Drop-in Redis Replacement
Half the Memory, Same Redis
Engula is a Redis-compatible kernel. No code changes, no toolchain swap, no vendor lock-in.
Verify savings with your real data — roll back anytime.
100% Redis Compatible
Passes the full Redis test suite. Existing SDKs, clients, and ops scripts work unchanged.
~50% Less Memory
Running in production at 100B+ daily requests across fintech, e-commerce, and video.
10× Faster RTO
30-day free trial with shadow mode — quantify memory savings before migration.
Verification Flow
Three Steps, Zero Code Changes
From download to quantified savings in as little as 5 minutes.
01
Download the Trial
Get the binary, start Engula in your test environment, connect with existing clients. Supports CentOS 7+ / Ubuntu 18.04+ / major Linux distributions.
02
Evaluate with Real Data
Import your RDB snapshot using ValueSight. Get an Engula vs Redis per-key memory comparison report in under 5 minutes.
03
Shadow Mode Go-Live
Mirror production traffic to an Engula instance and compare behavioral consistency and memory usage. Switch over when ready — roll back anytime.
Engula is a standalone database kernel, not a proxy or middleware. No extra dependencies, no changes to your existing deployment topology.
Production Results
Quantifiable Production Savings
Memory savings validated in real production deployments across industries. Each case was verified in shadow mode before cutover.
Real-time Fraud Detection
Fintech
74%
Memory Reduction
Billions of keys, average value < 256 bytes, mixed read-write workload. Switched to primary after 2-week shadow mode verification.
Recommendation Engine Cluster
Video & Entertainment
43%
Memory Reduction
Hundreds of instances, primarily Hash and ZSet. The 7.7 TB saved directly translates to deferred capacity purchases.
Message Feed System
E-commerce
67%
Memory Reduction
BGSAVE dropped from 45s to 8s, RDB restore from 90s to 12s. Shorter maintenance windows mean fewer business disruptions.
Benchmarks
Reproducible Benchmarks
Real-world performance numbers, verifiable with the trial.
Multi-core Scaling Performance
Multi-Core Scaling (64B)
Engula scales stronger as CPU cores increase. Redis saturates earlier.
