Helyx Real-Time Replication
for Modern, Heterogeneous Databases — Enables One Source to Power Multiple Destinations
Across diverse environments seamlessly.
Seamlessly replicate data across Oracle, PostgreSQL, MySQL, and MongoDB — with zero downtime, auto schema evolution, and DevOps-first simplicity.
Real-Time
Delivers continuous, low-latency change data capture (CDC) from source to target — no batch delays.
Schema-Aware
Automatically adapts to schema changes (DDL) without breaking replication or requiring manual intervention
Cross-Platform
Supports replication across heterogeneous databases like Oracle, PostgreSQL, MySQL, and MongoDB.
Lightweight
Runs as a single JAR — no agents, no bloat. Deploys in minutes on any server or container.
CLI-First
Designed for developers and DevOps teams. No GUI dependency. Full control through terminal.
Self-Restart
Automatically detects and recovers from replication drift, lag, or disconnections — with minimal downtime.
Observable
Built-in monitoring via CLI or dashboard. Track lag, throughput, schema drift, and more in real-time.
Air-Gapped
Deployable in high-security, offline, or government environments without external dependencies.
Solution for
Enterprise Database
Replication
Helyx simplifies the hardest part of replication: schema evolution, data-type mismatches, and reliable delivery. Using proven CDC patterns, robust error handling, and opinionated defaults, Helyx gets you from databases to a synchronized state in minutes, not weeks.
Key features
Everything you need for reliable, enterprise-grade, cross-database replication.
Real-time CDC replication
Continuous, low-latency change data capture using battle-tested pipelines.
Schema evolution automation
Detects column additions/type changes and creates safe destination DDL with preview + rollback.
Heterogeneous mapping
Type mappings & SMTs for Oracle → Postgres conversions (DATE, NUMBER, LOBs).
CLI-first experience
Single-binary JAR or container — automatable, scriptable, and CI/CD-friendly.
Enterprise reliability
Watchdog auto-restart, retry policies, idempotent delivery, and ack-based guarantees.
Observability
Prometheus metrics, structured JSON logs, and optional lightweight topology UI.
Lightweight packaging
RPM/DEB, Docker images, and Helm charts for fast deployability.
Secure by default
Secure defaults, TLS, role-based config, and minimal attack surface.
