Overview
PostgreSQL-specific schema discovery and management for CDC replication, handling table structures and column type mappings.
Description
CDC PostgreSQL Schema Management provides patched schema handling for PostgreSQL CDC sources. It extends Debezium's PostgreSQL schema management to support RisingWave-specific requirements such as custom type mappings, schema filtering, and recovery-mode schema reconstruction. The schema manager discovers table structures, maps PostgreSQL column types to RisingWave-compatible types, tracks schema changes during replication, and supports schema recovery during connector restarts. This is essential for maintaining accurate type fidelity between the PostgreSQL source and RisingWave target.
Usage
Apply this principle when working with PostgreSQL CDC schema handling, debugging type mapping issues, or extending schema management for new PostgreSQL types.
