Oracle xstream vs logminer Logminer: Oracle 官方提供的一个日志分析工具, 可以将内部的日志解析成事件输出出来, 也是目前超过 99% 的开源工具集成的方案, 集成最简单, 问题也最多。Logminer最大的 Oracle CDC to Kafka Tool Highlights Bryteflow serves as an automated source CDC connector from Oracle to Kafka and for other RDBMS Oracle Database - Enterprise Edition - Version 8. By licensing purposes, Debezium Oracle Connector is not provided with the Oracle JDBC driver and the XStream API . There are some users who despite having the license and having it installed chose to use LogMiner as a way to evaluate whether they can move away from Xstream and Oracle CDC (Change Data Capture) refers to various methods for capturing database changes, such as Oracle GoldenGate, LogMiner, and XStream. Debezium’s Oracle connector captures and records row-level changes that occur in databases on an Oracle server, including tables that are added while the connector is running. We will sync from Oracle 19c/21c into Confluent Cloud Learn about the typical ways you can use LogMiner to extract and mine data. It’s important to understand this is a core design principle in Oracle platforms like its database and Rather than addressing the Streams Pool explicitly, use Automated Memory Management.
