CDC inputs connect directly to database transaction logs or change streams, transforming each change into a [message](#message) that downstream applications can process immediately. After reading this page, you will be able to: - Describe how CDC inputs capture database changes in real time - Compare Redpanda Connect CDC with Kafka Connect approaches - Identify which CDC input to use for your database ## [](#common-use-cases)Common use cases CDC enables real-time data integration patterns: - Sync data between databases and data warehouses continuously, eliminating batch ETL delays - Build event-driven microservices that react to data changes within milliseconds - Replicate data across regions automatically for disaster recovery - Feed real-time analytics pipelines from operational databases without impacting performance - Keep search indexes synchronized with primary data stores without polling ## [](#cdc-inputs-in-redpanda-connect)CDC inputs in Redpanda Connect Redpanda Connect CDC inputs use declarative YAML configuration and integrate with [Bloblang transformations](https://docs.redpanda.com/connect/guides/bloblang/about/) for data manipulation. This approach eliminates the need for a separate Kafka Connect cluster, and handles schemas through built-in [schema registry processors](https://docs.redpanda.com/connect/components/processors/schema_registry_encode/). | Feature | Redpanda Connect CDC | Kafka Connect | | --- | --- | --- | | Configuration | Declarative YAML | JSON + REST API | | Transformations | Native Bloblang | SMTs (Single Message Transforms) | | Schema evolution | Built-in Schema Registry support | Requires additional configuration | | Deployment | Single binary, managed in Redpanda Cloud | Separate cluster required | For managed Redpanda Cloud deployments, CDC [pipelines](#pipeline) run as fully managed services. For self-hosted deployments, configure CDC inputs using [Redpanda Connect configuration files](https://docs.redpanda.com/connect/configuration/about/). ## [](#supported-databases)Supported databases Redpanda Connect provides CDC inputs for relational databases, NoSQL databases, and cloud services. ### [](#relational-databases)Relational databases - [PostgreSQL CDC](https://docs.redpanda.com/connect/components/inputs/postgres_cdc/) - Logical replication using replication slots - [MySQL CDC](https://docs.redpanda.com/connect/components/inputs/mysql_cdc/) - Binary log CDC with GTID support - [Oracle CDC](https://docs.redpanda.com/connect/components/inputs/oracledb_cdc/) - LogMiner-based CDC for Oracle databases - [SQL Server CDC](https://docs.redpanda.com/connect/components/inputs/microsoft_sql_server_cdc/) - SQL Server change tracking ### [](#nosql-databases)NoSQL databases - [MongoDB CDC](https://docs.redpanda.com/connect/components/inputs/mongodb_cdc/) - Change streams for replica sets and sharded clusters - [DynamoDB CDC](https://docs.redpanda.com/connect/components/inputs/aws_dynamodb_cdc/) - DynamoDB Streams for real-time table changes ### [](#cloud-services)Cloud services - [Google Cloud Spanner CDC](https://docs.redpanda.com/connect/components/inputs/gcp_spanner_cdc/) - Spanner change streams - [Salesforce CDC](https://docs.redpanda.com/connect/components/inputs/salesforce_cdc/) - Pub/Sub API for Salesforce object changes - [TigerBeetle CDC](https://docs.redpanda.com/connect/components/inputs/tigerbeetle_cdc/) - TigerBeetle accounting database change streams ## [](#example-patterns-and-configurations)Example patterns and configurations The following cookbooks demonstrate real-world CDC patterns with complete pipeline configurations. ### [](#oracle-cdc-pipeline)Oracle CDC pipeline See [Oracle CDC patterns](https://docs.redpanda.com/connect/cookbooks/oracledb_cdc/) for complete examples of filtering, transforming, and routing Oracle database changes. ### [](#dynamodb-cdc-pipeline)DynamoDB CDC pipeline See [DynamoDB CDC patterns](https://docs.redpanda.com/connect/cookbooks/dynamodb_cdc/) for patterns that stream DynamoDB table changes to Redpanda. ## [](#suggested-reading)Suggested reading - [Transform CDC messages with Bloblang](https://docs.redpanda.com/connect/guides/bloblang/about/) - [Configure the Redpanda output](https://docs.redpanda.com/connect/components/outputs/redpanda/) - [Handle CDC pipeline failures](https://docs.redpanda.com/connect/configuration/error_handling/) - [Understand message delivery guarantees](https://docs.redpanda.com/connect/guides/delivery_semantics/)
