PeerDB is an open-source data movement and replication platform designed specifically for PostgreSQL databases. It enables real-time Change Data Capture (CDC) and streaming replication between PostgreSQL and various data warehouses like Snowflake, BigQuery, and ClickHouse, making it easier to build data pipelines without complex ETL infrastructure. The platform focuses on providing high-performance, low-latency data synchronization with minimal impact on source databases, offering features like parallel processing, automatic schema evolution, and support for large-scale migrations. PeerDB aims to simplify the traditionally complex process of moving and syncing data across different database systems while maintaining data consistency and reliability.
