Welcome to Kasho

Kasho solves the age-old problem of “production-like data” for staging, testing, and development environments. It supports PostgreSQL and MySQL databases, tapping into their native replication capabilities (logical replication for PostgreSQL, binary log for MySQL) and putting a transformer in the middle.

What is Kasho?

Kasho consists of two main components working together:

Change Stream Service - Captures changes from your database (pg-change-stream for PostgreSQL, mysql-change-stream for MySQL)
translicator - Applies changes to target databases with optional transformations

Under the hood, Redis is used for reliable, ordered message buffering.

Key Features

🚀 Live, Hot, Compliant Replicas

Stream database changes with minimal latency using native replication (PostgreSQL logical replication or MySQL binary log), including both DDL and DML operations. Your replicas stay in sync automatically.

🔒 Data Transformation

Transform sensitive data with configurable rules before writing to the replica. Perfect for creating GDPR-compliant development environments from production data.

📦 Simple Deployment

Deploy with Docker using a single image containing all components. Available from Docker Hub at kashoio/kasho. Works with Kubernetes, ECS, or any container orchestration platform.

⚡ Bootstrap Support

Get up and running with existing data and zero downtime using the included bootstrap process. Seamlessly migrate petabytes of data without missing a single change.

Getting Started

Kasho requires PostgreSQL 15+ with logical replication enabled, or MySQL 8.0+ with binary logging enabled
