当前项目数据源较多，目前各个指标均存放在 MySQL 中，后续可能会同步到 Hive、Hudi 以及 ClickHouse 等数据库中。关于 MySQL 数据全量同步到 Hive 使用的是 DataX，但由于其支持的数据源较少，因此需要调研新的数据集成与同步框架。 在初步对比 flink_cdc 和 seatunnel 之后，考虑使用门槛，先调研 flink_cdc～～

fix: #52

when #27 is ready we can add [Catalog](https://github.com/apache/paimon/blob/release-0.8.2/paimon-core/src/main/java/org/apache/paimon/catalog/Catalog.java) API. Maybe we can add struct with definition first, the function and the detail behavior can be implemented for the further PRs.
