High-performance materialized views
built on managed event sourcing.
Append events to immutable logs, deploy WebAssembly views to precompute state, and query results with consistent low latency. No infrastructure to manage.
How it works
Three steps to production
Append events
Send events to immutable logs. Events are ordered, never modified, and never deleted.
Deploy views
Upload WebAssembly views that process events into materialized state like totals, aggregates, or projections.
Query instantly
Query view results in milliseconds. Strong consistency ensures you always see the latest state.
Why Primatomic
Built for engineers who ship
Ship faster
No Kafka maintenance, no Kubernetes clusters, no operational complexity. Just append events and query state.
Data you can trust
Immutable logs with full history. Automatic snapshots. S3-backed archives. Node failures don't lose data.
Performance you can design around
Consistent millisecond reads for materialized views, including tail latency you can depend on.
Use cases
Perfect for
E-commerce platforms
Track orders, inventory, and customer history. Rebuild state from events for audit trails and analytics.
Financial applications
Maintain immutable transaction logs. Compute balances and positions through materialized views.
ML feature store
Turn raw user events into materialized features. Views continuously project event streams into up-to-date feature vectors.
SaaS analytics
Capture user events. Materialize usage metrics for billing and product insights.

Primatomic vs. alternatives
| Primatomic | Kafka + custom | Database triggers | |
|---|---|---|---|
| Infrastructure | None | Kafka, Zookeeper, consumers | Your database |
| Snapshots | Automatic | Manual | N/A |
| Compute isolation | WASM sandbox | Shared process | Same as app |
| Pricing | Usage-based | Infra + engineering | DB + complexity |
Reliability
Built for durability
Three layers of persistence ensure your data is always safe
S3 Archives
Every event persists to S3 independently. Replay from any point in history, even after stream retention expires.
Automatic Snapshots
View state checkpoints to S3 at configurable intervals. Fast recovery without replaying entire event history.
Automatic Failover
Cluster coordination ensures exactly-once processing. When a node fails, another picks up seamlessly.
