Proven ML Data Extraction from Legacy Telecom OSS

🔑 Enhanced Key Takeaways

• •Debezium MySQL connector supports GTID for seamless failover in high-availability clusters and incremental snapshots for efficient initial data capture[2][7].
• •Using Avro serialization with Debezium reduces message size by up to 50% compared to JSON and improves schema evolution tracking via a schema registry[2].
• •Debezium integrates OpenTelemetry for distributed tracing of CDC events, enabling correlation with downstream processing in tools like Jaeger[5].

🛠️ Technical Deep Dive

• •Debezium MySQL connector configuration includes database.include.list to specify databases for CDC, table.include.list or table.whitelist for tables, and Single Message Transforms (SMTs) like ExtractNewRecordState to modify events[1][4].
• •Heartbeat configuration in Debezium ensures offset commits during low-activity periods to prevent consumer lag[5].
• •Security features include SSL/TLS for MySQL connections (modes: disabled, preferred, required, verify_ca, verify_identity), SASL/SCRAM with TLS for Kafka, and mTLS support[5][6].
• •Change events include fields like ts_ms (processing time), database and table identifiers, ddl for schema changes, and operation types (CREATE, ALTER, DROP)[7].
