   Hi @mielientiev, I could understand the problem you are hoping to solve, but 
I don't understand why https://github.com/apache/flink-cdc/pull/2220 not 
addressing this issue, as it said:
   ```
   When MySQL is under a dual-master architecture, GTIDs may have gaps, similar 
to A:1-102, 105-150. 
   Such gaps are temporary but will eventually be consistent. 
   But if the CDC happens to recover from the checkpoint when there are gaps in 
MySQL's GTID, it may access non-existent transactions, leading to recovery 
failure.
   ```
   Is it because the previous analysis was not entirely accurate?
