Benchmark data on a 5-node Raft cluster
(c5.xlarge, us-east-1, multi-AZ 1:1:1 topology, memory hot payload backend).
Client ran on a dedicated c5.xlarge instance in the same region.
S2 numbers are from their published documentation (s2.dev).
WarpStream numbers are from their published benchmark
(6×m6in.4xl, S3 Standard, OpenMessaging Benchmark framework).
Latency
| Metric | Snakream | S2 | WarpStream |
|---|
| E2E p99 (same region) | 23ms | <50ms | ~900ms |
| E2E p50 (same region) | 15ms | — | ~500ms |
| Append p50 | 13ms | — | ~250ms |
| Append p95 | 15ms | — | ~500ms |
Durability
| Aspect | Snakream | S2 | WarpStream |
|---|
| Write-path storage | Quorum EBS + S3 Standard | S3 Express One Zone | S3 Standard |
| ACK semantics | Majority fsync before ACK — no data loss window | S3 Express PUT ACK — durable when S3 confirms | Batch flush to S3 — unflushed records in agent memory lost on crash |
| Replication | 3-node synchronous, majority ACK | Quorum over 3 S3 Express One Zone zonal buckets | — |
| Hot data loss requires | 2+ simultaneous EBS failures across AZs before repair | 2+ S3 Express One Zone zonal bucket failures (per-zone durability SLA unpublished) | Agent crash before batch flush (default 250ms window) |
| Storage maturity | EBS gp3 — well-understood failure modes | S3 Express One Zone — no published durability SLA | S3 Standard — 11 nines, proven |
Cost (us-east-1, as of 2026-03)
Per-tenant scenario: 1K streams, 1M appends/day (500B avg), 100 GB retained, persistent connections.
| Per-tenant cost | Snakream | S2 Express | WarpStream |
|---|
| S3 cold storage (100 GB) | $2.30/mo | — (included) | $2.30/mo |
| Platform / service fee | $1.10/mo | — | ~$3.11/mo (platform + agent compute) |
| Per-use charges (storage + transfer + ops) | — | $96/mo | — |
| Per tenant | $3.40/mo | $96/mo | ~$5.41/mo |
