Oracle databases are crucial for business-critical applications, supporting performance-intensive systems like ERPs and CRMs, and are essential for AI, analytics, and reporting tasks. Fivetran's binary log reader for Oracle facilitates efficient change data capture (CDC) by parsing transaction logs, a method that ensures minimal interference with database operations while automatically replicating changes with low overhead. Unlike Oracle's LogMiner and xStream API, which either lack feature support or incur additional costs, Fivetran's solution offers a streamlined approach by leveraging acquired log parsing capabilities from HVR. Supplemental logging, a necessary component for logical replication, involves logging additional data to enable comprehensive data replication, though it may increase transaction log volume. Fivetran's binary log reader, requiring only minimal supplemental logging, excels in capturing all database changes without impacting source database performance, aligning with Fivetran's mission to simplify and enhance data access and replication.
