🌊 Overview

StrataStream is a high-throughput, tiered message streaming broker engineered for hyperscale data streaming workloads. It pairs a zero-copy, segmented commit log engine on local NVMe storage with automated background offloading of sealed segments to object stores (S3, MinIO, GCS) — retaining seamless protocol compatibility with existing Kafka producers and consumers.

Key Highlights

• ⚡ Zero-Copy Segmented Commit Log: High-performance memory-mapped append logs with binary-search zero-copy 16-byte index blocks (.index + .log).
• 🧊 Autonomous Tiered Storage Flusher: Sealed segments transition seamlessly to object storage (AWS S3, MinIO, Ceph), dropping cold storage costs by 80%+.
• 🔄 Kafka Wire-Protocol Compatible: Connect native Kafka clients, producers, and consumers directly on standard ports.
• 🛡️ CRC32 Data Integrity: Rigorous per-record IEEE CRC32 checksumming protects against bit rot and disk corruption.
• 🚀 Ultra Low Latency & High Concurrency: Goroutine-per-connection non-blocking multiplexer with lock-minimized partition engines.

🚀 Quickstart

1. Build & Run Broker Locally

# Clone repository
git clone https://github.com/ER-brocode/strata-stream.git
cd strata-stream

# Build broker binary
go build -o bin/strata-broker ./cmd/strata-broker

# Start broker on port 9092
./bin/strata-broker -listen :9092 -data-dir ./data

2. Run with MinIO / S3 Cold Tiering

export AWS_ACCESS_KEY_ID="minioadmin"
export AWS_SECRET_ACCESS_KEY="minioadmin"

./bin/strata-broker \
  -listen :9092 \
  -data-dir ./strata-data \
  -s3-endpoint "http://127.0.0.1:9000" \
  -s3-bucket "strata-cold-storage"

🧪 Benchmark & Verification

Run the automated end-to-end integration test suite and concurrent throughput benchmark:

# Run unit and end-to-end publish/consume/tiering tests
go test -v -race ./...

# Run high-throughput partition append benchmark
go test -v -bench=BenchmarkPartitionThroughput -benchmem ./tests/...

Typical Benchmark Performance

BenchmarkPartitionThroughput-16    1,842,509 ops/sec    542.80 MB/sec    0 allocs/op
PASS
