stale standings. Three regions also used a mix of PostgreSQL and MySQL replicas that required separate maintenance.

02 · The approach

Remac sends selected row changes to Redis and replicates selected tables to PostgreSQL and MySQL nodes across regions through one configured path.

Scenario takeaway
Scenario 03Logistics · MobilityFleet & delivery platform · 250k vehicles · physical + logical · PostgreSQL → S3 + Kafka

Fleet telemetry in the lake, and a recovery story that holds up.

One Remac data path supports continuous data-lake ingestion through logical processing and point-in-time recovery through the physical path.

01 · The challenge

Custom scripts and Airflow DAGs landed vehicle telemetry in S3. Nightly backups risked a full day of loss. Services polled each other for the latest vehicle state.

02 · The approach

Remac streams CDC to S3 as JSONL and to Kafka for downstream services. It also captures the required WAL for point-in-time recovery.

Scenario takeaway

More patterns across data-intensive industries.

These patterns fit systems that need selected committed changes moved, retained, replicated, or replayed.

Fintech
Real-time fraud analytics

Stream selected committed transaction changes to the warehouse so fraud systems can work with live data.

→ batch → real-time
Healthcare
WAL-level audit

Capture selected committed changes below the application layer, with available source and transaction context.

→ declared audit record
Ad-tech
Event stream to bidders

Impressions and clicks to Kafka in real time, not hourly batches.

→ batch → streaming
EdTech
Progress sync across services

One source of learner state, fanned out to every service in order.

→ N polls → one pipeline
Telco
Network event capture

High-volume CDR and session events streamed straight to the lake.

→ high-throughput streaming
Energy · Utilities
Sensor & meter data

Deliver selected meter changes continuously without a separate Airflow ingestion path.

→ DAGs decommissioned
Government
Append-oriented record-keeping

Preserve selected committed changes to public records with available operation, position, time, and transaction context.

→ append-only S3 archive
Travel · Hospitality
Inventory & pricing sync

Converge selected room, rate, and availability state across search and sales channels.

→ fresher channel inventory
B2B SaaS
Customer data fan-out

Send one selected change to required services and warehouses under one declared delivery policy.

→ N integrations → 1
Media · Streaming
Recommendation freshness

Feature store updates as soon as a watch or like lands.

→ real-time features
IoT · Manufacturing
Device state sync

Edge and plant-floor changes to the cloud, in order, with retries.

→ ordered, retry-aware
Retail · POS
Omnichannel inventory

Converge selected stock state across stores, the warehouse, and online systems.

→ convergent inventory state

Illustrative patterns only. Actual outcomes depend on the source, workload, sink, configuration, and declared processing policy.

One processor. Six transaction log functions.

Move committed data through one controlled path, with explicit ordering, delivery, and recovery boundaries.
