Debezium connector configuration
CDC pattern selection (log-based, trigger-based, timestamp-based)
Initial snapshot strategy
Schema change handling
Exactly-once delivery configuration
Sink connector setup
Tombstone handling
CDC monitoring setup

Input Schema

{
  "sourceDatabase": {
    "type": "postgres|mysql|oracle|sqlserver",
    "connection": "object"
  },
  "tables": ["string"],
  "targetSystem": "kafka|kinesis|pubsub",
  "requirements": {
    "latencyMs": "number",
    "exactlyOnce": "boolean"
  }
}

Output Schema

{
  "connectorConfig": "object",
  "snapshotStrategy": "object",
  "schemaConfig": "object",
  "monitoringConfig": "object",
  "documentation": "string"
}

Target Processes

ETL/ELT Pipeline
Streaming Pipeline
Data Warehouse Setup

Usage Guidelines

Identify source database and tables for CDC
Define target streaming system
Specify latency and delivery guarantees
Configure appropriate snapshot strategy for initial load

Best Practices

Use log-based CDC when possible for minimal source impact
Plan initial snapshot strategy carefully for large tables
Implement proper error handling and dead letter queues
Monitor replication lag and connector health
Test schema evolution handling before production
