Fix Flink CDC Oracle Data Latency

To address the issue of data latency in Flink CDC Oracle, several methods can be considered:

1. Adjust CDC settings: Review Flink CDC configuration parameters such as binlog file location, read frequency, data emission frequency, etc., to ensure they are properly configured and optimized.
2. Increase resources: Increase the computing resources of the Flink cluster by adding more TaskManagers or adjusting memory configurations to improve the processing speed of data.
3. Optimize SQL queries: check the performance of SQL queries, ensure optimization of query statements, avoid full table scans, and use appropriate indexes.
4. Check network connection: Make sure the network connection is stable. If slow data transfer is caused by network delays, consider optimizing the network connection or adjusting the data transfer method.
5. Consider using other incremental synchronization tools such as Maxwell or Debezium, which may improve the efficiency and speed of data synchronization.

In conclusion, adjusting configurations, adding resources, optimizing SQL queries, checking network connections, and using incremental synchronization tools can effectively solve the problem of Flink CDC Oracle data delays.
