Database replication is the lifeline of modern data systems β powering everything from zero-downtime migrations to real-time analytics.
But hereβs the challenge: most tools today β whether legacy like Oracle GoldenGate or modern like Fivetran, Hevo, or complex Kafka+Debezium setups β struggle with heterogeneous databases, schema evolution, and DevOps agility.
Thatβs where Helyx steps in.
π What is Helyx?
Helyx is a CLI-first, Kafka-native replication engine built for real-time, zero-downtime, cross-database replication.
It supports:
Oracle β PostgreSQL / MySQL / MongoDB
PostgreSQL β PostgreSQL
Future support for MySQL β MongoDB and more
Unlike traditional tools, **Helyx **is developer-friendly, schema-aware, and deployable as a single JAR file β no GUI, no vendor lock-in, no black-box pipelines.
βοΈ Helyx Key Features
π Heterogeneous Replication Made Simple
Seamlessly replicate between different database engines β Oracle, PostgreSQL, MySQL, and MongoDB β with minimal config.
π§ Auto Schema Evolution
New column in Oracle? Helyx detects and evolves the schema in Schema Registry and the target DB automatically.
π§° Lightweight & DevOps-Ready
No bulky GUIs. Just a JAR, CLI commands, and config files. Ideal for CI/CD, GitOps, and containerized workflows.
π Real-Time & Event-Driven
Built on Kafka with support for Avro, Schema Registry, and Debezium-style CDC β enabling microservices, data lakes, and lakehouse use cases.
π§© Flexible Deployment
Run on-prem, in the cloud, in air-gapped environments β or all of them. Helyx is environment-agnostic.
π Secure & Observable
Supports fine-grained logging, CLI-based monitoring, and secure Kafka + SSL/TLS configs out of the box.
β
Ideal Use Cases for Helyx
π Oracle to Postgres Cloud Migrations (with zero downtime)
π§ͺ Data synchronization for test/dev environments
π Hybrid or multi-cloud replication
π§© CDC for event-driven microservices
π§ Real-time data lakes/lakehouses ingestion
β¨ Final Thoughts
In an era of real-time analytics, hybrid-cloud architecture, and data-driven applications, replication canβt be an afterthought β and it canβt be a black box.
Helyx is built for:
- Teams that want control without complexity
- DevOps-first environments
- Real-time, heterogeneous, scalable data movement
