Debezium vs Oracle GoldenGate

Debezium captures row-level database changes and delivers them to applications as events, so they can respond to inserts, updates, and deletes. Its connectors use database logs for low-delay capture without requiring changes to the data model, and can take initial or incremental snapshots, filter schemas, tables, and columns, and mask selected values. Listed databases include MongoDB, MariaDB, MySQL, PostgreSQL, SQL Server, Oracle, Db2, and Cassandra. Connectors for Vitess, Spanner, Informix, CockroachDB, YashanDB, Ingres, and Milvus are marked incubating and may change without backward compatibility. A common deployment uses Apache Kafka Connect; Debezium can also run through Debezium Server or as a library in JVM applications. Debezium Server can send serialized events to Amazon Kinesis, Google Cloud Pub/Sub, and Apache Pulsar. Ready-to-use transformations support routing, filtering, and event flattening. Debezium is free under the Apache Software License 2.0. Its quay.io container images are for testing and evaluation, not production.

Oracle GoldenGate is a data replication service supporting change data capture and multi-way movement between databases. It offers hybrid deployment, cross-region replication, and data transformations. Supported systems include Oracle Database, MySQL, PostgreSQL, Microsoft SQL Server, Db2 LUW, Db2 z/OS, Db2 for i, Sybase, Teradata, Yugabyte, TimesTen, MongoDB, and Cassandra. Oracle GoldenGate Free provides a free perpetual license, a recipe-driven interface, and Docker deployment. OCI GoldenGate is listed at $1.34 a month, with each partial OCPU hour billed as a full hour and usage of 1–24 OCPUs. OCI GoldenGate BYOL is a bring-your-own-license route for on-premises users, with pricing not publicly listed on the opened pricing page. The service is available on Linux and the web. Oracle was founded in 1977 and is headquartered in Austin, Texas, USA.
