Flink MySQL CDC initial模式拉取数据全量数据是走的jdbc吗

[wloverine]

如题，从源码的注释上看，earliest模式是全部读binlog，而对initial模式的描述并没有说明snapshot部分是怎么拉取的，是走的jdbc吗

[SML0127]

In initial mode, flink cdc use incremental snapshot.

An incremental snapshot divides the table into chunks, and fetches the data from the table on a chunk-by-chunk.

During this process, a JDBC connection is created.

A JDBC connection is created before fetching a chunk, and the JDBC connection is released when the task of fetching the chunk is finished.

You can see this in MySqlSplitReader.java

Have a nice day😄😄
