mysql-cdc全量同步阶段能否按照某字段排序读取

[moonService]

rt,在实时计算的过程中需要数据按照顺序进行计算，flinkcdc似乎不支持，我看MySqlSource中没有类似的配置，或者在使用flinkcdc的基础上有什么其他方案。

A table option is provided in the new version 2.3.0.

public static final ConfigOption<String> SCAN_INCREMENTAL_SNAPSHOT_CHUNK_KEY_COLUMN =
            ConfigOptions.key("scan.incremental.snapshot.chunk.key-column")
                    .stringType()
                    .noDefaultValue()
                    .withDescription(
                            "The chunk key of table snapshot, captured tables are split into multiple chunks by a chunk key when read the snapshot of table."
                                    + "By default, the chunk key is the first column of the primary key."
                                    + "This column must be a column of the primary key.");
