Indeed, it had some code refactor. the gain is to use the existing SQL API
code to implement a low-level API for users
eg:
Write:
```
DataStream<Row> input = dataStreamGen();
Map<String, String> confMap = new HashMap<>();
confMap.put("connector" , "hudi");
confMap.put("table.type", "MERGE_ON_READ");
confMap.put("path" , "hdfs://127.0.0.1:9000/hudi/hudi_db/mor_test9");
SinkBuilder.builder()
.input(input)
.options(confMap)
.partitions(Arrays.asList("dt", "hr"))
.schema(CREATE_TABLE_SCHEMA)
.sink();
```
Read
```
Map<String, String> confMap = new HashMap<>();
confMap.put("connector" , "hudi");
confMap.put("table.type", "MERGE_ON_READ");
confMap.put("path" , "hdfs://127.0.0.1:9000/hudi/hudi_db/mor_test9");
confMap.put("read.streaming.enabled" , "true");
confMap.put("read.streaming.check-interval" , "4");
DataStream<Row> rowDataStream = SourceBuilder
.builder()
.env(getEnv())
.schema(CREATE_TABLE_SCHEMA)
.options(confMap)
.partitions(Arrays.asList("dt", "hr"))
.source();
rowDataStream.print();
```
