[GitHub] [inlong] e-mhui opened a new pull request, #7399: [INLONG-7128][Sort] Upgrade oracle cdc to version 2.3

e-mhui opened a new pull request, #7399:
URL: https://github.com/apache/inlong/pull/7399

   Upgrade oracle cdc to version 2.3
   
   - Fixes #7128 
   
   ### Motivation
   
   Oracle CDC upgrade to 2.3 to improve reading efficiency.
   
   > Incremental snapshot is a new mechanism to read snapshot of a table. Compared to the old snapshot mechanism, the incremental snapshot has many advantages, including: (1) source can be parallel during snapshot reading, (2) source can perform checkpoints in the chunk granularity during snapshot reading, (3) source doesn't need to acquire ROW SHARE MODE lock before snapshot reading.
   
   ### Modifications
   
   1. Upgrade the cdc version.
   2. Fit the metric in the incremental snapshot.
   3. Fix the problem that only one record can be read in the incremental snapshot.
