Architecture That Makes Sense

Built for the object storage era

The Write Path

1
Durable Write to S3
Every write lands in S3 first for immutable durability and 11 nines guarantee
2
Async Index Update
Regional RocksDB indexes sync asynchronously (typically < 30s)
3
Global Availability
Data propagates to all configured regions automatically

The Read Path

1
Cache-First Lookup
Hot data served from local disk cache at <5ms. You control cache budget to balance cost and performance.
2
S3 Fallback
Cold data fetched directly from S3 when not cached. Typical latency 80-200ms with minimal cost.
3
Intelligent Tiering
System automatically keeps frequently accessed data in cache based on your budget

💡 Consistency Model

BoulderKV favors durability and cost efficiency over immediate read-your-writes consistency. Writes are durable immediately in S3, with eventual consistency to regional indexes (typically < 30s). Perfect for read-heavy workloads where strong consistency isn't required.

Pricing Designed for Predictability

Built on principles that make sense for modern infrastructure

💰

Cost Predictability

No surprise bills from read charges. Storage-based pricing that scales linearly with your data, not your traffic.

  • ✓ Object storage economics
  • ✓ No per-read fees
  • ✓ Transparent cost model
📊

Massive Savings

Up to 90% cost reduction compared to traditional KV stores. Perfect for read-heavy workloads that would break the bank elsewhere.

  • ✓ 90% cheaper than in-memory
  • ✓ No vendor lock-in
  • ✓ Bring your own cloud
🎯

Simple Model

Pay for what you store and what you write. Read billions of records without worrying about usage spikes or throttling.

  • ✓ Storage + write charges
  • ✓ Unlimited reads
  • ✓ No capacity planning
