Oracle CDC

Get Started

Oracle CDC Overview

Oracle database services and products offer customers cost-optimized and high-performance versions of Oracle Database, the world's leading converged, multi-model database management system, as well as in-memory, NoSQL and Oracle databases. Oracle Autonomous Database, available on premises via Oracle Cloud@Customer or in the Oracle Cloud Infrastructure, enables customers to simplify relational database environments and reduce management workloads.

The traditional approach to syncing Oracle with complementary data stores is batch-based, where pipelines extract data from the Oracle database system and send it to downstream data stores. Change data capture (CDC) is a modern alternative to inefficient bulk imports. CDC extracts change events (INSERTs, UPDATEs, and DELETEs) in real-time from data stores, such as Oracle, and provides them to a data pipeline.

Decodable + Oracle CDC

Decodable can take input from an Oracle database as a source using the Oracle CDC (Change Data Capture) connector which converts table changes into a stream of change records. Decodable can be a super convenient means to replicate the contents of a Oracle database into a range of systems including messaging such as Apache Kafka, analytical databases such as Apache Pinot, or machine learning feature stores. Decodable's SQL-on-the-stream transformation process also includes data virtualization on change streams so you're processing against the table, not the change records.
