Hi, everyone
We know that there are many data transmission products, like Apache Flume, Apache Sqoop, Alibaba Datax, DTStack flinkx etc, we can see that more and more products support creating data transmission task through SQL configuration. So I wana to raise a topic that let SeaTunnel focus on SQL, we can get a lot of benefits from it, and this will be more in line with the goals of the project `Next-generation high-performance, distributed, massive data integration framework`. The SQL is a language-integrated query that allows the composition of queries from relational operators such as selection, filter, and join in a very intuitive way. We can use catalog management to manage these sqls, and not to maintain the api configuration. So, suggest that we can create a new branch which foucus on SQL like api-draft branch, many features need to develop quickly, like cdc, breakpoint continuation, metrics, catalog management, web ui and etc. The goal of the branch is `Data Transmission based on SQL`. If anyone are interesting, looking forward to your ideas, thanks. Best, Leo65535
